I have 3 u2311h monitors in an eyefinity setup. For aesthetic purposes, I do not want to replace the faulty one with a newer u2312hm. The problem with the faulty one is as follows:
For the past few weeks, when I turn it on, it flashes the screen (ps3, windows 7, whatever is connected) for a few seconds then turns black. Turning it off and on a few times and if im lucky, it sticks and works properly. Recently however, it never stayed on and always went black. I have read online that its a sign of faulty capacitors.
I have opened the monitor and there are two pcbs. One for the main power connector and one for the vga, dvi, usb etc. I cant for the life of my identify any capacitors that look faulty based on "spot a faulty cap" guides on the internet. None of them look bloated :/
I am fairly proficient with a soldering iron so I am confident I can replace any parts of the board. Am I going along the right tracks here or is this problem nothing to do with the capacitors? Also if it is to do with the caps, which ones do I replace? Ones on the power board, or the other board? or both?
Edit: I have replaced all the small caps but unfortunately the same problem was still there. I didnt replace the massive cap on the board as an oversight. I have just ordered a new replacement powerboard anyway so that should do the trick.
