Waited a minute, turned it back on, resumed movie. Stood back up, and the same thing happened. Tightened the VGA connector on the laptop (it was screwed into the TV but not the laptop). Then when I stood up, the colors shifted a bit, but the TV did not turn off.
Saturday: Was watching a cartoon (SD over HDMI) and some parts of the set started turning reddish, sort of flickering. Turned TV off and on. It was fine a bit, then came back. Started getting really worried.
Sunday: Started seeing problems where the TV did the "red" business, and would shut itself off as on Friday. Except I'd have to wait a few minutes before it would let me turn it on--not at all its typical power cycle behavior. The flashing red lights on the power button are probably an indicator here. At this point, I thought maybe my TV, maybe my receiver. Preferably the TV actually, as the receiver may be out of warranty. Turned off my receiver, though, and the reddish flickering could be seen in the "Weak or no signal" message. And was present on Component as well as HDMI. Definitely the TV. Got a little paranoid, wondering, "I first saw this with the VGA cable--is it possible the VGA cable has a bad connection or bad wiring or something that is hosing the TV? " So, unplugged the VGA from the TV (boy that's a pain since it was screwed in!) Problem seemed to go away.
Monday: Noticed it again in the evening. And the power cycling problem where it wouldn't come on. Okay, VGA is out of the picture, unless it did permanent damage. Then thought--is it possible my cables are loose? Re-plugged HDMI but it was already tight, as was component. Checked the power cable--now here's the biggie. The power cable had come just a tiny bit loose. I would hardly even call it loose, as it wasn't wobbly or anything, but when I pushed it into the TV it went in another 1-2 mm.
Wednesday (today): So far, haven't noticed any problems again. Wondering if the VGA cable rubbed against the power cable and made it loose or something now.
Does this sound plausible? Anyone else seen it? I'm hoping my little problem is gone for good but I thought I'd throw the observations out just in case anyone else has seen it, or in case it helps somebody else with a similar problem.
