We have a 42" Polaroid LCD TV that has worked fine for a couple of years. Now all of a sudden the screen will goes black every 10 minutes or so. We still have audio and if I turn the TV off and back on the picture returns for another 10 minutes. Any suggestions?
I first changed the 220uf capacitor with no luck. I flipped the BURN switch to on and the set has been working great for a week now. Daughter left it on for about 20 hours overnight with no problem. Anybody have an idea what those 4 tiny switches are for? I have heard these type of switches called "dip switches". They are tiny white switches in a yellow block on the lower left side of the upper circuit board. The top one was labled 40", the next one down was labled 46", the 3rd one was 4 letters "EW" something I think, and then the bottom one was labled "BURN".
I think I may finally have the answer for the "black screen of death" for the 42" Polaroid LCD televisions. I was having the same issue with the screen going black after a couple minutes of being on. I would shut it down then turn it back on and it would work again for 5-10 minutes. On the "power board" which is the board on top, there is a little red light that turns on when the screen would go black. above that there are 4 little switches, the lower on says BURN. I simply switched that over and the television has been working for 2 days for 8 hours + each day. Hope this help. Let me know
