virus A in Test Mode Loop

  • I just started up my 'virus A' after storing it for a few years and once powered on it goes in to this 'LED test' and 'KNOB test'?

    after following the whole ritual af pushing buttons and turning knobs it restarts and just goes back into this same mode

    anyone knows how to help here? I am stuck in this test loop

    cheers
