How to fix black screen on Polaroid 32" wall mount tv

I had similar problem with my Polaroid 42 inch. The screen would be fine for 10 minutes or so then go black. I found a work around that solved my problem and maybe you can to. What I did was remove the back panel of the TV. Make sure it is unplugged first. You should be able to see the electical board. Somewhere on the board may be a switch that says "Burn" or something with "Burn" in it. I set the switch to the "Burn" setting and the TV has worked fine ever since. Good Luck.

Ur tv now power on only have picture few mins,than dead,have sound only?Yes,than the 1 or 2 the long board call the LCD inverter boards are dead.The LCD inverter long boards help the LCD screen to have a backlight to produced a picture.Tries websites like Shopjimmy.com,Ebay.com to buy 1 or 2 long LCD inverter boards for the replacement.

If there is still about ? 24. Volts coming from the Power Board when it goes dark, it will be the Inverter board that needs replacing. If not, it is the Power Board that needs replacing. The Voltages should be written next to the sockets & plugs on the Power Board.

Ur tuner board is defective.Replace the tuner board will solved this problems.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish tuner board for the replacement.

I think I may have just solved this issue. Remove the back covers and turn the tv on until it the screen goes black. There will be a little red led that will light up when the screen goes black. right above that light there is 4 little swiches, the bottom one is labled BURN. Switch that one to the opposite direction. I don't know how but mine has been working for a couple days now with no issues. GOOD LUCK!

I had the same problem today with the same symptoms. I tried a power reset, removing the cables, checked all inputs and got the same symptoms.

I found a temporary fix. When I turned the TV on, I immediately press the backlight but on the remote until the bar appears then lower the setting down to 10. This may take a couple of tries of powering the TV off/on. Once I got the setting lowered to 10, the picture stayed on. If you invoke any of the presets it will change this setting. I'm going to call someone and try to get more information on a permanent fix.

I hope this helps, at least I got the picture back.

need new tv

This is a simple and common problem. The solder joints on the vertical output IC have cracked loose. I actually did a housecall on the exact same set with the exact same symptoms this morning! A good tech will resolder the pins of the vertical output IC and all other major solder joints on the main board and the set will play fine.
