No picture in LCD or viewfinder

While in camera mode on my Canon GL2 I am unable to see a picture on either the LCD or viewfinder screens, all that shows up is black, not even my data screen shows up. The camera is turning on, the battery is fully charged, I am able to use VCR mode, and I also recieve audio while in camera mode. I hit the record button while in camera mode to see if the camera was still able to record a picture, and it is able to record both picture and audio. The problem is specifically that while in camera mode on both my LCD and viewfinder all I get is a black picture. Beyond opening the camera up, which I have no idea how to do I feel that I have exhausted all possible solutions to this problem. Obviously I cannot use the camera if I cannot frame shots, yet video and audio will still record to a tape as I alluded to previously. If there are any possible solutions before I take my camcorder back to my dealer for inspection I would very much appreciate the tips. Thank you for your time!
