Grundig VCR non-functional
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 |

Check smal electrolytic capacitor in the primary power supply. If possible
with esr-meter. Greetings PP "Arthur Rinkel" schreef in bericht ... Hi, I have found a VCR (Grundig VS520) which is not functioning, i.e. display does not lit.

(PSU pulses). Check C1045 (47uF/10V) on PSU sub panel
and if you mean the relay by "plastic coil" then it is C420 = 100 uF 25V in supply unit. regards gary -- __________________________________________________ _____________ e-Mail security scan by Symantec Norton Antivirus 2004 successfully completed.

I've replaced the cap. and it fixed the recorder ;-) I.e., electrically it's working, but now the child-lock is in place. According to Google this can be unlocked with a universal code. I'm curious though, what is the function of C420 in the PSU? Anyway, many thanks for your help. Grtz, Arthur |
