Re: Samsung LN46A630 white screen issue

One thing I would add about the readings is that the values were very inconsistent until left on for about 10 minutes ... I'm not sure if that is normal or not?

I'm not certain I removed the thermal pad correctly as I do not see any numbering on the chip. Picture attached. I also included the picture of the screen issue when turned on. The lines only show in my cell phone picture.
Also is there any instruction how to take the Gamma readings on this board?
I searched but didn't find any.
Thanks...

Thanks, here is a picture of the board....

Hi all ... new to this board and hoping for some assistance. I searched other postings but couldn't find the exact match for my issue. My thought was maybe the T-Con LCD board but wasn't sure if I could test to be certain.

When turning on the TV the screen would be all white (not polarized). After maybe an hour leaving the TV on, I could turn off and back on and the picture would be fine. Occasionally it would start white and fade to clear picture. Progressively it would get worse and could be on all day before the picture would come back after turning on and off. Now the screen...
