I CAN'T SEE!

I have a Clip+ 4 gig and the back light and the screen acts funny now. They turn off and on all the time, and most of the time its off now. And id say 75% of the time the screen is off while the system is on.  Maybe I’ve over used it in the last six months? I use it every day. When the screen doesn’t work I can still use every button but I don’t know what I’m doing. is there anything i can do?

it sounds like the OLED is going bad I would contact sandisk support

Silly question but, did you try a reset (hold the power button down for 15-30 seconds) and did you try (if possible) reapplying the firmware? 

Note that you have a 1 year warranty on the Clip+ in the U.S. (2 in the EU), and none is 1 year old, yet (it issued last September–keep that date in mind, if you don’t have a receipt).
