Automotive electronics?

Hi all;

I just found this forum but I'm not sure if maybe this subject is not-for-here.

I have a Futaba VFD module on my vehicle which displays the climate control array.
I am trying to troubleshoot an issue with the display in that the unit switches all work, but the display does not light up.
A TSB from General Motors says the cuase is an "internal processor reset".

Can anyone point me in the right direction?

Thanks and take care.

Dave

check the power for the VFD, they normally require a split rail supply

+v 0v -v

if one side goes missing they stop working.
