One more post tonight... I took a short break and was thinking over what I had tried. Then I reviewed suggestions from the Beoworld forum and came across some notes from early on. Dillen had mentioned that I needed to look out for the reset line (and there is a trimmer in that circuit too). I had measured that back when it was originally stuck in the

I figured out that the relay and circuit controlling the relay are just results of the problem. The relay turns the +50/-50 V supply off. So when the unit is in standby that power is not supplied...which makes sense. So as Olly was saying, the relay is controlled by the standby signal. I disconnected the relay. After adding test points to the 02 module

Module 11 is the Fuse and Relay board. The relay (RL1) on that board is what I am hearing, right Olly? It is controlled by a circuit on the O6 Modlue - Motor Control board which is marked as the uC Supply (+5v to the processor). I am getting ready to monitor those components. I did what you said and disconnected the connectors from the 09 Module (Output

I think a recap on yours would be pretty smooth. You have one that is working good already. The one I have was given to me along with a Beogram CDX for $25 ... with the understanding that the CDX had the hinge problem and that the Beomaster 6000 did not work. When I got it home and tested it on my dim bulb/variac tester the power came on and it was

You are referring to the Output Amp (09 Module), right? On that board I replaced the electrolytics and the trimmers for idle and offset. I'll start looking at the voltages there next. One of the original problems with this receiver when I got it was that it would play for a while then shutdown. The shutdown was such that it did not go into standby

Some additional information now...(I think this is going to take a while) I flipped the cover up and opened the back metal cover on the 02 microcomputer board. I attached a test lead to the +5V that supplies voltage to the counter chips. I turned the Beomaster on and it came up in "P" mode then clicked into standby mode. I couldn't get

I'm not out of the woods with this one yet. That's why I said I wasn't going to celebrate too much. I tested it playing some music for a bit more last night and the receiver would randomly go into standby mode. So something is unstable...and probably in the power supply I think. Remember when I adjusted the 6.5v output I decided to adjust

Reassembly and test I put a good part of the Beomaster 6000 back together tonight. Enough so that I could check some operations of actually using it. The power works and the receiver starts out in standby mode. The remote control works (first time to try that part). I decided not to use much power yet since I haven't adjusted the idle and offset

Just to be complete... I added the 02 Module part of the +5 VDC supply voltage circuitry to the simulator and measured everything again. The simulator also saw the 6.5V line out of the 16 Module drop. I figured that since I had the voltage readings for the circuitry without the 02 Module connected and was confused by it - that I would do one with it

Okay....maybe it is ready to work now!! (?) Going by the fact that the simulator pretty much matches the actual circuit when I make measurements and because I took out and measured the components involved on Module 16, decided to connect the 02 Module and keypad back up to the receiver....and it appears to work now. With it hooked up and working I now
