Sony VPL-ES7 - VPL-EX7 - VPL-EX70 – How to enter to service mode of sony projector – How to adjust the VCOM – How to adjust the white balance – Projector repair and service


Sony VPL-ES7 - VPL-EX7 - VPL-EX70

How to Enter the Service Mode
1. Power on the projector.
2. Push the switches on the remote controller or controller panel as below.
[Enter] > [Enter] > [LEFT ARROW
] > [Enter] key
3. Service mode menu will appear on the screen
Adjustment of Main Board When it is Replaced
Save the Optical Data and Replacement
1. Try to read the optical data from the faulty unit using the Emie Service tool. If succeeded in reading, replacement of the EEPROM is not necessary but the V COM Adjustment should be performed.
2. If the optical data could not be read from the faulty unit in step 1, remove the IC (EEPROM) from the faulty board and replace the IC (EEPROM) of the new board with the removed one. Reference number: U33, U48(ES7), U20(EX7/EX70)
3. Run the RGB and YUV calibration.
ADC Calibration
RGB Alignment Procedure
1. Power on the projector.
2. Input the following signal from the signal generator to the INPUT A connector.
Timing: VPL-EX7/EX70 : 1024 x 768@60Hz
VPL-ES7 : 800 x 600@60Hz
Pattern: 16 gray pattern
3. Enter the service mode and change to page “ADC Calibration”.
4. Press [RIGHT
] key to run calibration.
5. When calibration is executed, the screen brightness changes for approx. 5 seconds. After that, the screen brightness, the RGB Offset data and the RGB Gain data become stabilized.
YUV Alignment Procedure
1. Power on the projector.
2. Input the following signal from the signal generator to the INPUT A connector.
Timing: 480P
Pattern: SMPTE color bar
3. Enter the service mode and change to page “ADC Calibration”.
4. Press [
à] key to run calibration.
5. When calibration is executed, the screen brightness changes for approx. 5 seconds. After that, the screen brightness, the YUV Offset data and the YUV Gain data become stabilized.
V COM Adjustment
By the Ernie Service tool, the V COM data is not replaced. Therefore, perform the V COM Adjustment when optical data is replaced by the Ernie Service tool.
When the EEPROM is replaced, the V COM data is inherited so that the V COM adjustment is not necessary. If flicker is significant on the screen, perform the V COM adjustment.
Procedure: VPL-ES7
1. Input the 100 % flat-field signal to the INPUT A connector and allow the warm-up of 10 minutes aging at a minimum.
2. Enter the service mode and change to page 4 “Vcom & Misc” page.
3. Input the XGA, R-single color, 30 %, single-line ON/ OFF signal.
4. Move the cursor key until it is positioned at Vcom-R Normal.
5. Adjust the V com-R Normal value until flicker is reduced to minimal by [LEFT
], [RIGHT] key.
6. Change the input signal to the XGA, G-single color, 30 %, single-line ON/OFF signal.
7. Move the cursor key until it is positioned at Vcom-G Normal.
8. Adjust the V com-G Normal value until flicker is reduced to minimal by [LEFT
], [RIGHT] key.
9. Change the input signal to the XGA, B-single color, 30 %, single-line ON/OFF signal.
10. Move the cursor key until it is positioned at Vcom-B Normal.
11. Adjust the V com-B Normal value until flicker is reduced to minimal by 
[LEFT], [RIGHT key.
12. Reverse the “Image Flip” upside-down and right-toleft, and repeat the above adjustment procedure from step 2 to step 11.
Procedure: VPL-EX7/EX70
1. Input the 100 % flat field signal to the INPUT A connector and allow the warm-up of 10 minutes aging at a minimum.
2. Enter the service mode and change to page 4 to select “Vcom & Misc”.
3. Input the XGA, G-single color, 80 %, flat-field signal.
4. Move the cursor key until it is positioned at Vcom-G Normal.
5. Adjust the V com-G Normal value until flicker is reduced to minimal by 
[LEFT], [RIGHT key.
6. Change the input signal to the XGA, R-single color, 80 %, flat-field signal.
7. Move the cursor key until it is positioned at Vcom-R Normal.
8. Adjust the V com-R Normal value until flicker is reduced to minimal by 
[LEFT], [RIGHTkey.
9. Change the input signal to the XGA, B-single color, 80 %, flat-field signal.
10. Move the cursor key until it is positioned at Vcom-B Normal.
11. Adjust the V com-B Normal value until flicker is reduced to minimal by 
[LEFT], [RIGHT key.
12. Reverse the “Image Flip” upside-down and right-toleft, and repeat the above adjustment procedure from step 2 to step 11.
