You have a bad backlight or inverter. The purpose of the inverter is to turn on the backlight. I suspect it's a bad inverter because that is a common problem on most LCD displays and you mentioned it turns on briefly - the backlight lamp is likely good..

It's free and it won't put a watermark on the video...which is great 'cause all the other free ones out there will. Anyway i hope this helps.

My Sansa e260, came refurbished with no program for it. I just downloaded one, but now my computer will not show me the contents of my Sansa? Is there a better way to get a program for my Sansa? I'm just incapable of removing/adding music to it at the moment, and it's frustrating!
