Could be the key assigner cpu is not running at all. Check supply
voltages.
Also check the connector between the two boards, especially the RESET line.
If you have a multimeter, check the voltage on the reset pin of the key assigner cpu. It should be high.

Hello, I have a problem with my polysix. Klm366. All the Key assign mode lights are stuck on and no voices working. Should I check IC1 (74l505) ?
My klm367 board is tested and works correctly.
Any suggestions?
Thank you
