Check smal electrolytic capacitor in the primary power supply. If possible
with esr-meter.

Hi,

I have found a VCR (Grundig VS520) which is not functioning, i.e.
display does not lit. I want to try to fix it, but I can't find the
problem. Hopefully somebody can help me a little.

The unit seems to have power only at the power supply part. When the
VCR is given power nothing happens at first, but after a while a
soft ticking sound emerges from the power supply part. At the same
time, a coil located at the cassette transport part of the VCR starts
to move in and out (not fast nor slow). This coil connects to a
plastic lever.

Grtz, Arthur
