SAFETY PRECAUTIONS

GENERAL GUIDELINES 1. It is advised to insert an isolation transformer in the

AC supply before servicing a hot chassis. 2. Always use the manufacturer’s replacement safety

components. The critical safety components marked with on the schematics diagrams should not be by other substitutes. Other substitute may create the electrical shock , fire or other hazards. Take attention to replace the spacers with the originals. Furthermore where a short circuit has occurred , replace those components that indicate evidence of overheating.

3. After servicing , see that all the protective devices such as insulation barriers, insulation papers, shields and isolation R-C combinations are correctly installed.

4. When the receiver is not being used for a long time of period of time , unplug the power cord of the Adaptor from the AC outlet.

Color TFT LCD Module is very sensitive both electrically and physically.Users, therefore, are requested to follow the “Guidance of handling color TFT LCD Module”on the followings.

1 -Be careful not to make scratch on the polarizer.

Surface of polarizer is soft and can be physically damaged easily.Please do not touch, push or rub polarizer surface with materials over HB hardness.

2 - Keep clean the surface. Please wear rubber glove when touch the surface of LCD screen. Please use soft and anti-static material as cleaner.

3 -Keep out of water.Water on/in the LCD may cause electrical short or corrosion. Please wipe out dry or water carefully.

4 -Prevent swift Temperature & Humidity change.Instantaneous temperature and/or humidity change can make dew or ice which cause nonconformance such as malfunction. 5 - High temperature & high humidity reduce the life-time. LCD is not proper to be used at high temperature and high humidity. Please keep specified temperature and humidity condition.

6 - Keep out of Corrosive Gas.Corrosive gas effect the polarizer and the circuit chemically and cause defects accordingly.

7 - Electrostatic discharge can make Damage

There are electro-static sensitive components such as CMOS in LCD Module. Please earth human body when handle the LCD.In addition, please do not touch the interface connector pin with bare.

8 - Do not operate for a long time under the same pattern

Operating LCD for a long time under the same pattern can cause image persistence and can damage it. Please follow following guidance. 1. Turn the power off when do not use. 2. Change the pattern periodically. LEAKAGE CURRENT COLD CHECK 1. Unplug the AC cord and connect a jumper between the two prongs of the plug. 2. Turn the receiver’s power switch. 3. Measure the resistance value with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the receiver. When the exposed metallic part a return path to the chassis the reading should be between 4Mohm and the 20Mohm. When the exposed metal does not have a return path to the chassis, the reading must be infinite. LEAKAGE CURRENT HOT CHECK 1. Plug the AC cord directly in to the AC outlet. Do

not use an isolation transformer for this check. 2. Connect a 2Kohm 10W resistor in series with an

exposed metallic part on the receiver and an earth, such as a water pipe.

3. Use an AC voltmeter with high impedance to measure the potential across the resistor.

4. Check each exposed metallic part and check the voltage at the each point.

5. Reverse the AC plug at the outlet and repeat each of the above measurements.

6. The potential at the any point should not exceed 1.4 Vrms. In case a measurement is outside the limits specified , there is the possibility of a shock hazard , and the receiver should be repaired and rechecked before it is returned to the customer.

BLOCK DIAGRAM

The mainfunctionof the IC is toswitch 8 video inputsources on 6 outputs.

Each output can be switched on only one of eachinput. On each input an alignment of the lowestlevel of the signal is made (bottom of synch. top forCVBS or black level for RGB signals).

Each nominal gain between any input and outputis 6.5dB. For D2MAC or Chroma signal the align-ment is switched off by forcing, with an externalresistor bridge, 5 VDC on the input. Each input canbe used as a normal input or as a MAC or Chroma

input (with external resistor bridge). All the switch-ing possibilities are changed through the BUS.Driving 75Ω load needs an external transistor.It is possible to have the same input connected toseveral outputs.The starting configuration upon power on (powersupply : 0 to 10V) is undetermined.In this case, 6 words of 16 bits are necessary todetermine one configuration. In other case, 1 wordof 16 bits is necessary to determine one configura-tion.

PW181Product Specification

General Description The PW181 ImageProcessor is a highly integrated “system-on-a-chip” that interfaces computer graphics and video inputs in virtually any format to a fixed-frequency flat panel display.

Computer and video images from NTSC/PAL to WUXGA at virtually any refresh rate can be resized to fit on a fixed-frequency target display device with any resolution up to WUXGA. Video data from 4:3 aspect ratio NTSC or PAL and 16:9 aspect ratio HDTV or SDTV is supported. Multi-region, nonlinear scaling allows these inputs to be resized optimally for the native resolution of the display.

Advanced scaling techniques are supported, such as format conversion using multiple programmable regions. Three independent image scalers coupled with frame locking circuitry and dual programmable color lookup tables create sharp images in multiple windows, without user intervention.

Embedded SDRAM frame buffers and memory controllers perform frame rate conversion and enhanced video processing completely on-chip. A separate memory is dedicated to storage of on-screen display images and CPU general purpose use.

Advanced video processing techniques are supported using the internal frame buffer, including motion adaptive, temporal deinterlacing with film mode detection. When used in combination with the new third-generation scaler, this advanced video processing technology delivers the highest quality video for advanced displays.

Both input ports support integrated DVI 1.0 content protection using standard DVI receivers.

A new advanced OSD Generator with more colors and larger sizes supports more demanding OSD applications, such as on-screen programming guides. When coupled with the new, faster, integrated microprocessor, this OSD Generator supports advanced OSD animation techniques.

Programmable features include the user interface, custom start-up screen, all automatic imaging features, and special screen effects.
