Dear forum,
I have two Pentas connected to an Avant using daisy chaining. The one that is daisy chained turns the display off when on standy-by but the backlight somehow stays on. The other Penta speaker, which is directly connected to the Avant, does everything as it's supposed to. Yesterday both were still working correctly. I was trying to figure out whether there is a dimming function in the Pentas using a flashlight (torch light) and now that problem has occurred... Help please.
Greetings,
Kai
Unplugging and re-plugging powerlink has solved the problem for now. Pretty much like the Microsoft method. Hope that it doesn't re-occur. Does anybody have an idea what might have caused the fault? Does it have to do something with me putting the display under direct flashlight (torch light) in a darkened room to test whether the light sensor is working correctly? Or is there another cause like the way the speakers have initially been connected?
No idea what the reason might have been? Seems to work alright now. Was still strange though...
Rgds,
Unfortunately, the problem apparently isn't solved. When I got in the morning today, the backlight of one speaker display was on again. After turning on the main lights in the room, it turned off. Strange.
Greetings!
Re-flow the solder joints around TR4-TR8 and the LDR on PCB 24. PCB 24 must be separated from display and processor-board, if not ESD precautions must be made. Be careful with the connectors as the traces break easily around them when disassemble/assemble the boards.
OR... just leave it as it is. It will not affect the sound or the function of the speaker.
//Bo.A long list...
Thanks Bo. I won't be able to do that myself. Damn. I get a feeling that it's only reasonable to own vintage or close to vintage B&O stuff if you're able to do electronic work yourself. Seems to be very hard to get fully operational devices...
Is removing the displays simple and without much risk or is it a fiddly task?
