Anyone work on commercial-type machines? I have a Franke FM850 and get a goofy error every time we lose power.

Every time the power goes out our machine (Franke FM850) goes into a state where it will start to boot up, but in the middle of the FRANKE screen with a loading graphic, the screen just goes dark.

The first time it happened a tech brought it back to life. The second time I did after fiddling with stuff for a while.

This time nothing is getting it to work, and the tech said that it needs a new operator panel and quoted over $7,000, which is insane for an older machine.

Any ideas? I'm handy and not afraid to get my hands dirty in the electronics.

Thanks.
