Vx Cluster - Single display - backlight no power?

Postby JohnDee68 » Mon Mar 07, 2022 1:44 pm

Hi guys,

I have a Vx cluster with the single display that has recently lost its back light to just the computer trip section of the cluster. I thought it was a globe failure, but on measurement after the replacement globe still didn't work, I found there is not significant voltage reading at the globe contacts on the PCB of the cluster.

I have checked the Grey and the Brown/white wire feeds and they seem to be ok and all other back lights of the cluster work fine.

Any thoughts or suggestions, maybe someone else had this issue and knows if it is a simple fix or is it maybe a whole cluster replacement requirement?

thanks.
