Hello,
I am working on a Beomaster 1900 and when I power up the equipment, only the standby light comes on, and the relay click is not heard. What should I check or replace to solve the problem?

No relay click when you select a source?
Front panel correctly fitted? - If the bronze forks under the front panel does not grip
each their little pin on the circuit board, the touch fields will not work.

Hello Martín Thank you very much for your response, the device only keeps the Stand by LED on, I cannot select any source. The front panel is not installed. Greetings and thank you very much for your help

Check the switching ICs. Power and shorts (oxidation on pins).

Hi
I have the exact same problem. So Martin how do I clean the pins for oxidations?

I use a "glass-hair"/fiber brush.
But if there is oxidation, you can clearly see it as black flakes.
