Trying to find issue. I have monitor which had overheating problem, was placed in front of the window and sun lights caused overheating to some components internaly after few months started malfunctioning. As a result it restarts constantly (blinking, screen goes black and shows image again) every 3 to 10 seconds. But after few hours of rest it work well for an hour on average.
I have checked power block it works good, also tried connecting other 19.5 V charger block, still the same problem. So it's definitely not power block issue.
Also tried placing two coolers behind monitor processing unit. After that monitor is realy cold, but still restarts constantly every 3 to 10 seconds. But before it starts reseting it work well at least two hours.
What components can cause the issue. Can it be damaged capacitors (relatively because it works until same point)? From which point I should start investigating the problem?
Ps. can't see any damiged capacitors or other signs of overheating.
