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.

Re: Problem with View Sonic lcd monitor

Great Thanks!
I'm good with soldering so I will probably change them all but is it expensive or hard to find? Also I think i remember reading something about changing all the caps is risky is that true?

Re: Problem with View Sonic lcd monitor

The model is a View Sonic VX2255WMB. Here are some of the pictures the first one has the capacitor that is bulged and squeaks it is a (105°C 1000uF 10v) . I just added the others just in case I missed something.

I have a really nice View Sonic LCD monitor that doesn't work. when I plug it in the power LED starts blinking, but I'm pretty sure its a capacitor because it is bulged and I can hear it squeaking in sync with the blinking LED, and right as the capacitor stops squeaking the light flashes really bright. It looks like the LED is getting more power than it should and makes it flash wight/orange. If it is the capacitor how hard is it to replace the capacitor? any help would be greatly appreciated!
