part is still recording.? I don't know why but the video display goes off on the camera and all i record is audio. Can anyone tell me what's going on?

i have no idea.

Well I am assuming that the lens cap is off and that you are filming in sufficient light. The issue that you are describing also happens when the ROM sensor is burning out, this is the part of the camera that captures light to convert into video. Possible causes are allowing direct light to get into the camera. To fix, well you need a new sensor - take it to the repair man!
