well, tapping on the neck board to get the picture back indicates to me
you've got a tube going bad, or bad solder joints on the neck board.
considering the amount of high voltage floating around there, i'd
suggest you fix that first.
A bad tube won't make snow, but I suppose there might be some strange
arrangement where power for the tuner routes through the neck board. More
likely the tapping is just jarring a loose connection inside the tuner, this
should be easy to fix by just resoldering the bad one.
He was talking about tapping the neck board solving a blank raster, not
the tuner problem. It certainly does sound like a bad tuner but I'd
check all the voltages first, if it's missing one it could cause this
problem, check the 'net for a datasheet and work from there.
