Bad part(s) on one (or more) of the boards?Wink

IF/when YOU can tell a normal looking part IS bad just by sight (or as you state "sign of anything wrong," apply for a patent quick.
Not all failures will blow a fuse or send up smoke.

I would look towards the y-sus and the x-sus boards. It could also be the digital control board. All of these boards are just unscrew and unplug.

thank you for helpful post,I were thinking the same thing from what I have seen with plasma sets,I have been learning how to fix tv's for about a year,but it is mostly on the old analog sets,the plasma and lcd's are much different I have been looking for some good books on plasma and lcd repair.
I guess I should be looking into the new ledhdtv's that is where things are going now.
