Question about Polaroid Televison & Video
If it powers up to the initial display then the power board is likely good. Maybe the tuner...? there are a couple of Polaroid vids, if this one not on target, peruse a few on youtube...

it is a manufacturing defect. Mine had it. My advice is to never buy polaroid tvs. but anyway, here is a link on how to fix the problem...

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!

i had the same problem. i opened the panel in the back of the tv (3 screws) and opened the aluminum panel (3 screws). there's a red led light located at the bottom left corner of the top board. to the right of the led light, you will find this thing with 4 switches. i turned the two bottom switches "burn" and "epmw" to on. so far tv have been working.

sounds like inverter board. What it sounds like is happing is your LCD is working ut the backligkt board that allows you to see is kicking off. (as you still have sound) Which could be the (most likely) inverter board, or the power supply board. You can take apart and check for voltage at your power supply. The power supply has a pigtail with large white wires and a connector. Power up with the center back cover off and check your voltage at the white connector on the power supply before and after the screen gos out. If there is no large voltage loss it is your inverter board.
You can used boards on e-bay or
