man lowered heater resistor to give better color and after sometimes
the power circuit has a burst and it now won't start. i want to
separate and use its channel tuner. anybody know how much volt i have
to give to power that section and where? thanks

 

You cannot separate the tuner unit and use it. There is also the IF module,
and then the video and audio detector and processing. These circuits are all
controlled with a microprocessor that follows a firmware program. The way
it is designed, what you want to do is very complex and expensive. A simple
solution is to buy a TV tuner receiver, or get a VCR to use as a TV tuner.
