Hello!

I need a functional uPH8 microcomputer printed circuit board (PCB) from a Beosound 3000 or a Beosystem 2 or a Beovison Avant or Beovision 5 or any other B&O device that uses this processor board. This board is called PCB 06 in the Beosystem and Beovision and PCB3 in the Beosound service manuals.

On the back side the PCB has the code B6143024 ver D

Isn't that the one with the anti-theft code in it ?
May I ask what is wrong with the one you have ?

Hello!

It is the one from the Beosystem 2 I bought on e-bay and that didn't work (almost) at all.

http://forum.beoworld.org/forums/t/25636.aspx

I used the PCB from my Beosound 3000 and the firmware and eeprom from the Beosystem 2 and Beosystem 2 started without a problem.

I used the PCB from the Beosystem 2 in the Beosound 3000 (swapping firmware and settings eeprom again) and Beosound 3000 doesn't start (not even the RED Standby Led).

It is obvious that the microcomputer board is defective. It might be just a pin on the connector or a bad solder joint, or it could be a part of the microcontroller (H8/3002) that doesn't work.

I am guessing at the moment that it might be a problem with the infrared pin on the microcontroller (I'll check tomorrow) because the Beosystem 2 reads the settings eeprom, cycles a relay once and then does nothing. If I remove the settings eeprom it keeps cycling the relay. So parts of the board work but not all.

Anyway, I'm waiting for an answer from my B&O dealer, but so far it was not very helpful.

One of my worries is that the Dealer will tell me that I have to replace the whole PCB 14 in the Beosystem 2 as the microcomputer board is soldered to the AVS (PCB 14) board. This AVS board will be much more expensive than the same board from the Beosound 3000.

PS: do you work at B&O?

Hello Andrei,

I read your post about the service suitcase in the B&O shop and I just had to reply.

I run an authorised B&O service centre and I find this type of behaviour ... well rude..

In our service centre we order the service suitcase and only charge for the defective parts. And when were done repairing we send the service suitcase back to B&O. Usually within a couple of days. We get the invoice and the credit right after one and another..

So that they charge you for something they dont ever pay for is a bit strange.. But each B&O shop/service centre is selfemployed. I gues that they are very orientated about not wanting to risk loosing any  money that they will loose some cutomers along the way..

Hello!

Can I send you the defective part and have it serviced in your service center?

Andrei

Hello again!

My dealer forwarded a reply from BeoCare that says you cannot get that module, just the whole chasis.

Can anyone confirm the price for 8006797? My dealer quoted me for over 600 Euro.

Regards,
Andrei

600 euro seems a bit overpriced but in the end the service centre sets the price..

I have fixed the board.

The ST24C02 serial eeprom (the one with the PIN security system) was corrupted and I managed to rebuild the information in it.

I think that mains power failed at exactly the same time as the CPU was writing a new PIN code in the eeprom or a timestamp and the CPU wrote only part of the data.

Andrei
