Test LCD backlight before ordering a new one

[tobiasBora]

Hello!

As I reported recently, the backlight of my 60D suddenly stopped working, and I got an error 70 (that I can bypass). I'm more and more confident that the issue is a hardware issue, however after trying to open the LCD case+remove the plastic around the screen pivot axis, I can't see anything obvious (no disconnected/broken cable).

I was planning to buy a new LCD screen, but I heard that the problem may be a broken fuse on the mother board... for that reason, I'd like to know if there is a way to check the LCD backlight, for instance by plugging some wires to a +5V current.

Any idea how I could test my LCD backlight, and potentially discover the failing point?

Thanks!
