Pulse Width Modulation Controls not functioning

Pulse Width Modulation Controls not functioning

2009-05-06 by synthromey

Greetings all,
The pulse width modulation controls on layer two of my CS80 are not functioning. The memory panel PWM sliders also do not work for Mem# 2 & 4. It seems like when I open the top it starts to work again though. Thought it might be a frayed or loose wire, but that doesn't make sense considering the Memory's 2 & 4 not functioning too. Can anyone tell me what they think it might be and if it's a circuit board, which one to start with. Thanks
