No light check power board it has power but no tv
The power board might have input power, but there might be no output power. Check and replace the main power regulator board.
You must have sound knowledge in electronics to follow me. Very sorry. I'm not a trainer. Contact any experienced service technician to make the set right, rather than spoiling it.

FLM-323B same problem, black screen. Checked out the power board and there is no 24v on it. Took the board out, let it cool off, put it back in. Got my TV back for a while, checked for 24v and it is there. Worked for a few weeks, now it's out again. Known issue with Polaroid, and if it's out of warranty, might as well throw it away because they WILL NOT help you. Personally this was my first and LAST POLAROID TV ever, TOTAL JUNK.

blown capacitors on the inverter/vga board replace them and you should be good.

Follow this link and read all comments/instructions. I have the Polaroid FLM 3732 37 inch and about a week ago this same problem occurred. I did not have the money to fix it, or get a new tv so I was pretty bummed. Then I found this site.

I am a single mom (girly girl) age 40 who has never done any kind of electronics work or soldering, but I was able to fix my TV following these directions and there is also a youtube tutorial for these exact problems.

I fixed it for under $30, and I am so proud and also earned some "street cred" with my 14 year old son!!
Polaroid is ripping people off left and right...it's disgusting but now I feel like I bucked the system for once!!

I do not know what your problem is as you do not even describe a problem, but I dare say capacitors do not need to be bulged to be deffective.
Usually the ones closest to heat source are the ones to dry first; bulging can be result of a too strong current running through them too and not neccessarily related to heat.
Usually they are large and close to the connectors that carry power from the power board to other internal boards.
Other capacitors may also be affected, of course.
You can try your luck replacing them in order, bring the TV to a specialist or start reading the theory of repairing SMPS - you can find it online, an excellent read if you really want to get into it.

usually capacitors are the problem on the TDA03211c power supply. 450v (volts) @ 10uf. change both. beside inverter filters.
