Got a problem with my PCM 1. Last time my battery was down, so i try to kickstart it with another battery. Unfortunately i changed the plus and minus connectors... 

Car is running, all the systems too. Except the PCM which is down. Black screen, no sound, no navigation actions (eg. cd read etc.).

Check out the main Fuse as well as the 10 amps fuse and the backside of the PCM. Also check out fail code with the FVD Brombacher System. No Failure code.

Did anyone got the same problem and solved it? 

Thx in advance

When you reversed polarity, you place every electronic system in the car at severe risk; they really don't take well to this.  It is entirely possible you have fried the PCM1.

Allready realised that fact... Question is: Did anyone got the same problem? Could you fix it? Is there a kind of restart ( like on PCM2)?
