E34 OBC/clock only working when headlights are on?

[roo 41]

Hey team

Quick question here, last night I noticed my clock/computer screen was very dim while driving at night. And then when I turned my headlights off the screen went out altogether. Any ideas? Is the ambient light from the buttons lighting up going up to the screen and that's why it's dim perhaps?

It's this style:

Cheers!

hmm screen should be on all the time except when car is off, with the backlight coming on when you turn on headlights.

I have a couple of computers here i can send if you want, just send me a PM
