Customer Question
I have a dx7...

I have a dx7 iifd that needs battery replacement. I have the battery and holder. I've removed the bottom and removed the 4 screws holding the main board in. How do I get the main board out? It seems stuck at the midi ports.

Technician's Assistant: What's the brand and model of your instrument?

Yamaha DX7 II fd

Technician's Assistant: How long has this been going on with your DX7? What have you tried so far?

I bought a batter (cheap) and a local retailer did it for me; however, the instrument will not hold programs. So, I assumed I had bought a cheap, dead battery. That was months ago.

Hi. Ive opened it and removed 3 screws on top of the main board (on which the battery resides) and removed the four screws on the back of the synth connecting to the board. Now I must lift and remove the board to get at the battery; however, it seems stuck on the end with the midi ports.

My questions are elementary but I've looked far and wide for answers without finding them. I've been given a Studiologic SL-880 by a friend. I've been trying and failing to get my computer to recognises MIDI messages sent by it. I've a Yamaha PSR-e535 keyboard, with sounds on board but MIDI enabled and trying to get sounds from this out of the computer persuades me that the problem lies with what I've got, or more likely not got on the latter. I've checked the USB cable from the Yamaha to the computer is okay. I've no reason to doubt the MIDI cables to M-Audio interface to USB from the Studiologic to be duff. … read more
