The PNA board seems like its fried, So I need to find a new PNA board for it. If anyone has a spare Working PNA board for the DX7 Email me : Scaleskit@gmail.com
The PNA is the board with only leds, switches, potentiometers and diodes.
So you can repair it I think.
Did this get solved? If not, I MIGHT have the part… I have a DX7 which took some physical abuse but still works and have been thinking of parting it out (vs keeping spares for my own…)
Hello 172pilot!
Welcome to this platform.
I have a DX7 which took some physical abuse but still works and have been thinking of parting it out
that is unfortunate. however if you do decide to parting it out, I’m sure there will be many users that will be interested. I myself am trying to repair my own DX7 but are unsuccessful so far.
(it might need a new transformer at this point…)
So keep us updated.
Kids regards,
Steven
Hey, have you decided to part your dx7? I am looking for a euro psu/transformer to buy.

Mine is a US DX7 so if “euro” means european, I probably can’t help…
