The VCR does not switch on.
The VCR does a 'tick tick' every second from the power supply. The switching power supply has a TDK SRW2923 and a TFK U4614 regulator. Is there someone that could help me in order to understand the cause of the problem?
The power supply is labelled R3000 SMPS B.
Best Regards,
Guido
