Microprocessor board? Do you know history of this unit?

I’ve seen a few times parts from different types in one unit ( someone bought on ebay ),

then you can expect everything ...

Hi 

I trade that unit for some BL 6000 speakers.

it's all MK3 not mix mk1,2 and 3. I did check all components.

Are you sure it's Microprocessor board ?

If i do test for Microprocessor all is ok no error ..hmmm

Based on what you have said it sounds like the pin code has not been accepted or written into memory.

How exactly did you enter the pin code? It should be entered by doing the following:-

  • The service code must be entered when a source is selected and the product asks for the PIN-code “PIN _ _ _ _” press down the "down" button on the keyboard for three seconds and the display now writes “PIN _ _ _ _ _”, press the "up" and "down" buttons on the Keyboard to select digit, press OK on the Keyboard to accept digit.
The same procedure is used for the mastercode
