<strong>LC</strong>D panels used for this model can not be replaced separately. Do not disassemble the <strong>LC</strong>D Panel/Prism Ass’y.<br />

After replacing <strong>LC</strong>D Panel/Prism ass’y, please check the following points.<br />
- Check that there is no color shading at the top, bottom, left or right of the screen. If there is, try to remove the<br />
shading following to the chapter “Optical Adjustment”.<br />
- Check the white balance. If it needs the adjustment, adjust the white balance following to the “White Balance<br />
Adjustment” , “Gamma Adjustment” and “Common Centre Adjustment” in the chapter “Electrical Adjustment”.<br />
- Check the white uniformity on the screen.<br />
If you find the color shading at the some part of the screen, it needs to take the color shading adjustment. This adjustment<br />
