I took it all the way apart, all the power supply caps, and Q402 look like
they have been changed.

All the secondary power supply caps hardly have any dust on them, compared
to the rest of the board, and underneith the board, you can see where a tech
has resoldered a ****load of stuff on the secondaries of the power supply.

it probably came in as a dead set in the past.

So, the power supply looks to have been taken care of.
