You are facing this problem due to a burnt polarizer filter just past the blue filter for the blue chip.
This TV has a three chip design with red, blue and green chips.

Get new polarizer for your tv from panasonic .

I think the video cable for my xbox is messed up. Why does it keep showing up these little circle things? Whenever I turn on my xbox it doesn't come up anything but a black screen with little circles...


NOT HD: Make sure red goes to red, white on white, and yellow on yellow, also make sure the switch that is on the xbox wire plug says TV not HD.

HD TV: Make sure red on red, white on white, yellow on yellow, blue on blue, green on green, etc. Also make sure the switch that is on the xbox wire plug says HD not TC

Tv rainbow in screen


The picture tube has become magnetized, possibly by someone getting a magnet to close to it. You can de-magnetize it using a strong magnet (cow magnet or similar). Place the magnet as close the the screen as possible without touching it to the screen. Starting at the middle of the screen and slowly (not too slow, about one full circle per second should do) move the magnet in a circular motion. With each full circle move the magent twards the outside (making a larger circle) as well as moving it farther away from the screen. Using a magnet will not harm the screen, so play with it and you'll soon get the feel and will see what you need to do.
Tv's have a circuit built in to 'Degauss' (demagnetize) the screen each time you turn it on, but this will only work if the set is 'Cold'. If the set is left off for 2 hours (to cool doen) and does not demagnetize when you turn it on the circuit is faulty.

Image has big yellow


Hi Zenmast

This is a burnt LCD that will need replacement. If the circle is yellow on a white screen , then it is your blue LCD that will need replacement.

Light Blue Circle in Center of the Screen


Hello BruceD,

What you may have is a magnetism problem. I would suggest that you try deguassing the CRTs first before looking into replacing the CRTs. You can have a TV technician perform this for about $50.00 - $60.00.

Thank you,
