Vintage Synth Repair

Hi,

I just got an MMT8 and it appears that something is wrong with the
screen. When I power up, all the LEDs and buttons seem to work
properly, the screen lights up but no characters are displayed. Is
there a constrast control somewhere? Does it need to be plugged into a
keyboard to display anything? Help!

Thanks,

Ian

awesome! It will be much appreciated!
