Hi. I tried here to read all about problems/solutions with beomaster 1900 whit the same issue but non ware as mine is.

The unit was bought as non runner with just the stand by light working when plugged in. When opened it up several old caps ware leaking and had cracks.

I recaped the whole thing whit Martins kit, and the rectifier as well. I tested the lamps and they all work I changed all three the fuses. And all I get is the stand by light. If per example FM or other buttons are bushed the stand by light flickers time when button is pressed but non reaction of the beomaster not even relay click. So for now im completely stuck whit it and do not know what could be the problem? 

 

Best regards
