Hi to all. I have a WS-55807 and a few months ago it started to have a "double vision" type of effect on the screen at times. It may go a week or days without having a problem and it may do it every hour. If a person is on the screen then you see another outline going around the person. Or if there is words on the screen then you see another set of the same words like your having double vision or something. When this happens I can go over and bump the right front top corner and it will go back to normal everytime. Then it may not happen for a week or 5 minutes. Any idea on the problem??? Thanks in advance for any help.
