DX7 no sound (i think it's not the Battery)

I get no sound on the DX7. Headphones and Volume out didn't work. The Battery have to be changed, but before i did a SysEx Dump for trying a few Preset Sounds. They are saved until i turn the DX7 off. I tried an initial Sound, without success. The local mode is on and the keys work. I also tried to play a track via midi.... nothing...

When i turn the volume up, the noise of the preamp will get a little bit louder. But that's all.

Anyone has an idea what might be the cause?

Have You changed the battery.
Data Will be garbish if the memory backup is gone.
I would change it and dump sounds to it via sysex
and try again to see if it had helped.

Cheers

I have the same problem. I just had the battery replaced, but that didn't solve the problem. Any help would be very much appreciated!

There is a relay on the output of the DX7, intended to mute it during power down. Mine occasionally fails to unmute on power on, so I'd suspect this. I keep meaning to replace mine, but haven’t been able to find a part number. You could probably get away with removing it and bridging the appropriate pins.
