I have a TH-42PX25 Panasonic plasma TV. Had it for about 4-5 years.
Problem.
On cable TV and with my DVD, horizantally from left to right I get 2/3's of the picture and at the end of that on the right side of that a repeat of 1/3 of the same picture/frame. Using the TV on HDMI all is perfect!

Any thouights where to look?

Thanks for any suggestions.

Bill
