5-8 Lens and Mirror Cleaning

1. Mix the alcohol and ethyl in appropriate proportions.

2. Use a clean cotton cloth or a cleaning paper.

3. Clean the top of the lens by turning it as shown. The pattern starts at thecenter and proceeds outward, as shown below:

4. Use minimal pressure when rubbing the mirror. Otherwise, the surfacewill be damaged.

5-9 Focus Adjustment for projection Lens

1. Input the Cross hatch pattern or lion head patternfrom the pattern generator.

2. Lift up the Focus Cover in the Optical Engine.(Fig. 1)

3. Move the focus adjustment dial to the colckwiseor counter clockwise until the picture is clearly displayed. (Fig. 2)

4. Reposition the Focus Cover in the Optical Engine.(Fig. 3)

5. Check the focus adjustment.

6. Repeat adjustment 1~5, If nessary.



Lamp replacement

1) Failure type : The screen is dark due to low brightness. The lamp does not operate.2) Reference drawings: Refer to Service Manual.

Lamp replacement

0. Place the set on a flat, wide space. (If the set is placed on an uneven space, the lamp may not be well fitted during replacement.)1. Remove one screw on the right side of the back.2. Remove the lamp door.3. Loosen the two screws which hold the lamp in place. (The screws can be loosened but cannot be removed.)4. Hold the knob of the lamp and pull it out.5. Re-assemble with a new lamp in the reverse order.

Method

5-10 Engine Service Method

5-10-1 Lamp replacement Method



5-10-2 BALLAST replacement Method

< Failure type : The lamp does not operate.

1. Loosen the two screws which hold the lamp in place, and then remove the lamp.2. Loosen the screw which holds the connector in place.3. Loosen the four screws on the ballast board.4. Replace it with a new board and re-assemble it in the reverse order.



5-10-3 Color Wheel : When wheel noise occurs.

Loosen the two screws and remove the lamp.

1. Remove the three screws.

2. Remove the dust- preventing tape.

3. Lift up the C/W cover.



Remove the five screws.Lift up the bracket and the light tunnel. ❈ Be careful not to dirty the light tunnel with foreign materials.

Remove the screw at the side of the

light tunnel.

Remove the three screws and replace the

color wheel ASSY.* Caution: Never touch the color wheel. Touch only the instruments.



5-10-4 Screen Tilt : When the screen tilts, or the image position deviates.

Remove the bottom cover.

Remove the cover of the signal terminal.

Fix the safety switch on the right with tape so that the set can be turned on after removing the bottom cover.



Remove the four screws on the upper and lower part of the digital board bracket, and remove the whole assembly without removing the cable.



Place the digital board and the bracket on the back, and keep the cables connected.

Fix the safety switch on the right with tape so that the set can be turned on after removing the bottom cover.

Remove the two screws on the left and the one screw on the bottom right, without removing the engine.

❈ Even when those screws are removed, the board does not separate, it can be moved within the adjustable range because there is a spring screw at the center that holds it.



Turn on the TV to send signals. Then, adjust the screen position, by holding both of the upper corners of the DMD board.

❈ When adjusting the screen, it is better for two people to work together. On person should direct the picture position while the other person looks at the screen.❈ The movement direction of the board and the picture are opposite. - When the board is lifted upward, the screen descends down. - When it is tilted to the left, the screen tilts to the right.

❈ When the picture adjustment is completed: First, tighten the two screws on the left of the DMD board and then slowly tighten the one screw on the bottom right. Be careful not to touch the board while screwing. (When using an electric-powered screwdriver, be careful that the torque is not too high.)



5-10-5 Failure that occurs when the vertical line or the raster is skipped: Always, make sure to replace the DMD board.

White or BlackVERTICAL LINE

HORIZONTAL Black Bar



Remove the two screws on the left and the one screw on the bottom right, without removing the engine.❈ When those screws are removed, the board will not separate. It can be moved within the adjustable range because there are spring screws in the center area which hold it.

Remove the three spring screws at the center area completely.

❈ After replacing it with a new DMD board, tighten screw spring #3 using weak power (below 8kgf). Then, lightly tighten screws #1 and #2 without tightening them completely.

< Service Method >



After assembling the engine into the set, connect the cables and then perform the same procedures for screen tilt adjustment.

❈ When the adjustment is completed, assemble it by half, as shown in the figure, and re-check the picture position. If there is no problem, assemble the bottom cover and tighten the screws.



5-10-6 Foreign Material Failure: Foreign material appears on the screen like a rainbow with pinkand pale green streaks.



< Service Method >

Loosen the two screws and remove the lamp.

2. Remove the dust- preventing tape.

3. Lift up the C/W cover.

1. Remove the three screws.



Remove the five screws.Lift up the bracket and the light tunnel.

Remove the screw at the side of the light tunnel.

Light Tunnel

Fine dusts stick to the light in the out direction.

❈ Blow out the dust with strong bursts of air, and then re-assemble in reverse order. Make sure to work in a clean room to avoid dust getting in again.

❈ Since the existing dust might not be completely cleared, change the direction of the light tunnel after cleaning with bursts of air. - Switch the light input part to the output part, and the light output part to the input part, on a 180 degreeangle. - This failure can occur only when there is dust on the output part. Any dust on the input parts are extinguished by heat

❈ Re-assemble the ASSY in reverse order.

POWER Board, BALLAST or LAMP is defective

Check IC106,IC111 Power on/off, Check VCC, R369(3.3V,300Hz), R166(3.3V,300Hz) ,R175(5V,300Hz)

Troubleshooting


6-2-3 Check the images on the screen

∗ When the

Check if the waveform of RA104,RA106,RA102and RA101 indicate 26V, 7.5V and 126V.

Replace the DMD Panels and sockets if there is nothing wrong with the waveform.

The PCB is defective if the error continuesto occur even after replacing the panels.

One-sixteenth horizontal stripes:

Troubleshooting


∗ When the screen trembles or flickers:

Check R300,R297 74.25MHz

Check IC103 1Pin, R387 150Hz

Check R329(45KHz), R327(60Hz),R319(45KHz), R311(66MHz)

If any abnormality is found, then the IC117 or the PCB is defective.

If any abnormality is found, then the IC114 is defective.

If any abnormality is found, then the IC113 is defective.

Check the voltage and GND of IC115.If the problem continues,replace IC115.

Check the VCC and GND of IC114.Check if R279 and R267 are at 400MHz(by using 1GHz Probe).

Check IC113 VCC, GND.Check IC102 2,4Pin is 1.8V.Check R282 1.5VCheck X102 3Pin and R290 100MHz

Check R294(2.5V), R293(0V), R291(0V)R295(25MHz), R296(25MHz), R292(50MHz),R258(3.3V)

Check the VCC and GND of IC117.

Troubleshooting


∗ When the screen does not apear:

Check the Color Wheel.

Check if the lamp is on.

Check CN107 3Pin, R201,R231 0V

Check IC103 1Pin, R387 150MHz

Check R358 0V

Check the VCC,GND of IC108R242(0V),R243(3.3),R238(3.3V),R244(3.3V),R244(2.27MHz),R150(900Hz),R149(900Hz),R148(150Hz),R147(150Hz),R211(3.3V),R121(0V),BD5(12V),R111(26V),R118(-26V),R1837.5V),R240(3.3V)

If there is something wrong with waveform of C103 or C102, then the IC108 is defective.

If any abnormality is found, then the PCB is defective.

Check the VCC and GND of IC111.If the problem continues, replace IC111.

Check if the waveform of RA104,RA106,RA102,RA101 are 26V, 7.5V, -26V.

Troubleshooting


Check the connector of the IR PCB.Check the Harness connectedto the Digital B'd.

Check the R910 signals of IC337 (MICOM) ->5V, It's okay if a certain pattern of waveformis generated upon pressing the Remocon key.

6-3-1 IR(Remocon) Signal Check

6-3-2 LED Signal Check

Check the signals of the Digital B'd connector(CN303). -> LED is on : 3~5V LED is off : 0V

Check the connector of the LED PCB.Check the Harness connected to the Digital B'd.


6-3-3 KEYPAD Signal Check

Check the signals of the Digital B'd connector(CN307). -> Key is pressed : 0V Key is not pressed : 5v

Check the connector of the KEYPADCheck the Harness connected to the Digital B'd.

6-3-4 FAN_INT Signal Check

Check the FAN. Check the Harnessconnected to the Digital B'd.

Check the signals of the Digital B'd connector(CN315,317 and 320). -> Pin 1 : 0V Pin 2 : 0V Pin 3 : 7v

If there is a defect, the voltage of Pin1will be 5V.

Troubleshooting


6-3-5 Cover_INT Signal Check

Check the signals of the Digital B'd connector(CN310) -> If there is a defect, the voltageof Pin2 will be 5V.
