Hi, I've been trying to fix an old CD610 that initially wouldn't read discs.. After lots of cleaning and adjusting the laser current it now reads discs and plays them. However, as soon as I connect an amp or even my Picoscope ground lead the counting stops. I can listen through the headphone socket fine provided nothing is connected to any ground.
All the power supplies look fine although the 15V rails are only around 13V.
Does anyone have an idea of what I should look at next? Troubleshooting without a scope reference is a bit tricky.
Many thanks
Jon
