I have a Panasonic CT-26WX15 set, and sometimes there
is a circular area of the screen with a heavy blue tint.
It does not seem to show up on all channels, and is
not there when playing DVDs.

Re: intermittent blue circle on display
Yes this is certaintly a strange one, as you say not all channels have it?? Ok lets try to narrow it down a bit. Do you have cable or satallite ? Is the cable or sat. connectected through the video inputs or does your TV have to be on a certain channel? ok and you say its not there when your watching a dvd? The only answer here is that you have a problem with your cable or the sat system, as the channel stays the same on whatever channel your watching while on the cable, so if you have a problem with some and not others , Your TV dosent know the differance from one channel or another, as its always on the same channel on the tv . So what does this tell you?? Theres a problem with the sat or cable reciver! Cant be the TV as I said the TV doent know the differance from one channel to another as it always stays on the same channel. Sounds like you need toi have cable come in to check the impedence and signal streinth.. now if your sying thast the tvs on locals and some do it and others dont ?? then theres outside interference causeing this problem? Good luck

Make sure you have a HD cable / Sat box. Then make sure your using a HDMI cable connected from the TV to the box. Then you should be using the source or input button on your remote to verify your on the HDMI source or input option. Then make sure your watching a HD channel. It will say HD after the channel name on your interactive guide. Hope this helps.
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 [email protected] 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
