CE6000 - Blank Screen

[animenick65]

We have a CE6000 that's a few years old. It was cutting fine today, but then all of the sudden the screen went blank. The LCD does power on (gets darker) but doesn't display anything. None of the fans come on.

Any thoughts?

It's probably a main board issue. I would take the covers off and disconnect all of the cables from the boards. Air dust everything as well as you can, check the cables for damage or corrosion and plug them back in. If it still gives you issues, you can test the power supply for if it is outputting the proper power requirements and then move on to the main board replacement.
