Digital instrument cluster trouble: Dot matrix field (tachometer + information center) partially dead.

Postby Trofeo1987 » Tue Oct 01, 2019 1:37 pm

Hello,

for a couple of days I've got a strange issue with the digital instrument cluster of my 1987-issue Troféo: The dot-matrix field in the lower central part of the cluster dubbing as tachometer and information center has partially died. See this picture:

Not only most lines of the dot matrix are gone, but also the text Information Center and all the RPM values (0…60). Is it possible that the heating of the corresponding cathodes has died or simply lost contact (due to a broken soldering point maybe)? And: Is it possible to repair this flaw, or will I have to buy another cluster?

Thank you for your hints.

OK, I bought a (second-hand) spare cluster and installed it. Not I've got a faulty one in my shelf.
