@@waltergabriel3694 you don’t say, did you watch the video? He actually ordered from them in it as well. You seem like an astroturfer with this comment 😢
I stopped the tape. I need to confess that my man crush made me hopeful and giddy that SHANGO was reaching out to me. The chromacolor logo was convincing. I rehearsed polite ways to avoid political topics and bro mance the Zenith era. Then truth hit me, like a pina colada hangover. Thank you for clarifying. I'm grateful to be here with a CRT, even while my heart is mending.
It is amazing how one little wire can have such an effect on these old sets. Congrats on finding it and making it work once more! I do envy your knowledge, and thanks for sharing, I never fail to learn more about electronics with every video of yours that I view. I have always said, "to stay young, one must continue to learn!" Your channel keeps me young and at 72, I can use all the youth I can recover!
I worked on a handful of these in vocational Radio & TV in my junior and senior year in High school in the early 70's. That was back when you could still learn the beginnings of a real trade you could use in life. This brought back a lot of memories.👍
That's why it's daunting to get into electronic repair now. There's no type of class I can take anywhere near me to teach even the basics. The best we have is the internet and word of mouth.
Really enjoyed this video. Great find on that broken wire. And I agree that comparing notes with other people is smart and can save an ass load of time. Keep making them and I’ll keep watching them.
I wonder if 50 years from now, will someone like Shango be resurrecting a flat screen.... LOL Not likely I suppose. But this Zenith is a watchable piece of history and design 50 years later. Truly amazing yes! Cheers! 🍻 Great Video and Television! -Al
i resurrected a 55in plasma tv that im still using it was left for dead in the junk pile in town, i picked it up and sure enough no signs of life turns out one of the transistors on the power supply was broken in half, put a new one in and bang it worked easy fix
@@stevencarlson5422 The power supplies seem to be the Achilles' Heel of 90% of flat screen monitors, which is not too surprising. They're often an easy fix, but most people either don't have the knowledge, or don't want to bother. LED bulbs - same thing - the power supply in the bulb base usually gives out long before any of the individual LEDs burn out (except the bulbs usually aren't worth repairing; just cannibalize them for parts). I've made floodlights from the white aluminum-core LED PCB assemblies from dead LED bulbs, sort of like Shango's big handheld mine-exploring light, using an alternate power supply (around 60-62 VDC) and current regulator.
I would have sooooo loved to have had one of those in 1969. But now, surrounded by flat screen monitors doing the same thing. Some picked up at Goodwill for $4.99.
What a great little set. The picture appears to be about 70% there. Just needs that last 30% with replacement components. The sound from this set is surprisingly rich.
I recognize that model, my folks had the same one when I was little. When we got our Commodore 64 computer in 1983, we were using that old timer as the monitor.
I enjoy working on the Zenith Transoceanic transistor radios and they use the solder pot construction as well. Along with them being easy to solder and desolder they make a good test point when the components are in a tough place to access like the RF stage. I would avoid playing, 'The View' on the set. The components in the set will likely rebel left and right popping, exploding, committing hari kari. Taking a page from the SMT repair guys I use some good liquid flux for working on old solder joints. A drop or two gets the old solder flowing nicely. A small bottle with a good dispenser tip lasts for years. I also add new solder. Low melt solder can be very helpful if trying to heat two solder joints at once, or larger solder joint where a lot of heat needs to be dissipated.
Just amazing a wire with a diameter smaller than a hair could bring down a TV’s performance that much. When I think of what goes into diagnosing, targeting, finding and repairing a fault that you need a microscope to find…my skills and knowledge will NEVER advance to that level. That’s an Easter season worthy resurrection!
Love your channel and all your comments during the filming 😀 I wanted to let you know I worked on one of those Zenith 19" "Portable" sets years ago. One of the things I found was the transistor sockets in the video/if circuits were oxidized and making bad connection, which caused weak or no video and extremely low contrast. Just a suggestion for something to check. Love your videos and keep up the good work!
Good going there Mr Shango. A small word of caution: The voltage rating of these modern electrolytic caps tightly seam stitched, they have no reserve which older caps did have. It may be advisable to measure the peak volts before the tubes warm up and raise the voltage rating accordingly (say to 385 / 400v ) just to be on the safe side. Cheers from Germany
Another Excellent Video. Thank You for that. Cant believe you found & repaired that broken coil. I do remember cutting and breaking those coils to get them out of those solder pots. BUT the new ones were still available at that time. Great Job Buddy !
Nice fix, well done spotting that coil wire break. I thought the solder pots were known as turret tags, but that might just have been what the guy who told me about them called 'em. Great video as always.
I was given an early 25" Zenith console TV that had been thru a flood. I was planning to use it for parts, but I decided to try turning it on and it came up with a raster. So I took it out in the yard and flushed out all the mud. You could see where it had floated up and onto its side. After drying it thoroughly I got it working really well. I was even able to refinish the wooden cabinet. I remember those "solder pot" terminal strips. As I recall, there were 27 steps to set the convergence.
I have two zeniths from 1970 one 15"portable plastic, and one table top 19" space command 100 with a metal cabinet, both of which have minor problems like this, the 19 in has a fantastic picture even though the red and the green are slightly weak, the 15 " has other issues between contrast and brightness but still very watchable.
Nichicon capacitors are always my go to when ordering off digikey. Not the cheapest, but reasonably priced. and knowing they’re gonna last a lot longer than the cheap Chinese no name crap, I think it’s worth the extra $0.15 per capacitor
I've been watching your videos one after the other lately, so interesting seeing the investigation you go through to get these back in working order. I've also bought 3 retro black and white Philips sets and I'm planning to try to fix them as well. One is already working, two more to go!Thanks for all the informative videos! Ps: wow tv in Amerika is even worse than in Europe.. Already can't stand all the crap they spew here, but this is on another level. Good that you're having a laugh about it with your comments 😆
I can see the appeal in you fixing these old works of art. I mean, I'd even love to see a film (and I say film) about how some of these sets were hand soldered together, because I can't even fathom a time were all those components were hand soldered together to produce thousands of these sets. I'm from that time too, but... the set itself is so deceptive, it looks semi modern on the outside, like it was from the mid 80s or something, but then when you show us the undercarriage it's like something right out of the 50s with all the intricate components literally overlapping each other in the most intricate soldering network of components.
That process might have been filmed, like even possibly for training purposes, but would have been considered very proprietary. Buried deep in corporate archives somewhere. Does anybody now even have a clue as to who now owns such Zenith archives?
@@KameraShy I don't know about Zenith, but Tektronix' old archives of internal training films are on RU-vid. Look for the "VintageTEK Museum" channel. There's at least one film there - a 1969 film on the process of designing and assembling printed circuit boards - which shows some of the assembly processes. It shows the old black-tape-on-Mylar method of PCB layout, which is now long obsolete. I did a few layouts with that method in the early 1980s, before computer board layout software became commonplace. It was a very time-consuming process.
Hi Dan, thanks for the great videos mate, they are appreciated and enjoyed. I never cared for high-voltage too much so I stuck to solid state, but i always enjoyed the old reel to reel and other thermionic gear my parents left at my grandparents when they left I like the smell of the old warm hollow state gear, I have an old Yaesu FT101ZD which I, er, enjoy the smell of too, after a good chat on the thing, yes it's a fetish and No, I'm not proud of myself. Cheers Shango, making learning fun 👍
The beautifying paste commercial lists several products, they are all probably the same stuff in each bottle, with a different label. They remind me of E6000, Shoe Goo, Amazing Goop, the same stuff in each tube, they just label it differently.
Listen to the sound, that portable tv has sound and a bigger sound than any 65 inch flat tv today. That is great sound, what size of speaker does that TV have? You are right, the greens look good. I look to have good greens and good blues. Favorite colors.
Capacitor reforming is an actual thing that capacitor companies document, it's normal for any electrolytic capacitor to have to be reformed after being sat unused. The problem with the old ones is that they have had their seal break, let the electrolyte dry out and then let in moisture, ruining the capacitor even if it does reform at first.
Gee, when you were talking about the greens, I thought "Shango doesn't need any Blue Pills!" Ha ha just joking, great video. I remember how good these sets looked when new. Best picture in the business.
shango066 I am amazed at the greens on that tv it really is a sight to see bet its way better in person, also what was the odds of that coil wire being broken like that good thing phone cameras have gotten that good to zoom in like that sure helps see small stuff, i look forward to when you get more caps in and get it converged looks like a nice little set to use
I like these tabletop vintage TVs also yes Shango telegram tryed sending me a message telling me you had a gift to send me thought that was kind of odd
Loved the barber poling color effect. I wonder how it would look with a pair of 3D glasses? Also the herringbone pattern is cool as if it's being hit with microwave energy. Getting there Cool. Recap and adjust tank circuits?
One thing I just noticed about this TV is that it has both a coarse and fine UHF tuning knob, while my parent's 1970 B&W model had a see-through fine tuning drum that completely covered up the dial, so you had to twiddle the drum 10 times to get from station to station. Since both designs required exactly the same number of parts, I assume that was just Zenith's way of reminding the owners of their economy models that they missed out on something. Of course, it was easy to get around this annoyance by replacing the see-through-drum with a radio knob, then the dial served as the coarse tuning control and the little knob did the fine tuning.
It's hilarious that these scammers pick THE one guy that all his followers know, absolutely, that he would never have anything like this. Now, if it were promoting a new crepe erasing technology (you see what I did there?), then...
I get so many telemarketers it’s insane. Yesterday tipped the scales at 7 calls. My record of calls is 40 in one day and 5 within one minute. The person who used to have my number (who I know the name now thanks to the telemarketers telling me) put my number in a lot of stuff it seems.
most definitely. i took some classes where color bands were important to be able to read. i don't watch Mr. Carlson's lab. but "mmm, Crepe Erase! man" always talks about radiotvphono nut- nothing at at all like the inspirational resurrection channel out of torrence. also, HSN moments are fun
@@stirlingschmidt6325 My favorite scammers on YT are the ones who have a mess of fake accounts and they try to carry on a fake conversation concerning a crypto broker... Sometimes, you get lucky enough to be there at the right time as theyre constructing the conversation. And you get a chance to jump into the middle of it and say the MOST OUTLANDISH STUFF...🤣
