Yamaha SY77 error on boot

Post by reaperc89 » Sun May 31, 2020 9:48 pm

I've just picked up a Yamaha SY77 that I knew was broken before I got it. The synth powers on just fine, but throws up some jumbled characters and then an error on boot. I was unable to enter the testing mode in this situation.

I opened it up and looked around, the fuses were all fine, and I noticed no obvious signs of damage on either the DM1 or DM2 boards. No loose cables as far as I saw, and the battery tested out fine at 3V. I wouldn't expect this sort of issue just from a dead battery.

Anyone run into something similar to this before and have recommendations? I've attached images of the boot flow to demonstrate what I'm seeing.
