Hello guys,
I hope there are people here who can explain me what bad or blown electrolytic cap change in the circuit. How its capacity is changed?
Recently I had a problem with my Samsung 940N monitor. When computer is started for the first 1 or 2 minutes the picture is slightly flickering, later is OK.
The problem is solved by replacing three bumped caps 470 uF, 25V on power supply board.
I also found two slightly bumped caps on my motherboard, but the it is working fine, so for now I didn't change them. In this case, there is absolutely no indication that something is wrong or not functioning properly because of bad caps. The caps are 1000 uF, 16V.
So, in two cases I had bumped caps and in one case I had indication something is wrong (startup flicker) in other case everything seems OK.
