Man I love your setup - vintage roundie, records and stereo speakers everywhere. I do, on a purely freelance basis, what you demonstrated in this video, albeit with patterns on DVD and BluRay. Today it's called display 'calibration', but I think a better term would be alignment, as it is akin to wheel alignment - for your TV! 😉
I'm hoping you are aware that these old tube CRT's can and do generate extremely high voltages at the plates and caps, high enough to be deadly. Learning is great and yes, everyone has to start somewhere, but those old TV Repairmen went through highly structured training programs under mentorship of senior technicians, mainly manufacturer specific models. None of them (that survived) just sat down and trained themselves. Please be very careful. Assume the line is hot. Assume the plates are live. Assume the caps are charged. ALWAYS!
I have a degree in electrical engineering and mechatronics. I am very familiar with safety processes. I’ve been repairing vintage tech since I was about 12 and have had many people help me learn. I will be careful.
It would be wise to replace all paper capacitors in the set. Seems that the electrolytics are fine, but at that age, those are risky, too. You likely won't have a proper stable picture until the paper caps are replaced, and you risk damage since leaky capacitors throw off grid bias.
I’ve been collecting vintage TVs for over 30 years now and have yet to have an electrolytic explode. Heck some of these tube color sets were still in use well into the 80s and 90s. The more use these sets had the better the electrolytics held up over time vs a set that hasn’t been turned on since say the 1950s.
I remember old TV's took about a MINUTE to even think about coming on!

@@timtheenchanter0476 Thanks!
This tv looks to be at least 60 years old. Must have been a pain in the butt to get it working, and im glad you figured it out.

@@timtheenchanter0476How can we determine the truth behind this without the essential in depth duel of polyvariable?

Thanks!

I would love to but I am having a hard time finding any good guidance on how to do so. If you know of any good sources please let me know.
I believe at this point Zenith was using those orange Spraigh orange caps. This TV looks to be 1966.
@@edp9821 Were they film by then? I've seen maroon Spragues that were film, which, of course, is good quality.

@@td3993 orange gum drops they were called.
¿Cómo se llama el aparato donde colocas las cartas de ajuste?
Fantastico!!!
I hope this TV has been recapped. An exploding electrolytic is not fun.
It has, I refurbish vintage tech mostly TVs

Can you fix my zenith tv? it got lines on top and there's a dead spot forming on top
increible, but true.
That's very cool man. I didn't know that was a thing. What was that for?
