Sanyo Dp46819 - White Screen

[kevinjo]

I know this has been covered in some areas but I wanted to know if it was possible to fix a screen which was white washed? The Tcon is functioning properly as is the main. I am 100% confident it is the screen. The image is there..just too white!!!! Thanks in advance.

I also tested all VG test points and all are incremently higher then the next.

What is the model number of the t con? Does it have that as15 gamma chip on it. It sounds like a gamma issue

Yes. I tested all points on the TCON and they are all incremental. SO the TCON is OK. VGAMA 1 to 20? Started out at avolt then went up to like 14 or 15v. I was wondering if a chip or something can be changed on the Screen driver board?

Have you tested the VG test points?
