Polaroid 1913- TDXB, turns on, comes up to Polaroid logo, might even get to channel selected, shows picture and sound, then screen goes black. Turn off, repeat, approximately 5-7 seconds. Is the inverter my problem and is there a known component(s) I should be looking for such as bad caps?

I was having same problem, and think I got lucky and found fix.

Try unplugging the TV and waiting 30 seconds, then plug back in.

You will likely get blue screen with "No Signal".

Go to Menu, then scroll down to "Setup". Select "Factory Reset" then hit "Yes."

This did it for me. Wish you all luck.

what you need to do is call direct tv support they should have a code for you

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!
