I'm not familiar with modern TVs - any chance it uses a separate part of
the power supply to feed this tuner, and that has failed?

Quick Google suggests you are not the only one...

AFAICT it's a single 5v supply.
Might not be the tuner of course, it's only supplying differential
baseband IF, the problem could be in the next chip along...

It looks like its using a td1318af/ihp-3 tuner (pic of main board here
