Feature:
The Ernie Service Tool is the application software for performing the tasks such as reading out and writing 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, write 3D GAMMA data recorded on the CD-ROM, which is supplied together with the optical unit, into a set using the application software.
.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.

1-6. Circuit Description
Main Board:
Video input block*1
The video input has two channels: Composite video and S-Video. The 2-channel inputs are sent directly to the video processor, and converted to the digital data by the built-in AD converter of the video processor.
PC input block
There are two channels: Input A and Input B, one of which is selected with the toggle switch. The selected output is input to the video processor and the video buffer. At the video processor, the signal is converted to the digital data by the built-in AD converter. The signal input to the video buffer is output as a monitor out.
To Input A, PC signals, component signals, and video GBR signals can be input. To Input B, only PC signals can be input. (VPL-EX7IN can input only PC signals.)
Audio input block*1
Stereo mini jack input. The L/R input is synthesized internally into a monaural signal. The signal is synthesized by a resistance, so the output level varies between the case where only one channel is input and the case where both channels are input. The standard is prescribed under the condition where only one channel is input.
Monitor output block (PC)
The signals input to Input A and Input B are output. The signal of the channel that is selected with the input toggle switch is output. No output is made if Video or S-Video is selected.
Monitor output block (Audio)*1
The signal input to the audio input is output. This output is variable with the volume control. If a cable is connected to this connector, the output from the built-in speaker stops.
Video processor & System control block
PW-190 made by Pixelworks Inc. is used. This IC performs pixel number conversion, aspect conversion, and OSD addition to the input signals. This IC also controls brightness, sharpness, chroma, and hue.
In addition, the built-in CPU controls the system.
Control target: Control panel, OSD display, lamp cover switch, filter door switch, LED control, serial control
LCD timing generator (DSD) block
The IC for LCD panel made by Sony is used. This IC generates the timing for driving the LCD panel. This uses the method that inverts the driving direction for each frame. In addition to timing generation, this IC performs white balance adjustment, gamma adjustment, and color shading adjustment.
LCD driver block
The drive IC for LCD panel made by Sony is used. This drives the LCD panel in a 12-phase drive method at the timing generated by the timing generator IC. The GBR and the circuit for three channels are equipped.
*1: Not valid for VPL-EX7IN.
