Beomaster 5000
20th August 2008
No response to either the small remote control or the Master Control Panel was the fault with this Beomaster. The voltages around the IR amplifier chip 9IC1 seemed normal and a replacement failed to provide a cure. Further checks showed that the +34V supply was low at around 12V and had a lot of ripple on it. 2C8, hidden behind the mains transformer, was open circuit. [Beomaster 5000]
