RCA TV - Whites have yellow tint after spontaneous power cycle
I have an 32" RCA TV (F3267SB CTC187CL3) . It's one of the ones that
had the tuner problem but that's not the issue now. Last night while watching it seemed to turn itself off, then back on instantly. There may have been an audible pop but it happened so fast that I can't be sure it was really a pop or just the volume cutting out and back on. The picture returned immediately, with the only sure sign it went off at all was that the on screen channel display came on. Since then whites have had yellow, maybe slightly green, tint to them. Some whites seem more affected than others. While watching hockey the ice seemed pretty white but the players with black jerseys had a hazy trail of yellow tinted ice following them. It's at least 10 years old and it's probably time to spring for a fancy new HD LCD set but it's Xmas time and funds are a bit tight. Any thoughts on what the problem might be and whether it's worth repairing? Thanks in advance. |

I don't have a degaussing coil unfortunately. The on/off cycles you are referring to, how long or short should the on and offs be? |

It takes about a half hour for the degaussing thermistor to cool off and trigger again. I doubt this is your problem but it's worth trying. |

It's been on and off quiet a few times since it happened, including over night twice. It's really not super bad, but annoying enough to bother me. |

RCA TV - Whites have yellow tint after spontaneous power cycle
The yellow smearing is indicative of either problems in the video drive-bias
circuits or the crt is finally giving up. "Meat Plow" wrote in message ... On Sat, 15 Dec 2007 08:34:01 +0000, James Sweet wrote: "stoneattic" wrote in message ...

He can hit the thermistor with some freeze mist I don't think the problem is Gauss as the shutdown may have been a result of some malfunction maybe even inside the CRT. |

RCA TV - Whites have yellow tint after spontaneous power cycle
Thanks everyone. I was pretty sure it was more than something simple,
or at least simple enough for me to fix, but figured I'd get some input before springing for a new TV. The TV is over 10 years old. We just picked up a Samsung 46" LCD.

Well I should be around to help you when your new set poops out in a year or so just kidding One last question, is this set worth taking it somewhere to have it looked at, or should I just put it out for the trash? |

If it were mine I would recycle it. Having spent time working on them for a living I surely wouldn't pay to have it looked at nor would I bother tossing it on my bench here at home. I recently had the same thing happen to my bedroom 20" RCA Tru Flat TV/DVD combo TV. Well not the same problem as you but the tuner failed. I gave it to my 15 yr old son for his room since all he ever did with his 19" TV was watch DVD movies. I took his 19" TV and gave it to Goodwill. I bought myself an early Christmas present, a 32" widescreen HDTV for my bedroom I took your advise and put it out for the trash. This guys tuner had failed ages ago but I got around it by setting the channel to 00 and using s-video and RCA inputs. With the messed up tuner and yellow issue and the fact it was 10+ years old it was time to retire it. I just hate throwing anything out that MIGHT be useful. Thanks for all the advice everyone. |
