Hi,
I purchased a Triaxis and have been working through the many issues it has. I've quickly worked through the common faults. Now I'm onto more difficult issues.
The LDR1 & 2 on the main rear board are stuck permanently on - meaning the LED side is permanently powered. These are the loop bypass vactrols. The other loop Vactrols LDR3,4,5 are switching as expected.
I'm aware that unplugging the FxSend jack forces the loop bypass, but that isn't the issue here.
I've found the loop control switches transistor Q7. I also followed the related resistor and diode to the LDR1 & 2. Knowing how the main switching matrix works I've been looking for a capacitor shorting to ground on the diode cathode; but found nothing.
Any help on debugging the loop control would be much appreciated. A schematic for the loop control would be ideal.
Thanks,
Stu.
