I have a Viewsonic vp211b flat panel display that's roughly 10 years old (it's still an awesome monitor.) The power supply is an internal Delta ADP-60BF.
The other day it completely shut off. No picture, no power indicator led. Nada. I had to unplug it, wait 2 minutes or so and then plug it back in for it to work for another 45 minutes or so. At which point I would have to repeat the process.
After getting tired of it, I opened the thing up and took the power supply board out thinking it was a thermal/overheating issue. I noticed one of the 3 capacitors was bulging at the top. I figured this is what was causing this thing to overheat and turn off ever hour or so.
The question is, would a blown capacitor cause this behavior? Nothing else "looks" bad on the PS board.
