SOURCE: 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

SOURCE: Screen goes black after couple seconds on my Polaroid 42" LCD
I had a TLX-4240B 42" Polaroid LCD TV and the screen would go black after about 10 minutes. There was still sound. I removed the two covers exposing the circuit boards behind the TV. I powered up the TV and waited for the screen to go black (I was going to start trying to pinpoint where the issue was with my trusting meter) then noticed a red light would come on when the screen would go black. there were 4 mini switches right above the red light. I switched the one that said burn and the TV has been working great since. good luck and let me know!

usually capacitors are the problem on the TDA03211c power supply. 450v (volts) @ 10uf. change both. beside inverter filters.
