Hi all!
I need a service manual for Electrocompaniet Rena s-1. who can help?
sound disappears from the coaxial output. if you touch the case with your hand, it appears.
I contacted the dealer in my region, but they could not help me. A local service can help, but a service manual is needed.

Broken contact or bad soldering on the connector.

Thanks for the answer. The whole problem was in the non-original power supply. The power supply selected according to all parameters solved the problem.
