Sure- that's the maximum rating. In fact, if Polaroid had used 35v rated caps in the first place, we probably wouldn't all be replacing them.
BTW another replacement that worked perfectly here.

You can get any size/type capacitor from DigiKey. See this thread for the part numbers I used: http://www.fixya.com/support/r741402-polaroid_flm_373b_lcd_tv_black_screen

This kind of failure is very common; that is why I suggest that one should keep the old CRT TV, buy a converter and put them both in the garage or basement so they are handy when our s*e*x*y new sets go belly up.
With fair confidence I can say that the main power supply has failed.
If you want to try this on your own, it only will require the removal of a few screws and a flashlight.
- Unplug the set overnight. - Remove the rear housing - Use some logic and these tips; look for a separate board with larger than average parts on it and seems closer to the power cord than others. This will be the power supply.
Check the board over for something that looks like a part number and record it. If you find more than one, one of them will be the bare board number, the second (sometimes on a sticker instead of printed directly on the board) should be the part number for the assembly.
Search for the Westinghouse service company nearest you and call them with this info. Ask if they repair these or just sell new ones. If it is the latter, don't pitch the old one, continue to look for a repair service that will take it on after you have the new one in place and can watch your favorites again. The new supply will likely cost between $90 - $150 and with a little common sense, most anyone can remove and replace these in the set. Expect any repair to cost about the same as a new supply; US technical labor costs more than Chinese assembly labor.
These supplies can be as reliable as the primitive older type but companies refuse to use the high-grade components necessary to give them a long life so they fail much sooner than the old, less efficient kind known as 'linear' supplies.

SOURCE: INSIGNIA LCD won't turn on
replace 2 condensers in the power supply with greater voltage ones.original are 1000uf 35volt...use 1000uf 65volt...99cents each
power circuit is made to fail with typical tv industry tactics...the warranty is reflected by the life of their condensors (capacitors) average life is 2000 hours..
if your a smoker...you must clean the button cover as they get stuck on with your stupid tobacco residue. 75% of all LCD tv's that smokers own fail this way...
TRY TO STOP SMOKING...

Not all power supply used 3300uf/10v, it can have many many values, he was using generic term for typical value.
You should get the service manual for this TV first. You then need to do some voltage checking. Please read and undertand some basic how the LCD flat panel TV works so you will get some unsderstbding how it works.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:
