Help, I need circuit diagrams or service manual for a DX7II. The power supply has failed. I can probably fix it if I can get the circuit diagram !!!Anybody ?

Hi Eddie:
I have DX7 IIfD, and I had the same problem,it turned out to be the Battery,

Thanks for your reply.

I have managed to fix it. It actually was the power supply. A single chip bridge rectifier had blown.

I have heard about the battery thing and I guess I am going to have to change it, but at the moment I am up and running.

ITEM CLOSED

Hi Eddie:
Glad to know that your are OK,I need to ask you if you have strings sounds or full brass .,Thanks......Hady
