I was wondering if someone could help me with a recent purchase of a 909 that is having some strange issues with patterns…
When I turn on the 909 I’m getting very weird patterns that are added to the machine from 1-16 automatically and it’s a one big noisy mess. It happens every time when I turn power on. Then i have to clear the Patterns, and then I can start programming and it’s fine but if I turn it off and on again those bad patterns reappear again. I have no idea what to do, batteries have been changed to brand new and the unit was factory rebooted multiple times…
would replacing these 2 IC possibly help fix this?
IC TC5514APL-3 SRAM chip
IC TC5517APL static CMOS RAM
