Hello guys,

My 46" Samsung does some funny things and its hard to explain, half of the screen jitters and gets pixelated... check out this video:

I opened it up to see if anything was visibly damaged but couldn't find anything wrong, didn't see any burnt or bulged capacitors and everything was super clean.

Any ideas...?

Does it do same when using other INPUTS?

Try removing and cleaning both ends of all FFC's that connect to TCON.

VGA - Tuner - Composite - Component

All FFC's that are socketed, that is. Do NOT separate any that are NOT socketed.

Doesn't seem like it needs to be cleaned. Its like new inside, very clean and shiny, no dust, no nothing. Just tried unplugging both ends of all FCC's and plugged them back in but no luck.

It's FREE. Worth a try.
Going on your presumption that it's the TV that's defective ...

When it's doing it, is the OSD / Menus affected too?
Tcon board would be next cheapest try, otherwise defective Panel.
