Hi! I’ve been trying to install the modypoly upgrade in my poly 61. However after putting the modypoly chip in and turning the synth on to see if it worked, i noticed something was off.
The display is stuck on P5 61 and the keys don’t produce any sound. The Joystick and arpeggiator seem fine though.
The previous owner replaced the bad battery so i don’t think the problem is due to corrosion but i’m not sure. I also slighty bent one of the pins on the mody poly chip when i was trying to install it but it looks okay now according to me,so i hope the problem is due to something else
Here are some pictures:
Do you have any ideas on what might have caused this?
This is the first synth mod i’m attempting, it would have been smarter to take it to a tech but i thought i would take a risk and try to fix it on my own
