Hi all, my beomaster 5000 (Mod. 1983) does not turn on anymore. The red LED is on, the relays are tripping but if I press the power button it does not turn on. Then if I press the fm tuning button on the control panel it turns on. I have changed almost all the capacitors and also those on the display board without results. I also have another BM 5000 with the same problem. I think it is a common problem. Can anyone help me? Help meee ...
