I also have a Tv that's pushing 10 years old, a plaine no frills Samsung. The caps on the power board went bad on it already, so I purchased a recap kit on Amazon and fixed it. Right now money is tight, so the closest thing

How did you determine it was the caps on the power board that went bad?

Generally, you can identify bad capacitors (at least the "barrel"
kind) by them being swollen up (especially on the top surface)
and/or leaking brown gooey stuff.

Quite common on power supplies and motherboards.

I googled the model and symptoms, and I wasn't the only person having the
same issue. Also due to the age of the TV, it was made in a period when a bunch of bad capacitors were being made. One article explained the voltage rat ings were barely sufficient and would cause caps to fail. Some looked
swollen, but others showed no visible sign unless they were unsoldered and checked with a VOM. The kit included every cap from the power board, and
were of a much higher grade and better voltage ratings.

I was given a couple of dead LCD computer displays because they wouldn't power
up, and I was able to fix them all by looking for bulged or leaking
capacitors on the power board. I have also witnessed bad caps on pc motherboards that swelled up and leaked.

Ah, I did that one time.. I had a DVD player that stopped working and Googled it, and someone said there was a capacitor in that model of player that was known for going bad. I replaced it, and sure enough, it worked again.

I was curious how they determined it was the capacitor. I don't remember if it looked particularly bloated or anything..

There was a rash of bad capacitors coming out of Asia roughly between 2002
and 2006. The story I heard was one manufacturer made a change to save
money, and through industrial espionage, several other companies also made
the change in their electrolytic formula. In the following 4 or 5 years, cap failure was a common thing. Even in older electronics, capacitors
have been known to dry up over time. Many older Mac models have leaky capacitors, and if they are not replaced or cleaned up, the chemical could destroy the traces on the boards, making them un restorable.
