That sounds like one of mine?

I stumbled by the youtube video yesterday. I'm glad you found this place.

Velcome aboard. We are here to help.

Welcome to the Beoworld forum !

First things to check:
- Is correct and clean voltage reaching the processor ?
- Is the reset circuit working ?
- Replace capacitors on the processor board and preferably also the small ones in the power
supply area (a 22uf and some 10uF if I remember correctly).
If these things are alright, it's most likely the processor itself that has died.

I have a BM6500 currently on the bench that does not respond to remote commands. Data is reaching the
processor from the IR interface so it could be a similar case to the OP.

As Die_Bogener mentioned earlier in this thread, not all versions of the 8032 processor will
work in the BM6500 and NOS parts are getting scarce.
I am awaiting delivery of some nice old original Siemens processors that will hopefully work.

I know you are expert as we talked one year ago by ebay,and I have your contact yet.

I am thinking that there may be be a fault in the IR receiver or perhaps it's amplifier. I will try to isolate.

If it will play radio, you can put it in testmode.
Of course, there can also be an electronic fault in the Beomaster.

Dillen:

Thanks to a good friend, I now have the proper service manual and here
is the NVRAM reset procedure:

To enter Testmode, press "Radio" (on the MCP or Beolink 1000) and short 4TP1 briefly.
4TP1 is found at the solderside of the processor board, right behind the leftmost
of the two large connectors. Be careful not to short anything else.
Then press "7".
After about 5-6 seconds, the display should now read "88".

This will:
- erase stored FM/AM programmes
- set Bass/treble/balance/loudness to neutral
- set volume to 26
- set option to 1
- set clock date to 890101

To exit Testmode, press standby or pull the mains plug.

But my BM6500 does not respond to the remote!! I will have another look at it tomorrow.

I suppose it will wipe the timers as well? Good info.

Any chance of getting the service manual on site? The lack of proper manuals for these later models has annoyed me greatly...
