Hello,

I have a Samsung 913N 19" LCD display which is playing up - 3 months after
warranty expired of course !!!

Works OK for a while then loses input signal - screen goes black with error
message in box on screen.

Seems to be heat related , if I turn it off for a few hours and allow it to
cool down it will be OK again - for a while.......then the problem returns

Cant find a schematic on web - can anyone give any suggestions on where to
start looking


Thanks

Andrew
