Now this is one I haven't seen (!) but we can make a start without a manual. Are there any voltages printed on the IF or tuner units? Sometimes there are, and they are helpful in this situation.

When it's not on a station, do you get white noise on picture and sound? If this is there and OK, then the tuner is suspect. If this is weak or non-existent, go for the I.F. Board. Very much like a BRC 1400/1500 chassis.

Hope this helps!

Cheers,

Steve P
