Not sure if this will help, but most caps fail with the in rush of power, over and over. Sounds like they were not made right. You might try a UPS ( uninterrupted Power Supply) this may help you with dirty power from your power company. And with high spikes. Make sure you get one that will handle the TV current draw. As far as upping the CAPs keep the same or slightly high voltage and increase in uf. You might find one that has the same uf and a higher voltage rating that will handle it.
SOURCE: capacitor size
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
SOURCE: No longer turns on
It's well worth replacing the capacitors, but this problem can be caused by a short on the power supply (Which is what the caps do). Most shorts that arise in power supplies are result of a shot transistor or diode and of course the electro caps. Check these while your changing the caps.
Good luck with it.

If you have different TV do a search on the model number...
SOURCE: Which Replacement Power Board for LNT4665F Samsung LCD TV?
Howdy,
It would be a lot cheaper if you just replace the two caps that have gone bad. Just get a cheap solder pencil from the store and about an inch of solder and you are in business.
The Power Supply Board is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.
Thaks for using FIXYA, BIG IRISH.
SOURCE: I have a VP322 32" Plasma TV with bad capacitors
I just got off the phone with a Vizio rep - My VP322 also stopped powering on - 2 years and 2 days old. They are sending a repair person to fix the TV with NO charge to me. I had no problem with them, just called and told them what had happened (wouldnt power on), they took my information and informed me that they can authorize a courtesy repair for 1 year AFTER the warranty expires. They returned my call within 5 hours with the name of the company that will contact me to repair the TV in my house. I will let you know if they actually come through
