How to extend the life of their daily driver?

[Airedale]

Zeno, a small and silent fan could be a good idea. Subtly added to the upper back to help exhaust.

Old_tv_nut, its just a plain jane, 27 inch, 1993 Magnavox. It's very low hours for its age as it was kept in a spare bedroom.

Maxhifi, I've got 5 good spare sets, I just want to see what can be done to extend its life.

I'm using a surge protector, have the brightness turned down. I like the idea of adding a discreet fan in the back. I've heard of the "soft start" circuit which sounds like a built in variac.
