Samsung LNS4695DX bad main board

[budm]

This one is pretty beat up from the out side, the setup menu looks OK, but the video is full of noise. This seems to be common problem when this TV came out, the fix was to replace the main board. So far it is no affected by hot or cold. I will be doing more checking.

This is a very common issue with Samsung DLPs, and I believe the main board is the same or very similar for these LCD TVs. One of those Samsung RAM chips has failed. You can remove and replace them.

The symptoms do mimic that of bad solder connections on VRAM, Same happens to graphics cards for computers.

VRAM on Graphics Cards is BGA, Not sure about in TV's

My symptoms are pretty much just as pictured above.
one notable thing is ant menu driven on screen stuff looks fine.
it just goes wacky with hdmi input, all 4the same. and off air reception is same regardless of resolution it pics up.

This one uses a mix of standard SDRAM and BGA type DDR(1/2).

Re: Samsung LNS4695DX bad main board

I used the spare parts to fix other TVs, I have way many TVs to fix up, when parts of one TV can be used to fix other 3 or 4 then it makes no sense to fix one. Did you try the new chips?

No not sure where that chip is on the board lol. Was hoping I could find a cheaper board but they still want 200 for one
