Mithibusi projection tv turns off

The tv does not really turn on...just a power on light goes on and a second later shuts off. I happens both manually and with remote. The last time the tv was turned off it was done manually. Could the off on switch be stuck? Could it be a short? Does anyone have a suggestion. I tried blowing electrical connector cleaaner and pushed the on off switch several time but no luck...thanks for your help

You have bad solder joints on the circuit board. Check the horz driver transformer, solder these connections. Resolder the connections on the vertical IC. Resolder the connections in the main power supply.

If the light just goes off then look at the ballast . If the whole set goes off then look at the power supply board.

You likely now have one of two things happening:

1. Green power light constantly blinks and will not stop(should blink for 70 seconds and go out).

2. Green power light comes on and a few seconds later goes off.

Which do you have?

When I power up, 5 seconds later this back projector TV turns itself off

t does sound like a bulb problem, either its over heating and shutting off to protect itself, or its already shot. Give a TV repair shop a call and see if they can give you an approximate price, then decide to ditch or repair it.

TV wont turn on, makes buzzing noise and shuts off

I have two RCA HD52W59 TV's. I have had one for 3 years and one 4 years. The one I have had for 4 years is giving me the problem. Last week the tv turned off while watching it. It wouldnt come right back on. 10 minutes later we tried and it worked fine. the other night the kids were watching and it turned off and smelled like something burning. I tried turning it right back on and got no power at all. I tried to turn it on two days later and it made a buzzing noise and the green light went out. Never did get a picture, no powering up on the screen. Any ideas? Don't want to spend alot of money. Really loved the TV hope it isnt junk now. Better yet I hope the same thing doesnt happen to the other one I have.
