If the tuner is a 175-2264... few problems with those. The 9-700
was/is notorious for loose connections.. as the IC's plug in. What we did
was remove IC's and clean with pencel eraser. That could correct your tuning
problem also.. If your tuner is bad I may have one laying around. It is part
of the 700 module.. On another note.. There are two filters on the Bose
power supply that when they fail...will send high DC voltage to the Bose Amp
destroying the amp and frying the front speakers..If you need more info on
that let me know and i will try to find my notes.

> 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
