Half of the lights in my instrasument cluster is off

So I checked the PCB and it looks fine. Also tried with a different instrument and same problem.

So if the blue and yellow plug have their own ground, maybe this could be the culprit?

But does both sides share 12v?

I had the same problem and it was a crack in one of the pcb lines as it ran across the bottom. Sorry I didn't take any pictures. I just soldered a wire to join the track but not at the actual break, further away where it was easier to find exposed track to solder to.

IIRC each side of cluster had it's own ground connection for illumination. As Taavi said, check PCB for cracks and cold joints.

One day a led make a shortcircuit and my dashboard goes only the middle.

Check ALL lamps etc.

Have a good look over the PCB. Probably there is just a small crack on the track that can easily be soldered.

So half of the lights in my instrument cluster if off.

I have checked them all and changed the defective ones, but still about half are dead.

Are the light bulps on the same pcb line?

So maybe I can just add some wires instead if one of the pcb lines are dead?

Or could I move tacho, fuel gauge, temp gauge, rpm gauge over to my old instrumenter cluster? I currently have a RS2 instrument cluster.
