My P10 is wacko. Sometimes I turn it on it lights
up and acts like it wants to work but if I cycle the power nothing will light
except the tune LED as if it is in tune mode but doesn't time out. If I cycle
power something different may happen. I think the PCB3 board has issues would
anyone agree? All Power supplies are good with DVM but I see noise ripple on
supplies with .2 to .5V that seems high to me. It is not 60 cycle ripple but
very random noisy ripple. Not sure of best trouble shooting approach of this
board. My P10 shematic is freeby with poor zoom in ability. My P5 is better but
refernce designators and power supplies seem different. Anybody got a good
service manual or advice?
