sounds about right, most caps the cover was shrinking due to overheating,
the one today was a 1000uf ar 10 volts, the top wrap was sightly pulling
away.
The screen had not totally failed but had a 60hrz ripple running to to
bottom. most of the caps looked good but I changed all the output, isolated
side to be safe.
Screen looks great now

Were these capacitors visibly bulging on top? The story goes that a few
years ago, a cap provider in China got their mix wrong for the dielectric,
and tens of thousands (maybe more) of these caps got put in all kinds of
devices. They didn't fail immediately, but a well after the warranty had
run out.

Dont throw away those flat screens when they die.
I fixed one today, 30 minutes and 5 capacitors on the output power
supply.
They seem to be made with under rated caps. So far since last year i've
fixed 9 flat screen monitors, all capacitors in the output power supply.
I've change the caps but up'd the rated voltage on each so if it 470uf
10v, i put in a 470uf at 25v.
Easier than fixing tube monitors, takes about 30 minutes. Nice side job
in the future, everyone will have a couple.
