Feature :
The Ernie Service Tool is the application software for performing the tasks such as SAVE and LOAD of
the 3D GAMMA data on the projector that is connected to a PC via a communication function. The Ernie
Service Tool has the following features.
.It can read 3D gamma data from a set and save it in a file.
.It can write 3D gamma data in a PC into a set.
When the optical unit is replaced, load 3D gamma data recorded on the CD-ROM, which is supplied
together with the optical unit, into a set using the application software.
For details of the Ernie Service Tool, refer to the Technical Memo.
.VPL-ES7 set has not RS-232C terminal, use the QUICK ACCESS Assy.
.Remove the rubber cap on the upper left of the rear side of the unit.

2-2-1. 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. (Refer to
“2-5 V COM Adjustment”.)
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.
2-3. EEPROM Replacement
EEPROM of the main board contains the following
alignment data

the signal shown in Fig. 3.
3. Enter the service mode and change to page “ADC
Calibration”.
4. Press [*] 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.
