Question

Help answer this question below.

I have a 25" Panasonic TV about 5 years old. Suddenly when I turned it on, I had concentric rings of color on the screen. It's gray-green in the middle, then a ring of red, then purple, then green, etc. out to the edges.

    I now have the same problem on a 32 " Panasonic...I hope this helps


    25.38) Color rings - bullseye pattern


    This probably means the degaussing circuitry is terminating suddenly instead
    of gradually as it should. The most likely cause is a bad solder connection
    to the degauss thermistor or posistor or something feeding it.

    You can confirm this by manually degaussing the screen with the TV or monitor
    turned on. If the problem disappears, the above diagnosis is probably valid.
    Check for bad solder connections in the vicinity of the degauss components
    and AC line input.
