LCD flipout screen blank but works at certain angle?

I have a Samsung SMXF438N camcorder. The side LCD screen stopped working yesterday. At a certain angle it shows a display, but it's as though I've set the display to "comic book" mode. The Menu button doesn't respond, neither does the joystick button underneath it. I connected it to PC and the videos downloaded, and were "normal". But I can't delete them or play them back on the camcorder.
