My Toshiba Regza 32 inch lcd tv has a serious problem, on occasion the screnn will turn a fuzzy green color and turn itself off, usually a few loud popping noises also occur after it shuts off then the orange indicator light will flash three flashes at a time. I can ususally wait a while and it will turn back on and be fine for a long time sometimes days, weeks, or months even. I don't have the model number handy, but if it matters, it does have the built in DVD player. Any ideas on what the issue may be?

Have you tried resetting the TV's settings to the factory default?
You should be able to do that within the settings menu on the TV.

where can I get a replacment stand for a toshiba W42LT66

Sorry but the model number is not coming up in my list, which is it 32 or 37 in?

Make sure set on air,not cable in menu setting,Get a digital antena or a rooof antena.Hook up u should get the DTV free signal.

THe most likely cause for this problem is bad connection of the cable connecting the main TV board with the LCD controller. It's called LVDS cable and is hard to miss, usually fat round and black, connecting a board from the chasis with a little board in the top center of the LCD assembly.

I'd open the TV and gently try and reattach the cable to see if that yields any results. You can try it a few times, in fact I'd do it while the TV is open and working so I can better see if adjusting it makes a difference.

There's also a chance that the LCD logic itself got burned and misses on one of the colors. But I don't remember ever seeing that.

Buy a flat panel bracket.Use a stud finder and bolt to the wall studs
