I bought this tv like 2 years ago. recently i insert the kettle lead cable into my Polaroid FLU-2631 and i get a ret light. after pressing the power button i hear a quick littel buzz from the psu and the red led turns blue. there is no image displayed and the tv stops responding. ive checked all the capcitors on the psu and they seem fine except a large one that has 25/105/U39 written on it. that one is bulging out from the top. also i am not getting any voltage output. using a tester i have checked all the 5v, 12v,and 24v. can someone help me out.

It definitely sounds like that capacitor has blown, you are going to unfortunately have to replace it. Luckily it sounds like you are probably technical enough to handle that on your own. Are you familiar with how to replace a capacitor? If not there are many tutorials if you google for it..

Thanks, please let me know

Polaroid FLU-2632 LCD TV full HD 2 HDMI problem


You could try pressing the source button on the remote to see if that brings it up.

Also the TV may have got itself in a muddle. There will be a way to reset it to factory setting. If you can get into the TV's setup menu there ought to be an option buried somewhere to do that.

Doesn't turn on


Pretty good chance the power supply board is bad. A number of capacitors will become leaky and you lose all power. Some techs still know how to do component Laval service but most just change the board $$$$
