The blue is an indication that there is a loss of video signal. Since the set appears to trecover after a "warm up" period, it suggests that there are either poor connections or defective components inside that are effected by heat. Most components inside are surface mounted and not typical DIY accessable. Your best bet is to see if you can find a pattern to when the set works and when it has trouble. In other words, does the set take longer to start if the room temp is cooler? If the set has been on for a while and you shut it off, can you restart it right away or do you need to go through the "warm up" period again?

The details requested above will help a servicer track down the problem for you.

Hope this helps,
Dan

Hi my name is Roety,
I can help you with your issue ,
 
Polaroid went bankrupt, but you can still buy the mainboard assembly.
It costs about $200- $400 search on ebay or google using the part number on the main section in the middle rear or set.
It is held in with three screws.

When I turn on my tv, I get a black screen that says unusable signal. I change the channel, same thing. I try to use the DVD player or another add on and it is still black. My TV is an RCA 37in flat s


Take the back panel off and look for a smd fuse with an F on it. Middle panel in the upper left corner, it is about the size of a tip of a pen. We used a copper wire to make a jumper. Works great now!!! We also noticed that there we some loose pieces and we pushed them back in and now the buttons on the side of the TV work.

Polaroid 37 in LCD TV


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.

It doesn't have a bulb. LCD type TV's ought to be the most reliable type, but these Polaroids all have early failures of the power supply. Only way to fix it is to replace the whole electronic module. Call Polaroid cust. service and be persistant because they are used to abuse from angry customers.
Good Luck
