Past the limits of my troubleshooting ability on this issue.
On Monday, our main ICP 7800 was powered down after leaving it in standby over the weekend. Nothing happens at all when turning on the instrument with the on button in the front.
Figuring the most likely cause is a bad power supply, we swapped power supplies with our other 7800 and still nothing. Power feed was checked by our electrician and it is good.
How do I troubleshoot the power button on the front, or any other part to see if the instrument is getting the power it needs to just turn on?
