Take the back off and look on PCB you should see a couple of 1000 uf caps bulged up and change them out.

My polaroid lcd tv, wont turn on, its 16 months old, any ideas?


Try plugging it into another outlet - one which you are certain is working. If that doesn't work, you might have a bad fuse inside your TV. If that isn't it, the power supply board may have failed.

The infrared receiver light just keeps blinking red and TV won't power on. Tried unplugging for a little while but didn't help.


kindly count the blinking led to diagnose where the fault came from..

also try the initial check....open the back cover and inspect the power supply board for any bulged capacitors inside..

40''polaroid lcd(4011TLXB) has power to it but no pcture or sound? whats difference from power supply board and main control board


Power supply module is to supply voltages to the main control board (the board where the TV cable and video cables are connected to), backlight inverter board. You can buy the whole control box which has both board assembly (power supply and the main control board): http://www.shopjimmy.com/catalogsearch/result/index/?q=Polaroid+4011-TLXB+&limit=25

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!

I Think NO expert can help this problem because it free answer


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
