    New (less than 2 months) 27" Daewoo. Turned off the other night then
    turned back on about 5 minutes later. Picture color was weird. Three
    circular areas inner was green then red (I think) then another color.
    Turned on and off several times and it would not inprove. Other TV's
    OK. All on cable. Next morning, and since then, its fine. Anybody
    know what may have caused this and should I be worried?

    Yes dont buy anything with Daewoo on it
    it is made as cheap and with as poor of quality parts as they can get .
    go buy Panasonic , JVC , Toshiba and you will have better luck

    They are really not bad compared to some other sets on the market.
    It sounds like the set got magnetized somehow. Either something with a lot of
    magnetivity was placed close to the set, or the set has a problem with the
    Don't worry unless the problem comes back.

    Not a problem, just ulgy. Take the set to shop and tell them to
    repair degaussing circuit & replace at least four capacitors to
    prevent future more damage. Should not be more than 100 to do both.

    Daewoo in 27" range has RCA CRT usually which is good.


  5. The mask in the CRT became magnetized. After switching off about 30
    minutes or more, the degaussing coil should be able to be re-activated
    again. A number of power cycles with about a 30 minute rest between
    them should eventualy clear this. If not there is either a defect with
    the degausser, CRT, or the CRT is very badly magnetized, and requires
    to be manualy demagnetized.

    Thank you very much.
    Now I know what happened and why the problem went away.

    Well the set cost a whole $149.95 on a super sale at a local supermarket
    the day after hanksgiving.
    It weighs a ton and is big so I will hope Jerry Greenberg is right and
    the problem will stay away. I suspect the rapid off/on at the time of
    the incident triggered the problem.

    Thanks to all that weighed in. Very impressive group.

    The picture tube is one of very few things that RCA ever makes that's decent.
