Question about Toshiba 43H71 43" Rear Projection Television

1 Answer

Tv will not turn on

One day I was watching my tv and it just went off, like I had turned it off, which I did not. When I tried to turn it back on with the remote and manually nothing happened. Now the only thing that is on is a blinking red light above the on button. We have tried unplugging, disconnecting, cleaning, etc. but nothing works. If you unplug it for a while and then plug it in and turn it on, you hear a click but then the red light starts to blink again. We are at a loss of what to do. Any help? Please.

The blinking red light is telling you that the set did not start up due to an overvoltage somewhere in the set. Most likely the main power supply has a fault like a bad regulator IC or a component associated with it, or there is a fault in the sweep power supply somewhere. if you have no electronic repair experience, play it safe and call out a tech to assist you with this repair. Good Luck.

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.

Tv screen has turned blue and I can't watch tv


i think by accident you have changed the input when you went to change the volume. look for a button labeled " input" or "video" select on the remote and scroll through the various choices. you should get your picture back.

TV will turn on, but not respond


Good Day, mistymiles;

Try this before calling a factory authorized service center:

Press " menu 2 > 4 > 7 > 0 > enter", on remote. After settings have been initialized > press the system reset button on the front, once the LED stops blinking > reprogram settings and tuner channels (if not using box). IF NOT fixed call for service (get estimate before repair) and suspect repair of DM PCB (printed circuit board).

Good Luck, big IRISH.

Insignia NS-DXA1 - Digital to Analog converter box


I have had my converter box 5 days now. I hooked it up to the TV and set it up. No Problem. Except there are no instructions on how to set up the VCR/DVD player with it, which we use more than we do watching TV. Everything worked fine until on the second day we had it I read I could program the remote to turn the TV on and off. I followed the instructions and the TV went off. When I turned it back on, my remote went berserk. If I try to change a channel it will quickly flip through all the channels until I turn the converter box off. Same with the volume, it goes up and down, up and down until I shut off the box. The remote does not work unless you are about 1 foot away from the box. And the remote has never turned the TV on or off except that first time I programed it.
