Description
Beomaster 4000 Repair:
A Bang and Olufsen BeoMaster 4000 repair. She doesn’t power up and blows an internal fuse.
The main capacitors serving the power supply and speakers have started to spill their insides.
Having been sat in an unfriendly environment for many years she is very poorly.
The insides are full of dust contamination and most screws heads have turned to rust.
The main power rectifier was also dead. The trimmer potentiometers were malfunctioning.
The front faders were very noisy.
The signal strength indicator lights were not working.
The signal strength meter light was not working.
The power on light was dead.
Mot a single wire to board connector in sight, and removing any part seems to require almost total disassembly of the entire unit.
