Here is the message that has just been posted: *************** Just a reminder.. So after a couple of those, I got aggravated as it looks much worse in the email than your actual post. Either way, it is what it is and it's behind us now. I have to get some NiCads for the camera and money is SUPER tight. That is why from time to time I post things that I wish I could sell. I am glad that people want to see what I have, but frankly I thought that such a set would be a pretty common visual, and initially I wasn't probing for technical information that might require a shot of some exact part or whatnot. Either way, thanks for the interest and I will do this as soon as I can.

I saw the color roundies and the 1950s sets still in use during the Seventies as well. I thought they looked great back then even with all the Sixties and Seventies stuff that was around which I also liked. Once the all black plastic cabinets became the norm, all I wanted were vintage sets from then on.

OK folks, I'm going to try to upload a couple of shots. I found it necessary to take two to get the best portrayal of the set. I also thought that footage from the Woodstock festival in 1969 would be nice and colorful! I hope this works and I hope everyone likes the set. I think this is a great example of a completely unrestored survivor!

OK! That worked rather well. It's no tall tale that these Zeniths produced a super rich color picture! I thought that I would note that it's really interesting just how far VOMs have come. That is my Hickok VTVOACM (vacuum tube volt, ohm, ampere, capacitance meter) as I like to call it, sitting on top of the Zenith 5111. It is the biggest meter that I have ever run into! Behind the Zenith is a 1948 RCA 8T-243 sitting on top of the 24" space Command that I am always bitching about. This color set coming to life might just mean the end of the Space Command. I just have too much stuff for one modest abode!

Glorious Lollipop Color...Ain't NOTHIN' quite like it ! (grin) These new sets w/their AFCs, AFTs, PDQs, all that other garbage just CAN'T really hold a candle to a good ol' Roundie in good shape & tweaked up properly...

I think that the best thing to do is to keep the use light until I can afford to replace capacitors and/or other needed components so I don't fry a transformer or whatnot. Also, it's easier to restore a set that is already working then one riddled with problems like my 58 24" Space Command which now MUST find a home. |

That Zenith looks great. Now you've got me wanting to fix my Zenith roundie. It has been restored but something has gone reducing the vertical height and skewing the linearity.

Thanks! What model/year do you have? I NEVER would have thought that this set would be any type of attention getter; especially with the metal cabinet, which I have been told makes it MORE special. Have you checked any tubes yet? Since your set is restored, I tend to think of tubes going as opposed to caps, but one never knows for sure I guess. The tubes I replaced to get my set working were not absolutely bad on a tester, but more marginal or weak. Maybe color sets like fresher tubes! LOL!

That's a nice set and a good looking CRT! Even though the metal cabinet sets were considered more "low line or utility" they were usually the first to get thrown out, junked, scratched, beat up, etc. It just seems that they've become more rare as survivors nowadays.
I'd be curious as to all the different color schemes that would have been available. Back in the seventies, I had a black ctc-12 and a silver/bronze color ctc-20. I do recall seeing a black Zenith roundie in a bar setting once.... |

Well folks, I guess the nearly inevitable had to happen sometime. The Zenith lost color all together. There is still a decent black and white picture though. I checked all of the color related tubes and video stages. All I found was a shorted 3rd Video IF tube; replacement made no difference. I already realize that a recap is needed in most old sets, but right now I just don't have the time for the complete job. I am pretty new to the color TV repair scene so any pointers will be welcome and appreciated. For now, I need to do a good visual inspection and some VOM checks underneath. I have already noticed that what is called a "horizontal efficiency" coil's plastic structure seems to be broken internally, but for now I see no horizontal issues; just no color.

Congrats on getting her going!
I'd make note of the settting of the color killer control, and then try tweaking it, that is how I fixed the no color problem on my 71' Zenith. If the level of the color signal droped, but not below the min necessary level it could cause the collor killer circuit to turn off the color circuits because it is not recieving the proper signal level, which can be fixed by readjusting the color killer control. Also if the color killer control is dirty or open the same problems could result. It could be anything, but that is the first thing I'd check as it is usually the easiest thing to correct when bad. Keep up the good work! Tom C. |

Hi Tom! Yes, with little knowledge of color television circuits and the nature of their operation, I guess I can say that I am lucky that terms like chroma, R-Y/G-Y, and color killer sort of clue me in on key areas to look into. Last night I did try adjusting the color killer pot and could easily see that it definitely needs cleaning by its somewhat erratic reaction. However, no matter what adjustment I made I never saw an actual color picture. When I turned it up (or clockwise) I would get what I would call color bleeding into the black and white raster, so I turned it back down. I did notice that when I tune the fine tuning slightly off where a color signal would be present, there is what I would call a hum bar, or some type of interference present just left of center. This goes away if I tune away from where the color normally comes in. Perhaps a capacitor? I hope this makes sense! Like you said, "It could be anything." Thanks for the advice!
