VCR Telefunken 2931E power supply / regulator board
Hello,

My son found a good looking old TELEFUNKEN 2931E to the near trash bin.
I didn't want to throw it away, so I decided to test it. Unfortunately, it turned out to be a problem - the power supply part does not work, and there are traces of а previous interventions.

On the regulator board, near transformer.



I managed to find sort of manual, but its different to this particular model. There are some difference in regulator board, where the main problem is located.

Can someone help me finding a service manual for this VCR?

Thanks a lot!
Kalin
