I have a Viewsonic VX2235WM-3 with a short somewhere on the circuit board that is attached to the LCD screen. I have isolated the shorted fuse, tried to replace it and it shorts out right away.
I've seen posts that suggest connecting a light bulb in place of the fuse. What type of light bulb? After the bulb is attached, I assume I power up the monitor, but what am I looking for? I'd assume the light bulb will go on, and something on the circuit board will start to overheat. Is this correct?
If I can't power up the unit due to it's layout, is there anyway I can connect a small battery up to the circuit board and start troubleshooting that way?
Really I think what I need is guidance in troubleshooting a short circuit I've attached a couple of pictures. I've searched the forum for postings on shorts, but none of them really address how to troubleshoot it.
Thanks in advance.
