The screen has gone dark on my Fluke 434 3-phase power quality analyzer.  The backlight control won't make it any brighter.  I know it is not a fuse because I can hear the meter power up.  Any ideas what the problem  or how I might be able to fix it myself.

Not sure if you've solved this, but I changed all the little SMD electrolytics on my 434 and it solved the screen darkening issue. Hope this helps!
