Chevy Blazer electrical instrument cluster fault
Hello and greetings from Finland 
I have in my desk Blazer instrument cluster and I'm trying to find out the problem and fix it by myself if only possible.
Pictures of PCB's
Only speedometer and trip displays and warning lights works, but 3 other panels on the side are totally blank.
Do you have information what is causing the fault?
I checked allready factory solderings by microscope and all jointings seemed to be (and no broken wirings etc.) okay thus of that I resoldered almost everything.
