Yes, sounds like a power problem.  Date code 3409 shows it is 8 years
old now.

My opinion is they aren't bulging; I've seen fresh unused stock with
that degree of warp.  But a photograph from a lower angle may be
better.

Another thing to try is isolate one wire of the suspect capacitors
from the single sided PCB and measure ESR and capacitance using a
meter.  Helpful because it is easily reversible.

I'm no expert though.  I've tried servicing a television of the same
vintage, and never did find the problem.  I blew it up by accident
with an earthed test instrument and just gave up.  ;-)
