Had a similar issue with an old samsung synchmaster. The capacitors were the problem.

There are a lot of similar 10 year old reports on the net. E.g.: https://www.badcaps.net/forum/showthread.php?t=24494&highlig...

Bad caps was a very common problem in the old days, I remember I replaced the ones on my motherboard at least twice. The classical symptom was that heating the motherboard will allow the PC to start.

Yes,"Capacitor plague" it was called. There's an interesting story about espionage and incomplete stolen formula in the wikipedia article: https://en.m.wikipedia.org/wiki/Capacitor_plague
