Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

You can try contacting this guy to see when he will have it instock again: http://www.shopjimmy.com/catalogsearch/result/index/?q=Polaroid+TDA-03211C+&limit=50

Replacing the LCD panel in any TV is not a cost efficient choice for the average person. The cost of the LCD panel is usually as much or more than the TV is worth, often times costing as much as a brand new TV. Considering the poor reputation for service that Polaroid had before it went bankrupt, it is best you consider another option since the screen is only one part of what makes the TV. Even if you were to replace the screen, you still would have a TV that was out of warranty without any service support if another part fails.

I have a 3 year old TV with the same problem as shema_ross.

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.
