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

Polaroid TDX-02610B, Tv was working fine, turned it off, now when I turn it on it flashes polaroid then goes black.


If it is only the screen going black but the TV remains on and you can hear audio, then there is a problem with the backlight. It could be due to bad capacitors or it could be a faulty inverter. It requires repair by a competent engineer.

Polaroid 4241-TLXB wont stay on


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!

Tv suddenly shuts off then blue screen


Examine the electrolytic capacitors on the power supply circuit board. If they have vented, then replace them with premium quality units such as Panasonic/Matsushita from Digikey. Should restore your power supply immediately and eliminate this problem for many many years. Estimated life 5-10 years. About $10.00 in parts.

Best to replace ALL electrolytics on the power supply to ensure a long life TV.
