check for dry joints on the main pcb. also look for a little metal 2
legged can in the chroma decoder circuit (pal section - some models
also accept secam)) there should be a number containing 4.43 printed
on it.

Couldn't find the 4.43 can.

Found some brown stuff under two black-gray condensers in area labeled
"primary" under the same hood where the power inlet is on main pcb. Would it
be worth trying to replace these?

Also a component labeled "Sharp 12SZ11" seems to have been running hot.
