Television and Home Theater

I have a Norcent 27inch hi def LCD TV. Model number LT-2722. I have had it a little over a year. A few months ago it started flipping off by itself. But I could always turn it right back on. Recently, it started flipping off by itself and the blue power light would not come back on. So I couldn't turn it back on. It has started staying off for hours, even days, at a time. And sometimes it will stay off for just a few minutes. When the tv is on it works PERFECTLY. Great sound great picture.

Let me start by saying I found this thing sitting next to a dumpster. But it has a 33" screen, and I just couldn't resist picking it up to see why it was there. When I first plugged it in, it worked great. It's got a really good picture, and made for a stunning second T.V. in the bedroom. After using it it for a few days, it began to blink on and off. The screen goes black, while the sound continues. The screen will come back on after a random ( I mean REALLY random, sometimes not at all) amount of time. Sometimes flipping the power on and off will recover the picture.

i am having trouble with my projector i am getting nothing when powered up the two lights light up yellow, (lens cap and bulb ) the power button lights up ren and not green. the top sony display light lights up for one second and the unit clicks and does nothing. there is no light coming from the lens and no fan noise or nothing. please help............ the bulb only has 250 hours on it.
