I have an Acer x241w, which I purchased a few years ago. Recently it started failing (going black after a second or two) and when I opened the case, I discovered a bunch of bulged capacitors, which I promptly replaced with the good brand ones. The problem was resolved easily, however after one week of faultless service the monitor started to behave rather strange. When it is cold, it starts just fine and keeps going but if it goes to the 'stand by' mode or the power turned off I have to wait until it cools down to get the picture back. If I turn the power back on after a short time while it is still hot the screen goes black again in a few sec. I had to turn off the stand by mode completely and have it running for the whole day to avoid the problem.
Sounds like a capacitor problem, but which one? I replaced all capacitors on the PSU and even the logic board (excluding the biggest one on the PSU board - looked fine) .
Any clues?
