Question about Polaroid FLM-3734B 37 in. LCD HDTV

6 Answers

TV won't turn on.

I have a FLM 3732 Polaroid 37" tv. It won't turn on. Sometimes when you unplug it and plug it back in, it will come on. When it does come on, it has a buzzing noise which goes away in a few minutes. Now the TV won't come on at all.

The YouTube video was correct solution for me, i went to Radioshack and bought two (2) 1000uF capacitors 35 wv part#272-1032. I already had all the soldering tools, i used a desoldering wick and my suction tool, the suction tool worked better. after installing the caps, put the board back into TV and turned it on.. all is well so far. i paid $3.44 for the parts. even if you have to buy a tube of solder, solder iron (15 watt max), and de-soldering tool it's still cheaper then repair shop and got nothing to lose even if you are a novice with soldering. :) Good Luck and thanks you guys for the lead on fixing my TV issue!!!

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:


1. If by chance the TV is still under warranty, go that route.

2. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

3. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

Go to youtube.com and type in polaroid 37 lcd hd tv repair. Two capacitators are bad. Get at Radio Shack for about.4.50. You can use the 45 watt. Fix yourself or get help to fix. Fixed mine easy. Very common prob with this mod.

Polaroid FLM 3732 No lights or anything


There are microchips theses days that can burn out easy on power boards. A large sturdy transformer could be used instead, in the design, but transformers cost big bux in comparison to microchips. Don't blame your TV manufacturer for using cheaper parts. They have a profit margin to maintain.
