    I have a 27" RCA TV that a someone gave me to fix and it had
    discolored screen...taking a guess that it was the degaussing coil o
    it's circuit at fault; I found that the thermistor disc? was blackend
    I moved it to check if it had a bad solder joint but the darn thin
    crumbled, now I don't know what to replace it with...It WAS a silve
    disc no larger than a dime and had two pins...I have junked TV's
    could take a thermistor from. Does it have to to a perfect match
    Thanks, Johnso

    You should be able to use just about any two pin degaussing thermistor
    from another TV.

    Pending on the specific RCA Model and Chassis there may be a specific
    thermistor suggested, however Andy is absolutely correct in posting that
    almost any two legged degauss thermistor will suffice. <

    Call any major electronics parts supplier, or the RCA service rep directly.
    You can order a new thermo-resistor for your set. Just give them the model
    number, circuit board location number, and the part description.

    It would sure help if you would give us a model number!!!

    its called a PTC (positive Temperature Coefficient )or family of that
    device. which really means nothing more than
    it gaining resistance as it heats up via the
    current passing through it that is energizing the
    degaussing coil.
    you should be able to use one from a junker.
