I have 2 ViewSonic vx2255wmb-2 LCD displays, both with the same problem. When i power either of them on they turn off after about 10-20 seconds, unless they have been sitting for a few weeks then they last about 5 min.
I have replaced all caps except for the big 150uf 420v, this could be the problem and I'm planning on ordering one but it would be nice to know what is really wrong and fix it without doing things i don't have to. I have a third that I replaced a few bulged caps and it has been working fine for about a year now.
I would be very grateful for help.
