I am having trouble pinpointing the problem with my DX7 lcd display.
-It only displays blocks. So, i know its getting power.
-replaced display, but new one has same blocks.
-the synth sounds great.
-
After replacing battery I can load songs from a cartridge no problem.
-
it plays from cartridge
-All the connectors are secure and pass continuity between components.
- data slider works. i can operate the programming partially but i cant really see what values im changing. I successfully manipulated pitch wheel and mod wheel values.
-LED works fine. No weird characters.
-Tried the mini potentiometer near wiring connector, but only changes brightness.
I did as much research as i think i can, even looking for a seller of the 9.426 mhz crystal. I don’t think it’s that because it sounds and the LED isn’t scrambled
I could just use it with patches and navigate the features blindly, but i bought it to program.
Can it be a bad capacitor? Or something more complicated?
I only paid $100 for it plus the price of the battery and display. That brings it to $150 total.
