I have a problem with a Hitachi KH-1190e that is only producing a soft white noise. However I did notice when I was testing the voltages if I bridge two tracks it starts working ok. I have attached a diagram to show which tracks I bridged.
I tested Q5 as near and got: (without bridging the tracks above)
B 1.098v spec says 1v
C 3.82v spec says 3.3v
E 0.80v spec says 0.35v
(I did have a previous fault which is fixed which turned out to be a shorted coil - I believe this is ok still as not getting the resistance value I was getting before).
I have attached the pcb track diagram with blue arrows showing the two tracks I bridged.

Thank you
