it's already the second time my digital instrument cluster stoped displaying the tachometer & information center section: A couple of months ago, several lines of the dot-matrix display died out, and another two weeks later, the whole section together with the RPM scale and the INFORMATION CENTER caption remained dark. In the car repair center, which always repairs my car, they only told me that I should disassemble the cluster, look for faulty solderings, and re-solder them. I did that, but a thorough inspection with magnifier & multimeter showed nothing broken.
Is it possible that one of the ICs on the PCB or the heating filaments in the display itself are dead? Of course, I could order another cluster, but freight rates have become astronomical.
