Sony KV 1212
B+ from the line power supply is there but that's about it. No sound No HV No antything (well the neon light comes on but that is about it.
I assume the LV supply is from the flyback, there is voltage at the collector of the fly but nothing at the base. I have not scoped it, but I assume its not getting a drive signal. I am a little out of my comfort zone on this one as I mostly only work on old tube style sets. Any hints on where to go to trace down the problem? |
