Paul I would check the 9-700 board for bad joints , in all the years that
I've worked on Zenith sets, the 9-700 board was the single board with the
most bad joints that I had ever repaired (almost 70 on a single board)

> This is one of those Zenith sets with the Bose audio and the 9-700 main
board made in1989. To my knowledge the board is no longer available. The
problem is the signal goes to snow intermittently.Loses picture and sound
is muted because of loss of signal. Also lower channels are snowy.This uses
a prescaler and ICs on board to tune, per the info that I have. All the
supply voltages and lytics are OK. Was wondering if anyone is familiar with
this chassis and problem.I didn't find anything in my Zenith data base that
was of any help. Could the prescaler be the culprit? Paul
