Problems: The picture will black out at random, but when working the picture is good. TV powers up and works fine for several minutes to over an hour at times. When it goes black, I can sometimes turn it off and back on to get it to work, other times I have to let it rest, no patterns here. When the picture is black, the sound can be heard but it is reduce by about 50%. If left on long enough in the blacked out state, the picture did return once, I found this out by accident when I failed to shut it off.
Also, the Auto Channel Programming feature fails to recognize which channels are strong enough for viewing, thus sets all channels on. As it auto cycles through the channels, it has a blue screen, but the left and right side is blacked out, maybe about 2 inches on each side, looks like a inverted wide screen. :-) I don't think it had the black edges before. Also, I can not manual add/delete channels.
The Rest Of The Story: The TV worked fine until I moved it from one cabinet to another, and left it unplugged for days. After I plugged in back in, the programmed channels were lost. I then found out the Auto Channel Programming Feature failed, so I change the remote batteries, and it still didn't work. The manual channel set fails to recognize the delete command. So I have to manually enter the channel number or step through non-viewable channels to change the station. After using the TV this way for maybe a day or two, the picture started to black out.
I have the back off now. It's been unplugged for a couple of months. Nothing smells burnt, nothing looks fried. I am assuming I can still get shocked, so I am not touching anything.
After the visually inspection, I turn the set on and very carefully adjusted the Screen and Focus controls, both work.
How long does it take this set to discharge?
Should I trash this? Did I maybe break a solder joint moving it? What do you recommend?
Thanks for your time.
