OK now id'd my problem board 3 the microprocessor board pt no  8001032 has a problem somewhere in it/on it.

It will boot up, the display showing source info etc but no volume, just the normal 2 dashes as if muted(the relay on the amp board also does not trigger - are these related

Another problem the unrepaired display will light up ie backlight but no source info, so need one of these also(I think)- orange display

Anyone out there please contact either by pm or thro'here!

Hi Tony

I did a repair to one of those amplifiers a few years ago. The display was just lit but no text on it. The cause of this was on the small PCB (3x3 cm) at the input connector. The soldering of the data pin was bad so the cpu didnt know what to display.
