<p>I'm no expert, but it sounds to me like a bulb problem. A burned out lamp will work for a couple minutes, then turn off, but since it is only the backlight, you can still faintly see the image. I've seen it a few times in monitors/TVs. Also, if you wanted, I have an external floppy drive you could borrow (Jenison).</p>
