Do you have the necessary troubleshooting skills, test equipment, ability to read a schematic, know how to test components and soldering/desoldering abilities?

What DC voltage do you read "across" C810? (162)
What DC voltage do you read "across" C889? (19)
What DC voltage do you read "across" C884? (126) Remember this ground point, should be the same as tuner cover and is the ground that is used for all of the set except for Audio and primary of power supply.
What DC voltage do you read at F470 both sides (125)

This is how this works: I have the experience. You have a DVM. I specify what component (location number should be silk-screened on PCB) to measure/test. I even give expected reading. You shouldn't necessarily need a schematic (service manual easy to find ... with schematics, that's a little harder).
So let's see if you have raw B-Plus and/or switched mode power supply outputs.
