You are right there Cipher. Total cost of our servicing with all needed and used parts would amount over 2000 euros. The machine is a economical total damage.

We have in the past purchased a new machine purely to be used for loan and parts due to it being more financially viable than buying single standalone parts.

Totally ridiculous, I feel your pain, been stuck in the same scenario with a PSU on a Venus that was 1200 EUR.

Looking in the parts manual it looks like there are two cables that run from the side PCB to the main one. Have you tried replacing those or testing them?

Not yet, and does not make sense. It's just a USB A/B and 15 pin wire harness cable from IPU to the Cheetah V1 operation panel unit. There is a lot of GND ,+5V and some other signal function, but I don't see a single signal line special for the Home Button Switch. The Home Button switch is not in the direct line to the IPU board. The PCB i/o board (with Home Button Switch) is connected to other 2 boards in the Cheetah panel.
