If you have no audio or video and the TV is making a chirping or clicking sound the most likely cause is the convergence chips have shorted. You can get the parts and instructions on how to do the repair from www.TvRepairKits.com

Can you post a picture of what the video is doing? It shounds like a pincushion problem, but it may be convergence amp as well. A picture could clarify it for me so I would know which direction to assist you in.
