    My Sony KV27TS32 the other day displayed a funny picture, turning it off
    and on restored the picture for about 2 mins. The sound is still working
    correctly. I took a picture to better explain this. Is the tube gone?

    A bit of history of this TV. I changed the 3 trans and resistor on the
    powersupply about 3 months ago.

    Thanks everyone for your help!

    Check the resistance of the degauss coil... maybe its open.

    When you first turn on the TV do you hear the degauss energize ?

    Sorry for the double post, I refreshed the page on accident.

    I don't know where to check the resistance of the degauss coil. I know
    nothing about TV sets, I thought i just give it a try with my little
    knowledge on electronics.

    I do hear it energize. It makes the same sounds as it did before it
    stopped working. Only now I get the funny red, green, blue swirls.

    Thanks again!

    tapping on the side of the set restored the picture. I opened it the set
    and lifting the side where the posistor is restores the pictures. If I
    lift up and hold the board the picture is perfect. Looks like a bad
    connection somewhere, resoldered all the joints but still a bad connection
    somewhere. :(
    any thoughts?
