I'm hoping to get some ideas of what may be the issue with my TV. It is a direct view Panasonic flat screen. It is from the Tau family, but I don't currently have the model number.
Current Problem: Once powered on, the image is not displayed across the whole screen area. It is almost like a computer monitor that has not been adjusted to use the whole screen. Probably between 1-2" on all sides. The amount that it is "shrunk" varies depending on the brightness/color of the image. When the image is dark the it is only about 1/2 inch around the outside, but when the image is bright, it will increase to 2+". Also, on scenes with lots of color (particularly yellow or white) the screen will take on a distinct hourglass shape. Once again, this varies depending on what is on the display.
I have tried the geometric corrections on the set and it does not have ANY impact on the image.
It seems as though this is related to the power supply and the amount of power required to produce the image, but I am just guessing.
Previously this set had problems that it would simply power itself off and not power back on. After 4-5 trips to the shop that problem seems to be fixed but I'm guessing this could be related.
Any ideas are appreciated.
Thanks,
Mark
