Recording Problem.

I have a Sony CCD-TRV128 Handycam. When I try to record something. I can hear the voices, but I can't see a picture (the lense cap was not on). I tried taking out the battery and setting it on the on position (about 10 minutes). I place the battery back in the unit and turn the camcorder on. The LC screen was black w/ a green line down the left side of the LC screen. Please help me! My grandson is playing his last football game (peewee) and I want to tape this game. I've tried Radio Shack, Best Buy, Targets and even Walmart, but no one could help me. Pleeeeeeeeaaaaaaasssssssssseeeeee HELP ME!!!!
