I have a Panasonic CT-34WX54 34" and I noticed I have a dark area in the middle of the left half of the screen. It is a circular area about 6 inches wide. I notice it mostly during sports or nature pictures where there is a solid background. It isn't noticable during normal shows but during sports like basketball and football you notice that part of the field or court is darker. Is this repairable and what might be causing it?
When I show other people the is issue, they see a dark verticle band from top to bottom. I mostly only notice the circular area.

There are mainly two reasons for this fault. The first one is with its screen voltage settings. If the screen voltage settings have gone down [it can be happen automatically in rare cases], the screen will look dark. The second one is with its video output section itself. Anyway, you have to seek an experienced service technicians' help in this matter, if you are not handy in electronics.
The line of color is due to a failure in the vertical circuit. The main suspects are the vertical Ic AN15525A and/or capacitor c308 220uf@35volts If you have the capacity to do so, you should check the other electrolytic capacitors in the vertical circuit which are USUALLY located near the vertical IC in most cases you can purchase the part at https://www.encompassparts.com/webwiz/wwiz.asp?wwizmstr=WEB.SEE&partnumber=5760279&smodel=CT32SL15N or mcm electronics
Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.
