Zenith Inteq Model IQB50M90W
Last night we were watching a movie and the color on our tv, a Zenith
Inteq Model IQB50M90W, went extremely dark with very strong red tones. I tried the normal adjustments with no luck. I called the Zenith service number and the guy said to unplug the set for 35 mins to get back to the factory presets. If that doesn't work (unplugged now) he said that a tube package would run approx. $130 plus labor which I would definitely have to hire as even though I'm a do-it-yourselfer, I'm not very electronic minded. I told him the set was only 4 years old and he said that was rather premature for the tubes to go out in this unit, but wellll.....he did consider it worth fixing. I see a lot of people complaining of multiple repairs of these sets and I was wondering IS it worth fixing or am I just entering into a series of repairs when I would be better off getting a new set and cutting my losses? |

Thanks for all the possibilities. We tried unplugging the set to
return it to factory presets with no luck. Being as I'm not comfortable with electronics, I call the repair guy. He tried to adjust the color from the remote (I'd already tried) with no luck. He then opened the set and did something to adjust it from the inside and this did the trick. The screen he was using looked just like the one I use from the remote, but this method worked and he was able to get the picture adjusted. Why would it work from the inside of the set and not from the remote? He also said that he noted that we had an Hitachi "board" in the set, not a Zenith. Does this mean we might get lucky and not have the usual Zenith Tube problems noted by other posters? |
