Is it hooked up with HDMI cable?
If so try unplugging the HDMI cable and re plugging the cable in, sometimes those cables work loose and if they are not tight, it will cause your screen to flicker. Happens to my TV once in awhile.

There is not a good solution. If you read about the Polaroid 37" LCD HDTV, you have a problem and it's the same one that many of us have. According to Polaroid's service center, the control box needs to be replaced. Polaroid does not stand by this product. The company gives you a lot of lip service about how many they sell and how few problems they have - they're lying. The TV's should be recalled and I'd suggest you join many of us to demand it. Write BBB, write the company where you bought the TV, write any consumer group you can think of - Polaroid TV's are junk. Sorry you've got one. Sounded like a good deal and Polaroid used to manufacture quality - no more.

As stated by the previous expert the fault is clearly a lowering of value of a capacitor or in some cases an IC or semiconductor. You can use a heater to SIMULATE the board in different section when the set to put ON and confirm the right place to where you can checck to replace suspected capacitors.-- in TCON or worse the LCD itself.
