2.12. LAMP INNER HOUSING
This unit includes the light source lamp (UHE:200W), the connector for ballast powersupply and fuse board (FUSE board). The lamp fixed on the base of the lower case isuser replaceable item you can purchase it at EPSON service center.The average brightness of the lamp is 550 ml (ANSI), but it reduces corresponding toits running hours. When the lamp is new, its brightness is maximum. After runningabout 2000 hours, the lamp reduces its brightness to almost 50 to 70 percent of a newone.The fuse board (FUSE board) is provided to determine whether the lamp innerhousing is new one or not, and used to control the end of the lamp life (2000 hours).The connector for ballast power supply is applied to receive the DC voltage from thepower supply unit A, so its lead wire is connected to the lamp.
Figure2- 36 Figure2- 37
1. The light source lampThe brightness of the light source lamp reduces in proportion to its running hours asmentioned above. In this device the standard lamp life is 2000 hours. If you notice thelamp brightness reduces, we recommend you to replace the lamp inner housing evenbefore 2000 hours.The total running hour of the light source lamp is written in EEPROM (IC 500) on theMA board. If the lamp is reaching or has reached the end of its life, CPU (IC503)outputs some signals to control the following.
(1) When the total running hour has reached 1900 hours (1900~2000), an orangelamp indicators blink. The CPU (IC 503) on the MA board has counted the totalrunning hours and has written the running data in IC 500(EE-PROM). The lamp willrun only 100 hours after the orange lamp indicators start to blink, so you shouldreplace the lamp as soon as possible. (If the lamp indicators blink from beginning,the lamp life is no more than 100 hours. Therefore the lamp life may be suddenlyterminated.)

2-32 REV.A
(2) When the total running hour exceeds 2000 hours (the lamp is used), the red Lampindicator start to blink and shut down the ballast power then start the cool downsequence. After that the lamp will not run before you replace it with a new lamp innerhousing.(You can’t replace with used lamp inner housing ) Once you start up with anew lamp inner housing, the fuse on the FU board is blown, so it doesn’t recognize asa new one.

2. Fuse boardThe lamp inner housing is installed to distinguish a new one ( placed and haven’t
started up ) from an old one. This is the board with rated 100mA fuse, a new onehas a fuse circuit. The terminal sections placed on the both ends of this board touchthe FC board installed on the bottom of the light guide unit. The cable of the FCboard is connected to the connector CN400 on the DR board 1, so the signal fromFC board is sent to the MA board via the connector CN400 on the DR board 1.When it is new or changed to a new one, “LSTAT” signal from I/O controller on theMA board becomes high. ( +5VA on the DR board1 pulls up “LSTAT” signal linethrough the FC board and the fuse on the FUSE board.) When “LSTAT” shows high,CPU is reset the lamp total hour in EEPROM ( IC500 ) to zero. After word, I/Ocontroller on the MA board output low level, and connects “LSTAT” signal line to theground through a resistance. Consequently, the fuse on the FUSE board is blown,the lamp total hour in “EEPROM” ( IC500 ) will not be reset, the running hour isintegrated every power ON operation.

3.1 DISASSEMBLY AND ASSEMBLY PROCEDURESThis section explains how to disassemble the EMP-5500. The reassembly procedureis the exact reverse of the disassembly procedure.
(1) Preparatory Procedure
1) Remove any ring, wrist watch, cuff buttons, or other metal accessories that arelikely to get in contact with the equipment.
2) Wear gloves.3) Wear a wrist band and ground it. Place a ground mat.4) Turn off the power of EMP5500 and the host computer.5) Unplug the power cord from the main unit and service outlet.6) Disconnect the interface cable from the main unit.7) Clean the air filter, interface and case cover with a vacuum cleaner.

(3) Limitation of disassembly (Optical engine handling)
The disassembly of the mechanical section is detailed in paragraph 3.2. The opticalengine is one replaceable part. When you order the maintenance parts or request ourrepair service, perform works by the units listed in the table on next page. The opticalcomponents listed in the table are required the mechanical alignment or electricalcorrection in the control circuit. (writing the image adjustment data)
Table3- 21 Optical head unit2 Prism unit3 Light guide unit4 Projection lens unit5 Driver board1/2
These units are specified as “Opticalengine”.(Treat as one replaceable part in thefield maintenance.)
* Do not disassemble the Optical engine.* Do not exchange any unit on the optical engine to the others.
3-2 REV.A
Mechanical adjustments for optical engine.
1. Optical Head UnitThe alignment (height/left and right/concurrent) of the polarization plates (includeR/G/B light valves) is applied in the factory. If the alignment is modified, clear colorimage will not be made, because of the color divergence.
Caution: Do not apply any mechanical stress and also not loosen the screws.
2. Prism UnitTo synthesize the light output from each polarization plate (include R/G/B lightvalves), the alignment (concurrent to the polarization plate) of the prism unit isapplied in our factory. If the alignment is modified, clear image will not be made,because of the pixel divergence to R/G/B synthesizing and projection lens unit,being out of focus and color uniformity.
Caution: Do not loosen the prism unit fixing screws.
3. Light guide unitThe alignment of the light guide unit on the optical head unit is applied (gap andconcurrent to the polarization plate) in our factory. If the alignment is modified,clear image will not be made, because of being out of the brightness uniformity onthe display screen (brightness or chroma is not uniform on the screen.)In consideration of the alignment of the lens array and the mirrors, and also theircombinations, the factory setting is applied to the light guide unit to support thebest display performance. (If the alignment is modified or the location is changed,there comes distortion on the display screen, therefore clear image will nit bemade.)
Caution: Do not disassemble the light guide unit. If you remove the upper guidecover from the unit, the alignment of lenses or mirrors may beunintentionally changed and also dust may stick to the unit.Since EMP-5500 requires very precise adjustment, it can not be adjustedin the field.
3-3REV.A
4. Projection lens unitThe alignment of the projection lens unit is applied (position and fixing torque) inour factory. If the alignment is modified, clear image will not be made, because ofthe pixel divergence.
Electrical corrections i DR board j
Some parts in the mechanical section of the optical system require somemechanical adjustments mentioned above. In the control circuit (DR board 1/2),the output driver for the display signal is slightly different from the output driver ofother device (DR board 1/2) in individuality. The mechanical section itself of theoptical system (e.g. light valves) must be electrically corrected. Therefore to obtainthe best image, not only the mechanical adjustment but the electric correction isrequired. For this reason some correction values are written to Flash ROM of thedriver board 1/2 on factory shipping. For matching the optical system and electricalsystem, the electric correction is necessary. Consequently, the driver board andthe optical block (consists of optical head / light guide unit) make one set.
At the factory shipment, following correction data are stored in the Flash ROM onthe DR board 1/2 according to the specified optical engine.
Gamma adjustment dataFlicker adjustment dataGhost contrast adjustment dataSub contrast adjustment data
For the writing correction values, an expensive, special device and also skillfulengineer are necessary, therefore it can not adjust in the field.
Caution for field maintenance
Observe the following procedure, when you repair. Otherwise, display quality isnot guaranteed, and also EPSON repair service is not available.
1). Do not disassemble the block. (Do not loosen any screws.)2). If either the optical block or the DR board 1/2 becomes wrong, replace
them in set. And when you send back them to us for repair, send backthem in set (by optical engine).
3).The optical block and the DR board 1/2 make the optical engine set, sonever change its combination (e.g. use only the driver board1 for the otherrepair parts).
3-4 REV.A
(4) Precautions
Precautions given to the individual assembly and disassembly procedures. Readthem carefully before starting the assembly or disassembly procedure. A set ofgeneral precautions are given below.As you disassemble the main unit, dust that is sticked to the internal fans and air filtersis likely to migrate and contaminate the light valves R, G, and B which are the heart ofthe display mechanism, thus deteriorating the display quality.Accordingly, before reassembling, check the dust inside of the main unit and, ifnecessary, clean them with a vacuum cleaner.The light valves R, G, and B and circuit board assemblies are highly sensitive to staticelectricity. When you remove a optical engine or circuit board ,place it in an antistaticbag immediately.When you perform the assembly or disassembly operations listed below, check thepertinent unit and its surfaces for any dirt before reinstalling them. If the unit is founddirty, clean it.
1). Removing the optical engine.2). Removing the lamp inner housing.3). Removing the air filter frame.
The speaker unit incorporates a permanent magnet. Keep it away fromelectromagnetic media such as floppy disks and magnetic cards.
Handle the optical engine(projection lens and light guide units) with care as they arehighly susceptible to vibration and shock.
Do not try to disassemble any part (e.g., power supply unit) that is not covered in thismanual.
