Hello dear Members

I know it's about the Million Times asked for the Co.de for a Beocenter 9500

 

With a new Lithium Battery tested.

I've read already to:

Plug in the Center

Type 1271 with Beolink 1000 or Beolink 4

Unplug the Unit and plug in after about 3 seconds.

So far so good but it does not work this time.

Tested other Codes like 1270, 1207

Have already tested several BL 1000 and BL 4, no succsess.

Checked already the IR Signal to uPc board IC3 PIN 3 > Ok, signal clear present. Measured with Oszillscope.

What can cause this behaviour?

Hope to get an answer or a solution for that Problem.

Kind regards

Christian

It's a long time since I have done this, but I seem to recall that leaving it at standby for a hour or so before trying the Code procedure may help.  It's not logical but perhaps the unit gets used to the new battery?

Hi

J6st came back from a short journey where I bought a used BC 9500 for a couple of €'s

Took me 2 hours, the dead Beocenter was unplugged from the mains so long.

Tried once more the " code routine" but nothing happens.

So I swapped out the uPc- board (No 40)

Beocenter runs.

Put the old EEPROM into the "new" uPc board,

Beocenter runs.

Put back the old uPc board and tried both EEPROM's

Beocenter is not working.

So there must be a issue with the uPc board. Never thouhgt about this, never had problems with these.

To be continued....

 

Kind regards

Christian

Bad news....

For some saftey reasons I put in a new battery, now both uPc boards have the same behaviour, even I swap the EEPROM's.

Co.de is displayed and nothig there to get rid of this.

 

Oh dear what have I done wrong?

Hi there

Really no one?

Does anybody know about different Codes maybe for older models?

Have already found the usual 1271 and 1207 both did not work 😢

Maybe renew the 8 PIN static RAM?

Any help would be appreceated.

Thanks a lot.

Kind regards

Take out the battery again.
Leave it overnight.
Fit the battery and try again.
