BeoSound MK III, CD sledge moving very slow
in BeoSound · Aug 22, 2026 08:51Sure. In my case the slower movement of the CD-sledge had to do with ‘the system thinking’ that the glassdoor isn’t closed. If the system concludes that, it forces to slower sledge speed as a protection (cause if fingers…

in General Discussion & Questions · Aug 20, 2026 09:25Ik zou het vriendelijk formuleren, maar hem wel adviseren om vóór een volledige recap eerst nog een paar gerichte metingen te doen. That is good news regarding the original CD problem, but I would personally hesitate bef…

in General Discussion & Questions · Jul 15, 2026 11:40This is actually a very significant new observation. The behaviour has changed from: “the sound disappears after some time” to: “there is no sound at first, but if I let the CD continue playing, the sound appears after a…

in General Discussion & Questions · Jul 10, 2026 16:43Thank you for the update. Actually, I think this gives us another important clue. The fact that you were able to play two complete CDs without any problems strongly suggests that the laser and CD mechanism are fundamenta…

in General Discussion & Questions · Jul 8, 2026 13:23Thank you, that is important information. I also have another thought. A worn laser in a Beosound 9000 usually causes problems reading the disc itself. In that case, you would typically expect symptoms such as difficulty…

in General Discussion & Questions · Jul 7, 2026 16:56That is an interesting observation, but I am not yet convinced that it is directly related to the CD audio problem. To me, it sounds more like a separate issue involving the sledge positioning or calibration. If TM71 alw…

in General Discussion & Questions · Jul 7, 2026 15:21Sorry to hear that Edo. The new symptoms actually make the diagnosis even more interesting. The fact that: the CD spins correctly, the counter advances normally, radio always works, and sometimes switching to Radio first…
What is this part?
in General Discussion & Questions · Jul 6, 2026 13:11I do not recognitie it as a B&O part, but it might still be one. Looks to me as something that is to be pushed in some kind of frame (with the 4 upstanding feet). And keep two cables/wires apart from each other on both s…

in General Discussion & Questions · Jun 25, 2026 11:43That is excellent news! Congratulations on finding the real fault. This has turned out to be a very interesting troubleshooting case. In hindsight, the LF33CDT explains many of the symptoms. A regulator can become therma…

in General Discussion & Questions · Jun 6, 2026 10:44Thanks for sharing again Edo. This is actually the most promising clue so far. What caught my attention is that cooling the LF33CDT does not just bring the sound back temporarily, but appears to extend the operating time…

8000 MK1 speaker "fried" pls help test
in General Discussion & Questions · Jun 3, 2026 12:54Thank you, the photos help understanding. A few things are still unclear to me: During your test with the Pioneer headphone output, approximately where was the volume control set? Very low, medium, or normal listening le…
8000 MK1 speaker "fried" pls help test
in General Discussion & Questions · Jun 3, 2026 10:27Hi Christian, One important question that may help us narrow this down: How exactly are you testing the speaker? Are you using: PowerLink from a B&O source? The RCA input? Something else? You mentioned that the LED turns…
8000 MK1 speaker "fried" pls help test
in General Discussion & Questions · Jun 3, 2026 08:38Thanks Christian, for posting the photos. I don't immediately see any obviously burnt components, damaged tracks or leaking capacitors, which is hopeful. Before measuring anything complicated, can you tell us exactly wha…
8000 MK1 speaker "fried" pls help test
in General Discussion & Questions · Jun 2, 2026 16:05Hi Christian, The fact that the red LED still comes on is actually encouraging. If the main fuse had completely blown, I would normally expect the speaker to be completely dead. Since the speaker was accidentally connect…

in General Discussion & Questions · Jun 2, 2026 15:40I would not worry too much about the 4-layer PCB at this stage. Yes, an internal track or via failure is possible on a multilayer board, but based on the symptoms I do not think it is the most likely explanation yet. The…

in General Discussion & Questions · Jun 2, 2026 07:50Hi Edo, thanks for your update. I actually think this is progress. The fact that replacing the TDA1305T did not change the behaviour strongly suggests that the DAC itself was not the root cause. What I find more interest…
