This is common to almost all flat panel power supplies. There are 4
electrolytic capacitors (same physical size) on the switching PS.
There are 2) 1000uF X 10V and 2) 470uF X 15V that usually bulge and/or
fail. You shouldn't pay more than .25to .50c for each. (I used higher
voltage on the replacements of 1000x15 and 470x25)
Symptoms of failure a slow power-up or totally dead.

Look for highest ripple current rating. Nichicon HZ, HN, Panasonic FM

Going to a higher voltage usually raises the initial ESR. That kind
of defeats the purpose of repairing the equipment.
