Default PMMI display

Has anyone had the display on the horn control not work? It plays music, just no display, wondering if anyone has fixed this fault before.

Do the controls work? IE song up/down?
If so it could be the driver chip or the display. Both on the little board...
I have a hand drawn schematic somewhere that I did a while ago.

IIRC there is one on ebay, but they are proud of it!

HTH, Joe

Yes it plays music and the track selection works, not sure that the volume does.
