I have a Sony 65" Rear Projection unit. (don't remember the model #) and the picture keeps jumping. What I mean is, the picture seems to be pulsating in and out. It's very annoying. I'm also having a problem with keeping the TV in focus. I have tried manually adjusting the convergence twice and it helps for about a day but it get's out of adjustment again. Does anyone have any suggestions. By the way, the TV was built in 2003.
Thanks
