Television and Home Theater

Hi there. I've got a Panasonic rear projection model PT-51G44CA chassis #AP815. The picture on it is great with the exception that it has recently begun to "zoom" in and out. If you are watching a program with a ticker across the bottom it will zoom in enough that it cuts this part of the screen off (as well as the corrisponding top and side). When it does this the picture also becomes very grainy. it is driving me nuts and any help would be appreciated.

I have a Mitsubishi VS-45607 rear projection tv.It currently has a problem with the screen having lines rolling vertically.Problem was intermittent,but is now constant.I've been having trouble finding any repair information for this tv,but I have found out this is a common problem.Any info or help that can point me in the right direction would be greatly appreciated.Thanks to all.

I turned on my Panasonic PT-53WX42 today and it did not display any images then turned off by itself after a few seconds with the power light blinking three times.

I waited a half an hour and tried turning it on again and now it's turning itself off after a few seconds and blinking once.

Anyone that has a Panny service manual know what this means? Time to call a repair technician? I've had it since 09-2002 with no problems until today.

Any help anyone can give is greatly appreciated.

Thanks!
