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

Correct. 'Bob Villa' apparently wants repeat business as his high ESR
caps will fail quickly. Note, 'Bob', good quality low ESR caps aren't
real expensive - you just aren't going to buy them at Radio Shack or
Caps R Us.
