Replying to Problems with my Portable DVD!

Ok, so my portable DVD player turned off on me because of low battery. I tried a PSP charger in it and tested in for like 30 seconds and it worked.
So, I let it charge for a few hours, come back, and try it out. It works for like 10 minutes then the screen gets really white, but the picture (I was playing xbox through the DVD player) was still showing, but quite faded, in the background. I turn the DVD off, then back on, but it doesn't turn on. FUCK!
