quattttro: Have you made any more progress? I revisited my BM6000 that doesn’t power-up properly. I was able get it to work with a known working good CPU from another BM6000. Now I’m very confident that the original CPU is bad. With the bad CPU, I observe two different (pseudo-random) behaviours when I plug-in the receiver. The first is a “:.” display, the second is a “.” display with the main amp rail relay kicking in. Glitch
No progress. Sits on my workbench, haunting me. I’m pretty sure mine has the same problem though, a faulty CPU. It is consistently unresponsive “.:”, & the main amp relay never kicks on unless I mess with the startup timing. Shame to turn it into a parts unit, but not much choice.
