Hello everyone

I’m working on a Beomaster 1900, when I turn it on it only turns on the STAND BY LED. When touching a pin to turn on a function (tape-phono-fm 1,2,3,4,and 5) it does not work, no relay click sounds.
The device does not come out of standby mode!!!!, I need help

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

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