Ok, so this is actually my TV, not my monitor. But I figure that since it's LCD, it's similar enough. I'm wondering maybe if it's a capacitor issue?
We got a Sceptre 46" LCD from Costco a couple years ago; it's big and heavy but looks fantastic, and it's been working wonderfully. Until last night.
I went to turn it on, and while its red standby light was on, nothing else happened. Eventually, I tried unplugging it and plugging it back in. The first time, it came on but got stuck on the screen showing which input it was using. The next time, it turned on and worked for a few seconds, then a high pitched beeeeeep came out of the speakers. It was still showing a moving picture but was otherwise frozen. After a couple more instances of unplugging/replugging, it finally powered on and worked fine. Until I tried turning it on today after it was off all night. Went through the same thing again, although this time when it finally turned on it worked fine.
Upshot seems to be that once it's on, it's ok. But completely out of nowhere yesterday it started having these power-on issues. Anyone have any ideas other than capacitor problems? Unfortunately we can't really afford to replace it right now, but if it IS a capacitor, I *might* be able to do something about it...
