Thank you for taking the time TK. It’s your answers to other forum posts that have helped me to get this far 🙂

I figured out the logic with AC and ACC commands. I only have a stand alone Beosystem, no other linked devices, so the AC commands works plenty. I was able to figure out all commands except turning off the device. The code you provided above works though, thank you. I’m using TV 0x80 as source instead of A.Aux 0x83, but it seems to work the same. This is just because i usually use the “TV” button on the Beolink 1000 that sends 0x80.

I do have a question about the ToADR. The Beomote github I linked to references these adresses:

SOURCE_VIDEO = 0x00,
SOURCE_AUDIO = 0x01,
SOURCE_VIDEOTAPE = 0x05,
SOURCE_ALL = 0x0F,
SOURCE_SPDEMO = 0x1D,
SOURCE_LIGHT = 0x1B

They seem to match better than the code for the selected source (radio, tape, cd etc.). It seems like the commands only works if I use 0x01 (Audio) or 0x0F (All) as ToADR. If I use 0x00 which is referenced as TV by Toresbos github it doesn’t work. Does this matter, or can I just stick with 0x01?

 

I don’t need to fully understand the OUTPUT data, but I would like my device to be able to read the Volume level and selected Source. I have set up RX functionality in my software, but I don’t know which bits to listen for. Would much appreciate some help 🙂

That way I can add a volume slider that takes the current setting into account instead of having to repeatedly press the “volume up” command. Also, I can set the software not to change to the TV source if I start the tv while playing music from the Beogram or something.

PROBLEM SOLVED:

I was about to give up, but as a last desperate attempt I removed the RAFOC-unit. I didn’t wanna do this at first since I didn’t wanna mess with the angle setting.

Anyway, after removing it, cleaning it, and dipping the two bearing balls in silicone oil it works like a charm!

Thank you so much for your suggestions and help Die Bogener and Dillen.

The search continues…

It works more or less reliably in vertical positions.

I found one video with the same problem, but he just replaced the focus unit.

I removed and cleaned all ribbon cable connections, also ohm-measured from the servo board to the solder points on the swing arm with good results.

I tried to remove the clamp  – same problem.

It’s not a issue with the Disc drive motor. In service mode 3 the disc spins perfect and quietly regardless of how and where i push/move/angle the unit.

The noise must come from the swing arm/laser.

I just can’t see what possibly could be effected by pushing the back of the unit down, nothing seems to touch anything, and the swing arm moves without friction either way.

I just did some more troubleshooting,

The tracking force seems to be right, 1,19g (measured with a jewelers scale).

It randomly skips/repeats the groove, maybe every 20-30 seconds. I can’t see any obvious reason why and the tonearm seems parallel to the sensor arm the whole time, even when it skips.

New problem: Twice now it stops playing by itself and resets the arm and turns the beomaster to standby. First time after 3min and second time after 10 min.
