Hi Chetan,

It's too hard to tell from the camera view.

Generally, if there is failure to be noticed, the top vent has and or=20
the bottom of the cap swells. But with electrolytic caps anything is=20
possible. I have seen side walls blow out!

Locate the audio amplifier, then it's power rails and put the scope on=20
and have a look.

Note: If you don't know how to do this safely, then don't. TV's have=20
lethal voltages, and bite bits!

It is difficult to tell some faults just by looking at the component=20
externally.

Sometimes smaller caps can be at fault, other times dry joints. Really=20
depends.

Not always the power supply is at fault either.
