RH32 allows ABL fluctuations tomanipulate the Trigger Po int of Shut

Down as screen brightness varies. ABLis inverse proportionate to brightness.

This prevents false triggering.

Any fluctuations in High Voltage willalso be reflected by the 50P output P/P.By monitoring the 50P (50 Pulse) risesin High Voltage will be sensed. If HighVoltage climbs too high, DH15 will fire

and trigger a shut down event.

If the Vertical Output IC has a problem,R629 will sense the current rise. The

voltage drop will be reflected at the baseof Q604 turning it on and producing a

Shut Down high.

PAGE 10-01

(01) ATSC Reception problems: Important information to gather when encountering a customer with ATSC reception problems. Please gather all information listed below before calling for Technical Assistance. (See below for contact information). 1. Make sure we are dealing with ATSC reception issues only, please. 2. Model and serial number...By the way, we are placing ALL model and serial

numbers on the front right hand side of the units. 3. Did the customer run auto programming? Please run auto programming again just in case. 4. Signal strength on this channel? Available through customer menu. 5. What kind of antenna are they using? Rabbit Ears? Roof antenna? Are they using antenna rotor? Cable? 6. What is the Software version? This information is available through the Customer’s menu. 7. What channel is having the problem? Digital channels are a main channel and a sub channel, always

displayed as : 25-1 or 25-2 and 25-3, 25-4, etc,. Please ask for all sub channels available, sometimes there are more than one or two.

8. Do they know it's respective channel on analog format (NTSC)? Is the analog channel coming in ok? Just to give you an example: San Diego channel 8 NTSC is equal to channel 25-1 ATSC, when you do auto programming, you will see 8-1 on TV OSD, but you can also enter: 25-1 and you will also get to the same 8-1 digital channel. We all must be very familiar with this fact in order to see if we can select the channel directly, without the need to do auto programming. See www.transmitter.com for state by state listing of analog/digital equivalency table, their location and their power.

9. What is the stream reception format? You will see: 480i, 480p, 720p or 1080i on the upper section of the OSD when receiving.

10. What is the Channel content? Is this ABC, CBS, PBS? And station identification is needed, like WYCN TV Channel 5 or whatever.

11. Try to contacted the Local Station? Explain the problem to the engineer. They may be able to investigate and make some corrections. If you did speak to someone at the station, whom did you talk to? Name and phone number or e-mail address?

12. Local stations are starting to provide a feedback for their customers mostly through a web page....They al-ways want to know if customer are receiving the Digital Channels and are always looking forward to get feedback.

13. Try PIP and make sure the PIP channel is also the same channel as the one they are trying to receive with Ant C.

14. Describe problem and if possible, send a picture/drawing or a video. 15. Is sound OK? 16. Customer name and phone numbers, please. Once this information is gathered, please contact Hitachi Technical support (see below) and provide all information gathered. Phone: 800-393-2369 (Authorized Servicers only) Phone: 619-591-5352 (Non-Authorized Servicers only) FAX: 619-482-8045 or E-MAIL: [email protected] IMPORTANT NOTE: Are you aware that HDTV/SDTV Channels that are shown On Screen may not be the actual channel numbers that you would press on the TV remote control to tune that specific channel? In other words, what you see on the PTV Screen is called VIRTUAL CHANNEL. As and example, to receive (8-1) in San Diego (with out running auto programming in a DTV ) you will actually need to tune to channel 55. Because UHF channel 55 is were they are receiving the Digital Virtual channel 8-1. The Virtual Channel information is embedded within the data re-ceived is the Virtual Channel ID. This was decided because the Customer will know that the HDTV channel they are watch-ing will be a known channel in their area. This will help them to recognize the channel of origin. Below is an excellent web site to visit. This can be a tool that will help you KNOW what the actual channel is when you are going to randomly select them by remote control number keys. You can just select it without a need to run auto programming (on most units ~ with exception of the WXW prior to software upgrade). http://www.transmitter.com DTV Channel Allocation for the whole USA…

(02) Lead Free Solder beginning in 2004. 2004 product will use lead free solder (unleaded) to help preserve the environment. Please read these instructions before attempting any soldering work. Caution: Always wear safety glasses to prevent fumes or molten solder from getting into the eyes. Lead free solder can splatter at high temperatures. Lead free solder indicator: Printed circuit boards using lead free solder are engraved with an "F". Properties of lead free solder: The melting point of lead free solder is 40 ~ 50o F. higher than leaded solder. Servicing solder: Solder with an alloy composition of Sn-3.0Ag-0.5Cu or Sn-0.7Cu is recommended. Although servicing with leaded solder is possible, there are a few precautions that have to be taken. (Not taking these precautions may cause the solder to not harden properly, and lead to consequent malfunctions.) Precautions when using leaded solder: Remove all lead free solder from soldered joints when replacing com-ponents. If leaded solder should be added to existing lead free joints, mix in the leaded solder thoroughly after the lead free solder has been completely melted (do not apply the soldering iron without solder). Servicing soldering iron: A soldering iron with a temperature setting capability (temperature control function) is recommended. The melting point of lead free solder is higher than leaded solder. Use a soldering iron that main-tains a high stable temperature (large heat capacity), and that allows temperature adjustment according to the part being serviced, to avoid poor servicing performance. Recommended soldering iron: Soldering iron with temperature control function (temperature range: 320-450 degrees F . Recommended temperature range per part:

(03) Fan Part # GS00821: In Digital Module • The Fan Runs all the time. This is normal. • All sets with a Digital Module (ATSC Tuner) has a Fan. • A cooling fan is utilized in all Digital Modules (ATSC). It is normal for the customer to hear air

circulating and the fan running if the room is quiet. This can be compared to a computer cooling fan as they are very similar. The customer may not be aware of the fact that his or her projection tele-vision has a cooling fan incorporated. Please educate the customer with this information. Do not assume that just because the customer can hear the fan that there is a problem with the fan. Only if the fan produces a grinding or ticking sound should it be considered to be defective.

• These Fans are running ALL the time. This is NORMAL operation. These applies to ALL Hitachi units with an integrated ATSC tuner.

• This is, is getting to be a very important issue for all our customers. Remember, one huge difference between their previous TV sets and any of these NEW Digital Models is the fact that their previous TVs never had a fan...therefore, there was no fan noise at all!

• Now, once they notice the fan noise, some of them do not like it. First thing they do is: They call for service. Many Technicians MAY NOT be familiar with these units, therefore, they can not tell if the noise is actually normal or too noisy!

• Replacing the fan just to see if the noise goes away or to reduce it is just too much work and it will be for noth-ing....then the Customers will be disappointed to find out the noise is still there (after any of the fans/modules/or even complete TV sets were replaced). But once they hear the explanation related to the REASON why they hear this noise, they always understand.

• New Technology requires the use of faster processors, these processors require the use of cooling fans. Al-though minimal, these fans do make noise when they are running, this is "normal" operation noise.

(04) CRT- I need to Change All Three CRTs, what to do? In a situation where it becomes necessary to replace all three CRTs, it may not be as big a job as first considered. There are many times in which if a couple of First steps are followed, the job may be very easy thanks to Magic Focus. IMPORTANT: You must find the reason for the CRT burn ( if this is the reason for replacing all three CRTs at once), be-fore installing the new CRTs. Look for Deflection collapse caused by poor solder connections on the Yoke Plugs, Conver-gence Yoke Plugs, Vertical Output IC, Drive Transformer and/or Flyback. Make sure the H and V Sweep Loss circuit is func-tioning. Make sure the Yoke plugs are seated properly. Clean all Spark Gaps. Pry off the caps on top of each spark gap and clean the contacts with a thin, fine sand paper. Reinstall the caps. Solder all interconnections between the Signal PWB and the Deflection PWB. THINGS TO REMEMBER: • If at least one of the defectives CRTs is properly set up (in relationship to geometry) then it can be used as a guide for

setting up the new CRTs. This means you have checked that the Center is in dead center and that the lines running left to right and top to bottom are straight and all the grids are linear.

• Magic Focus will be your biggest friend in the process. • If at all possible, do not remove all three defective CRTs at once. Leave the best adjusted CRT in place until the other

two new ones have been installed and aligned. • You most likely will not need an Overlay unless the set is already a mess related to geometry. HERE IS THE PROCESS: • After receiving the new CRTs, first determine which of the defective CRTs is best aligned. (This doesn't matter which

color). For our discussion we will say it's the Red. • Remove the Defective Green CRT. • Install the New Green CRT. • Clear the RAM. (With Power Off, press and hold the Service Only switch. The press the Power Button on the Front

Panel). Set will come on with cleared RAM. No Convergence Correction. • Loosen the Yoke on the New Green CRT and rotate it until it matches the Defective Red Vertically and Horizontally

(TILT) while looking only at the center. Don't worry if the Center isn't aligned with the Red. After adjusting the Tilt, tighten the Yoke.

• Run a string from the top left corner to the bottom right corner. • Run a string from the top right corner to the bottom left corner.

(This will give you a center mark where the strings cross.) • Now, using the centering magnet for Green, adjust Green to the center mark where the two strings cross.

Remember that the RAM has been cleared. In this condition the Red is to the Left of Dead Center and the Blue is to the Right of Dead Center. This is normal.

• Now, Power Off the set. Then turn it back on. This will restore the previous Convergence stored data. If you checked the Red centering before all of this began, (Item 1 under Things To Remember above), then the new Green CRT and defec-tive Red CRT centers should now match.

• Run Magic Focus. This should now return the set to proper Convergence or at least very close where only a minor touch up should be required. You can do this touch up now or wait and do it after all three CRTs has been replaced.

Now, do the same thing with the New Blue CRT starting with step (2) above. REMEMBER: The Blue is offset from dead center to the right. Please make sure to check for the exact measurement because each screen size is different. • Run Magic Focus. This should now return the set to proper Convergence or at least very close where only a minor touch

up should be required. You can do this touch up now or wait and do it after all three CRTs has been replaced. • Now replace the Red CRT. REMEMBER: The Red is offset from dead center to the left. Please make sure to check for the exact measurement because each screen size is different. • Run Magic Focus. This should now return the set to proper Convergence or at least very close where only a minor touch

up should be required. You can do this touch up now. • If there is a need for a minor touch up, remember to do the following; • First: Save the new adjustment DATA. Press the "PiP-MODE" Twice (2 Times). After Save is complete, press the PiP-Mode button one time to return to the Digital Convergence Grid. • Second: Perform the Sensor Initialization: Press the "PiP-MODE" once, then press "SURF". After Sensor Initialization is complete, Press the “PiP-MODE” button one time to return to the Digital Convergence Grid. Power off the set. Job complete.

When selecting some HD Channels, the notice reads as follows: "The HD content protection on your display has been compromised. Please use the Y Pb/Pr Outputs for your HD connection". Or "Monitor Does not support HDCP" or “Lower Resolution” or “Snow”. The warning will show up at power on and will remain there if left alone. EXPLANATION: "This is not a problem with the Projection Television". With the addition of Digital transmission, many avenues of private digital data and usage privileges are being incorporated into the transmission stream. During this age of HD infancy, these codes are being manipulated and can generate this situation. HDCP is the issue here. Please contact your local cable operator for additional information. A temporary work-around is to disconnect and reconnect the HDMI cable between your cable box and TV. Your patience is appreciated until this issue can be resolved by the cable operator. NOTE: Both the TV and the Set Top Box Must Be ON.

(14) HDMI Doesn't Work (Also see Service Bulletins PTV 07-01 about HDMI Improvements) Please clean the HDMI input contacts with Isopropyl Alcohol using a stiff thin brush. • Symptom -Using HDMI connection, black picture with NO SYNC OSD.

Sometimes contaminants can cause poor connections on the DVI and/or HDMI inputs. Cleaning these contacts will eliminate the problem. (15) Using the Cutoff Adjustment to check for a bad CRT.

• Symptoms: Also See Item 10 Cleaning Spark Gaps problems and Item 40 • Color Temperature changes. • Picture Flickers. • Brightness fluctuations.

Did you know that you can check for a defective CRT (internal grid shortage) by looking closely at the single horizontal line while in the Cut-Off adjustment mode?

In this mode, the Vertical is collapsed so the Service Technician can adjust the Cut-Off level of each CRT. (Note: This determines the Life Span of the CRT. If this adjustment is too bright, the Tube Life is shortened).

PROCEDURE:

• Enter the I2C Service Menu and Select the SERVICE adjustment by using the cursor down and then press cursor right. Vertical will collapse.

• While looking at the single colored line, look at any color to see if it's blinking or flickering. If it is, the CRT needs to be replaced. The Room should almost dark to make the line easier to see. You may have to turn the Screens up slightly to see the line more clearly. Remember, the line should be just barely visible.

• If a Color can't be turned completely off, this too indicates a defective CRT and can quickly identify when CRT is bad.

• Replace the defective CRT.

(Note: This isn't related to the Digital Convergence Grid. The Cursor (adjustment point) will blink in this mode and this is normal). (16) POD (Cable Card) Possible Problems or POD Digital Tuner Problems: Make sure Software is current 1: Make sure software is current version: (See the Web Site to confirm current version). 2: If after inserting the Cable Card, the unit IDENTIFIES the Cable Card and goes on to provide a

notice as to how to start Service or it just starts receiving the approved programming. If all this goes on, it is obvious that card and the host (receiver) have established what is commonly known as the "Handshake" and all is Normal. If for any reason, this does not happen, and the "Handshake" does not occur, there still may not be a problem. Try leaving the Card inserted for a longer period of time. If this seems to take too long, insert the card just before retiring for the evening. Leave the Card in-serted over night. Set does not have to be on. There are many reasons that the Card may take an ex-tremely long time to initiate the handshake function. This could be due to traffic, server issues, etc... Please make sure to follow these steps first before considering the Cable Card as being defective.

If after an overnight attempt has failed to initialize the Card, then most likely there is a problem with the Cable Card itself. Please get a different or a new Cable Card to try again. (17) POD (CableCARD) no longer works after Factory Reset or Memory Initialize. • The CableCARD will no longer work after replacing the Digital Module. • The CableCARD will no longer work after replacing the Signal PWB with the Digital Module. When the Customer first receives their Cable Card, they must insert the card and have it authenticated by the Cable company. Then the customer must call the Cable company with the Host ID information. After this, the Cable company then sends out data that provides the Cable card with channel mapping and the allowable channels for this particular customer to view. • If a Factory Reset is preformed, the Cable Card is no longer authenticated and the customer must

repeat the process of re-authentication. • If a Memory Initialization is preformed, the Cable Card is no longer authenticated and the cus-

tomer must repeat the process of re-authentication. • If the Digital Module is replaced, the Cable Card is no longer authenticated and the customer

must repeat the process of re-authentication. • If the Signal PWB with the Digital Module is replaced, the Cable Card is no longer authenticated

and the customer must repeat the process of re-authentication. (18) Lip Sync Issues: This is a news letter written by an engineer at KFMB in San Diego. It explains the cause and things that may help when a problem of "Lip Sync" is encountered. KFMB Digital TV Newsletter Number 19 . January 19, 2003 READ MY LIPS The HDTV forums have been abuzz about poor lip sync on several local HDTV channels. This is potentially a real nightmare for digital broadcasters, and I'll take a little time here to explain why, and what you can do about it. By definition, lip synchronization is another way of saying that the audio portion of a TV program matches in timing the video portion. In the good old days, this simply meant that the lower loop of film on the projector was not of the right size because your projec-tor slipped a few sprockets and you would just reach over and adjust it during the next break. In about 1980, video synchronizers started showing up at TV stations that allowed us to use special effects with sources that were of a completely different timing, like remote news vehicles and networks from outside the station. Without those synchronizers, fading or special effects would just look like a mess on-air. However, they introduced a problem: they delayed video without delaying audio. This wasn't much of a problem for a single frame of delay because few people can detect it. But add a couple of frames for network processing and complex effects, and suddenly you have visible lip sync problems. Audio delay units were introduced, but few stations used them. KFMB used a monaural one until we went stereo in 1990. When the Audio Engineering Society (AES) defined digital audio in the early 1990s, they seemingly forgot to deal with synchronizing audio with video. There are no clues built into the AES audio stream for where a given audio frame is in time with respect to an accompanying video stream. There's no chance of having automatic lip sync. Fast-Forward to 1999, we open a new all-digital master control and disk drive servers to replace tape-delivered programming and commercials. Some sources have ways to adjust audio timing, and some don't. Now we have a digital transmitter and an analog one. When producing the news, we find that the more complex a video effect is, the more video delay we have, with real lip sync issues when carrying the video from several remote sites on the screen at the same time. We build a box that tells our new audio synchronizer/converter to delay a given amount depending on the combination of sources used. The box works well. In 2001, we open a new all-digital production control that fixes the variable delay problem. Life is good, but intermittent problems with lip sync still show up. Software bugs and corrupt data occasionally plague the station's digital encoder. Remote satellite sources still have lip sync issues at their source left for us to solve on the fly. In late 2002, our digital stream is added to the local cable companies. Since there's zero transmission loss, they use our on-air signal for a redistribution medium. However, they have to re-encode the signal in order to get the correct channel information, program guide, and 256-QAM modulation scheme, thereby introducing another potential source of lip sync problems. As digital viewers, you too can introduce your own problems: You are at the mercy of electronics designers as to how much audio or video delay they introduce.

(Continued on page 13)

If you use analog cables to transfer audio between your receiver or set-top box (STB) and your audio amplifier/processor, you have a digital-to-analog converter at the STB and an analog-to-digital converter at the processor/amplifier, each introducing audio delay, whether a little or a lot. If you have acoustic effects chosen on your amplifier, you may introduce more delay. If your receiver/STB gets corrupt data or becomes otherwise confused, it can introduce delay by mistake. What's a Mother to Do? First of all, make sure you have a problem. We evaluate for lip sync watching for speech in which the on-camera person moves his or his lips to annunciate plosive "B" and "P" sounds. Be careful that you're not seeing it on a poorly dubbed single commercial or program. We're going to ask you to be forgiving when there may be a temporary problem with a hastily organized satellite remote news story--bad things happen in the field sometimes. If you encounter disturbing lip sync problems, answer a few questions before you ask for help: Does the problem exist on all over-the-air, cable, and satellite channels? If so, you surely have a local problem. Try resetting your receiver/STB and processor/amp by unplugging for a few seconds and then plugging back in. What is the source? Does the problem exist with all commercials, programs, and live news? Note this to help the person you complain to. When did the problem begin? Have you checked the enthusiast forums to see if others have the same problems? A nice website for San Diegans is http://hdtv.forsandiego.com. Have you reset your receiver and lip sync is still an issue on all channels? You should contact the cable company in order to determine whether the problem is with you, them, or their sources. Does the problem exist on only one channel? Call the provider (cable or DBS) or the source channel. Each will have to analyze the source and determine the source of the problem. At most stations, they have access to view their own sources, line output signal, analog air signal, digital air signal, and Time Warner cable analog and digital signals. We count on Cox Cable to evaluate our signals on their system. (19) Losing Channels on 1/2 of the PinP Window (Analog Half)

• Most often noticed when using a Cable Card. If the Cable service provider decides that they are going to all Digital Channels, then our TVs, will lose ALL or most channels on the Analog Tuner side. The Channels they lose will be the ones that are Digi-tal (QAM). Only the Analog channels will remain, if any. There is nothing wrong with your TV set. Please note that this set is using One Analog and One Digital tuner. Every time we use PinP and the 2nd tuner is selected as the Sub picture, the Sub picture can ONLY BE ANALOG (NTSC). DETAILS: As Cable Companies modernize, they are approaching a Digital solution. This improves picture per-formance even on the lower resolution signals and helps to minimize transmission loses. It also im-proves band performance. These Cable companies provide a "Set Top Box" (Cable Box) to receive and decode these digital broadcast. So as it stands right now, the Cable companies can be broadcast-ing Analog (NTSC), Digital NTSC (QAM) and SD/HD Digital (QAM). Note: QAM (Quadrature Amplitude Modulation). If the Customer is using a Cable Box, then they do not notice a problem, since the Cable Box only outputs one channel at a time.. If the Customer decides to hook the Cable directly into the set and bypass using a Cable Box, then is-sues arise that may appear to be a problem. Sets which include an HD Tuner will receive ATSC (over the air SD/HD digital broadcast) and QAM (Cable digital broadcast). The Analog (NTSC) tuner will only receive NTSC analog broadcast signals. Most Customer's who decide to hook Cable directly into the set, will in turn most often decide on using a CableCard application. This will allow the set to receive the Channel Mapping (what channels are broadcast on what frequencies) from the Cable company so their channel selection will match the Channel listings provided by the Cable company. So when they now try to activate PinP and have the Sub picture selected on the Analog tuner, there will be only a few channels available, if any. These will be the NTSC channels only. Many Servicers are trying to "fix" these problems....After replacing many parts, they end up exactly at the same place. PIP with CableCARD will not be getting most channels on the one side using the Ana-log Tuner. There is nothing wrong with your TV set.

(20) The new Remotes MUST be placed in Digital Convergence Adjustment Mode (DCAM) to adjust convergence. ENTERING THE REMOTE CONTROL INTO THE DIGITAL CONVERGENCE MODE (DCAM). To enter the Remote Control into DCAM do the following;

Remote must be in the TV mode. Press the TV key on top right to place in TV mode. • Press and hold down the TV Key • Press the MENU and then INFO key, release the TV key.

RETURNING THE REMOTE CONTROL TO THE TV MODE FOR THE CLU-3842WL Remote will already be in DCAM mode.

• Press and hold down the TV key Press the 0 key then the 1 key to return to TV mode. (21) E947 and E943 are open. IK01, IK02 are found to be the cause problem. Also please Check: CK17, CK18, CK19, CK20 as they may be shorted. (Note: Please use generic capacitors for replacement parts: All Caps are 0.1uF / 50V) Do not order from parts. Obtain this caps. locally… (22) Be Careful Changing Deflection or Signal PWB,

Damage to the interconnect pins can cause problems. Such as "Convergence has problems". (23) After Changing Signal PWB, the Digital Convergence has problems When the Signal PWB is changed, there are some adjustments lost that affect Digital Convergence. These adjustments MUST BE corrected in order for Convergence to function normally. The loss of these adjustments can cause;

• The Deflection Vertical and Horizontal Size to be altered because H POS and V POS have changed. • Magic Focus won't run because Magic Focus has an Overflow Error

To correct this issue: Re-adjust (thorough I2C) H SIZE, V-SIZE, H-POSI and V-POSI (24) White Balance Won’t Adjust

• This can be cause because "Color Temperature" wasn't set to "HIGH" before making these adjustments. • All Color Temperature settings are dependent upon the High Setting.

The Following Adjustments are related to this information: Also, the Initial Values states are a Good Average setting in case the original values were not written down before replacing the Signal PWB.

I2C data for High light white balance • Green : G DRIVE (HIGH) 3F (initial data) (Adjustable) • Red : R DRIVE (HIGH) 3F (initial data) (Adjustable)

I2C data for Low light white balance • Green : G CUT OFF (HIGH) 7F (initial) (Fixed data) • Red : R CUT OFF (HIGH) 7F (initial) (Adj. data) • Blue : B CUT OFF (HIGH) 7F (initial) (Adj. data)

Note: Also it is important to set the Customer's Controls to their appropriate conditions before making these adjustments. VIDEO Control : Contrast is MAXIMUM, Others are center.

(25) After Replacing the Signal PWB, the picture is too small. This is because the Horizontal and Vertical Size pots are at one end.

• Center both pots. • Then adjust Horizontal and Vertical Size

(26) How to Enter the I2C Service Mode. To enter the I2C Service Mode: (With the TV On, Press and hold the MENU key on the control panel, then press Menu ~ 8 ~ Select on the Remote. The Service Menu is displayed.) To Exit press EXIT on the remote or INPUT on the control panel. (27) Factory Reset seems to Lock Up the Set.

After Factory Reset is performed, the set will go all Green and no functions will work. The set must be unplugged, wait 10 seconds, then reapply AC. This is the normal process.

(28) Volume Level doesn't return to last volume level from power off to power on. Turn on “Quick Start” in the Customer’s Menu. (29) Cabinet makes “Popping” sounds.

• This is normal due to heat expansion.

(30) CRT internal grid “Snaps” or may be described as “Pops”. This is normal due during the curing process. This should be rare and eventually go completely away over time. If this continues after the first 90 days or is happening frequently, then it should be considered a problem. (31) CRT Spot prevention. See Service Bulletin PTV 06-01B is the Service Bulletin Section (32) Clock loses time. The Photo Coupler that provides the AC signal to the Microprocessor is located on the Deflection PWB, I-903. (33) Magic Focus Doesn’t Run. (Note related to a Circuit Failure). Make sure the Customer hasn’t set the Convergence in the Customer’s Menu to Manual. (34) Q777 Failure (Shorted) E947 Open. See Service Bulletins PTV 07-02A. Requires installing a Kit X480315. (35) Vertical Distortion (only at the bottom of the picture). See Service Bulletins PTV 07-02A. Requires installing a Kit X480315. (36) Horizontal Line noise at the top corners in bright scenes. See Service Bulletins PTV 06-02. Requires installing a Kit X480315. (37) Dark Picture. See Deflection Section of the Training Package and see Q806 CRT Biasing Circuit for voltages. (38) Contrast will reduce automatically when viewing Photos if left on the screen for 3 minutes. This is normal operation
