Hello everyone,

I have a Trumatic 500 from 1999 with controller Bosch CC220 N. The problem is “when switch on the power the module PS100 doesn’t get ready and the monitor screen doesn’t start. To get the PS100 and Monitor on, we have to keep the power on for a few minutes, put off and try again. It takes two or more trails to start the machine. I replaced the batteries, one 4.5 v for the RAM and the other 3.6v in the power supply.
I have no real experience with this controller, any advice will be appreciated .
