i got a PS-50Q96HD samsung set suffers from a green / yellow / red dotted picture ?
orignal fault was: there was no picture when i got set i noticed top left buffer board had blown so i took out top buffer
and also tryed a diffrent bottom buffer board.

( dont have a top buffer avalible yet hence black at top part of picture ) i also tryed another bottom buffer but same problem.

i have tryed a replacment y-sus board & also a diffent control board & also changed the main av board.
i have attached a picture of the fault.



its got my puzzled anyone have any ideas what fault might be with bottom part or picture?.

The chance of having a bad upper and lower drive board is slim to none unless the panel is bad.

hi minnie i have made a video to show you fault better

http://www.youtube.com/watch?v=AKus6DnrorA

theres no colored vertical lines i can see when set comes on so i thought pdp maybe ok?

however what are the symptoms of a faulty pdp?

i have a q97hd & also a c96hd samsung both have these same symptoms ?

as i can only fit 1 buffer as i do not have a top buffer untill i can get hold of one i have noticed the 3 ceramic resistors on the y-sustain are getting red hot?
