Getting inside a TV for the all too common reason, to divert the crappy internal speakers to something decent, ie larger for some bass, externally. 3 caps on the ps marked "G-LUX" 470uF, 10V gold and black all with
exactly the same degree of bulge. No problem with the TV. Google images shows none of that type. No other G-Lux examples on the boards to
compare with. They have the incised Y type of end to the cap.

While inside took some data, perhaps useful for someone sometime.

Lytic caps don't bulge by design. If they're bulging, they're going into failure.

To add to this poster's point, a couple of things; The third notch in the cap. is for
heat dissipation because these are less expensive, cheaply made caps. Also, the temperature co-efficient could be rated lower than what the circuit is designed for
(to assure low tolerance, higher likelihood of failure and making device outmoded).
I have seen many TV's with the 85 degree C caps working a lot better on 105 degree
C caps. I increased the temp coefficient to make the circuit more robust and dissipate
the heat. This made the TV l fixed more likely to last. Never had a customer complain.
