First off, I'd like to preface this by saying I can confirm it's not due to my tower, since the issue presents itself regardless of location or if it's plugged into anything at all.
To get to the meat of the issue, I own a Westinghouse, 19 inches (pretty sure) and for the past 5 days it's been doing this odd routine where, upon being turned on, the screen would ripple with white bars descending from the top of the screen as though out of focus, emit a high pitched squeal, then shut off entirely (the light for the monitor would be green though, so it was still technically "on.") This would occassionally be remedied by repeatedly turning the monitor on and off until it "fixed" itself.
Tonight however, I was using the monitor when the entire screen got pretty bright, like I set the brightness up 20-30 clicks higher then normal. I tried fixing this by adjusting brightness until it solved itself; the entire screen went white with black lines here and there, no high pitched noise, and would then turn off. Every subsequent attempt to do the "on and off" trick would be met with the same screen; white that gradually gets even whiter in the span of 2 seconds before the screen turns off in a manner similar to when it was just seemingly out of focus.
Is there any way to fix this? Or has my monitor finally died and is irreparable? To add more information that may help, I haven't adjusted anything on the monitor since I brought it back from college (where I didn't adjust anything either) and this, quite literally, just started to happen one day when booting up the computer.
From listening to other threads in this section, try opening it up (if not under warranty still) and checking for busted capacitors. Usually they're bulged or broken at the top.
Westinghouse is a trash brand. It used to be good back 20+ years ago, but now most of their stuff is cheap re-branded crap from wofat inc.
I'd guess that in your case, both the inverter board and the main video board (for lack of better term) died. If just the inverter board died, you can usually buy replacements for them, but the video boards are usually either much more expensive or not available. In any case, it would be much less of a headache to just buy a new monitor from a reputable brand like Samsung or ASUS.
