My polaroid tv has the blue on light but no picture or sound do i need to get a new tv or can it be fix

Here is what you need, its from the manual for your TV

my POlaroid 37" did same thing blue light stayed on no pic or sound was 2 electrolytic caps on power supply board took back off and they were noticably bulged at top radio shack sells these caps at $3 apiece fixed mine works like new saw a video on here how to do it

It can be the main board or the power supply, look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Please post back what you find

mine did that then it would not turn on after a couple of weeks, the blue light came on but no picture. I changed 2 caps and fixed everything. check out this website, http://plasmalcdtvrepair.rankwell.net/2009/03/lcd-tv-problem-polaroid-model-flm-3732.html

YOU PROBABLY HAVE A PROBLEM WITH THE POWER SUPPLY BOARD. DEFECTIVE CAPACITORS.

It sounds like it is the picture tube. The same thing just happened to me. The back of my television started smoking and then there was no picture.

Thanks very much for asking. This was the first time I've ever attempted something like this from a web-site. The fix posted helped me very much. For the cost of the 2 capacitors from Radio Shack and a cheap soldering gun I was able to fix the problem in about 30 minutes. The pictures were the key.

Thanks again,

Hello dougie49

I would first check the back-light and the inverter. usually these are what causes the problems in LCD displays. If the inverter is bad most likely the back-light will have problems. If you need to replace the back-light 9 time out of 10 you will require a new display element.

I hope this helps

Thank you,

Hey guys, I read the solution about replacing the 10v 1000muf caps in the power supply module. I was ready to throw the set out. I tore apart an old old old Jerrold 700 converter and found a couple of caps that were 1000muf. One was 26v and the other was 52v. Anyway, the set works great now and I now have a 37" LCD in my shop to watch the Leafs!!!!
Thanks for the advice.

Have had many of these in the shop, almost all have had a power supply problem, Capcitors blow and shut down the board. About half of these can be rpaired but the other half will need a new power supply
