Dometic 2000w inverter stuck in boot loop

Hello i have a problem with my 12vdc/230vac inverter

It trying to start but after some seconds it turns of and tries to start again.

I have no voltage drop on the input. The four big capacitators only charges up to 200vdc

I have tested the mosfets and they are OK!

I have measured the pins on Pic PIC16F886 and ka7500bs. I struggle with the values and needs som help to keep going.

Pin measurement on ka7500bs

1-   5 V appeares when starting but then dissapears.
2-   5v
3-   3.6v appeares when starting but then dissapears.
4-  5v dissappear when trying to start
5-  1.4v
6-  3.4v
7-   0v
8-  11v



16-  5v
15-  3.9v appeares when starting but then dissapears.
14-  4.9v
13-  4.9v
12-  11v
11-  11v
10- 1.9v appeares when starting but then dissapears.
09- 1.9v appeares when starting but then dissapears.
