I used to take care of 300 + Zenith hospitality 19" TV's for a major Cincinnati hospital. It used a similar chassis 1984 - 86 vintage. We had lots of issues with the startup circuit board. That was the #2 issue we ran in to. The number #1 was the channel selector rocker switch. You had to go through all channels to get to the off position and the nurses instead of holding the switch down until the set turned off, they would stab the switch in rapid succession until the set went off. The switch would open up and not change channels or stick on and the set would rotate through all the channels over and over. #3 was lose windings on the flyback or a small inductor in the horizontal circuit. The TV would squeal and the younger patients or nurses would complain of the racket. Coat the inductor with Glyptal and send it back out.
Over the years, I've seen a few of those Zenith hospital sets that had either the 9-160 module, the 9-181 and 186 modules, and the later one with the 9-470 main module. Externally, they all looked alike and then they came out with those crappy "new horizons" and "HealthView" sets (can we say bad picture tubes and burned up power supplies?). The local hospital that we used had 19" Sylvania sets that dated from the mid '70's and they were replaced in about '87 with Magnavox 19" cable ready sets with electronic tuning. The old Sylvania sets had a motorized VHF tuner, with a cover over where the UHF knob would have gone, and the TV was set to turn off on the UHF position. I've had a couple of those over the years and they used a 3-board modular chassis with a power transformer and delta-gun CRT. The only commercial-grade Zenith that I own is a 19" Chromacolor II motel set, with built-in AM/FM radio from 1979. It uses an inline-gun tube and a modular chassis that folds down to gain access to the back of the chassis.
I can't believe your family tried to deprive you of the fun and satisfaction of digging through your junk pile to find a video transistor! I didn't work much on TV's, but I do remember that "Capitol Records Building" style flyback coil from a Zenith I got second hand back in the 80s. (I think mine stood vertically on the main board.) It had the digital tuner with 10 key, but no remote, no channel up / down, and no memory, so every time you turned it on, you started at Channel 2.
I’d like to thank you and Shango066 for doing your videos. Since the pickings on TV are slim, I’ve REALLY been watching both of your guys videos. I look forward to each new one !
A color tv was a luxury. We only had one from 1969-89. Any others were B&W. If the color went out, we watched B&W again until we got the color set repaired.
I watched b&w on an ancient set until I could finally afford a cheap import Teknika color tv with no remote in 1983. (The cable co. required a set top tuner anyway, so a tv remote was useless.). The Teknika had a lot of hours on it but still worked great when I donated it to the animal shelter's yard sale in 2002.
Like Decades, Antenna, ME-TV and H&I for sci-fi stuff. All great in their owns retro tv ways. Of course they are all offered in Chicagoland but some many only get one or two of those OTA ( over the air), depends how far out in the sticks you may be living.
Also I'm with you in the aggravation department when I get some piece of old test equipment out and it had to be fixed before use. It does make you want to buy new. I have on my oscilloscope and spectrum analyzer. I have both old Simpson 260 and fluke digital meters. Just fixed the Simpson a tiny piece of metal got into the meter movement. A tedious but simple repair. I just ordered zebra strips for the Fluke 87 as the segments on the LCD are failing again and I am tired of cleaning the old strips every year. I noticed they were going out again while fixing the Simpson! Strips are arriving tomorrow.
I know the feeling, easy to get buried in just making your tools work. Right now my more modern analog scope is dead, and my old all tube RCA that doesn't even do DC coupling needs recapped. I might have to fix one to fix the other, to fix whatever comes along that I want to check with a scope.
I always like the color picture on an old GE tv I bought new in 1989, it was a 19" with a mechanical tuner. You have one in your shop exactly like it. I also liked the color picture on a 19" Magnavox we bought new in 1994, it was a good tv. The GE was a cheap made tv, but it had a great picture.
I ended up giving that set to someone. The GE that I just retired, due to the flyback failing, had the same CTC136 chassis; but, had remote control digital tuning.
@@radiotvphononut Thank you, I think this is the first time you ever replied to any of my comments. I wish I had your knowledge of electronics, I loved playing around with electronics when I was a kid growing up and when I was lots younger than now. Back in the 70s, I was like a kid in a candy store going into a Radio Shack. I was a kid then lol. I wish I had the money and time to travel to Mississippi to meet you in person. It would be great to see your collection of electronics and shake your hand. Being that I am a poor working class stiff, that is not possible. When I see your videos of repairing a radio and dialing through the Am stations, I find it amazing that WDIA is still on the air in Memphis. I was born in Memphis and lived there until I was almost 16 years old. We moved to Texas in January of 1978. The only thing I can say about Memphis it is a good place to be from, FAR AWAY FROM ! lol
Great video.👍Cozi TV is the only channel I watch, the rest of these channels along with these new TV shows are friggin garbage. I sure miss the days of watching cartoons and the older shows after I would come home from school.
I’d take the HOT, flyback (and tripler, if it has one) out of that set you grabbed the transistor out of, and throw it in the set with the shorted IHVT; if it works, great, if not throw some fireworks in for a shango066-style EOL video and post it here on RUclips. My take on TV is: “who needs TV when I have RUclips”. 🤠 After all, it’s not going to get any worse, so might as well have some fun with it!
I only watch Cozi, ME TV, and Antenna TV. Only have OTA since I got rid of satellite...I am very rural and cable is not available, hell I would not get it anyway. Only reason I have internet is because my rural electric co-op ran fiber optic lines 4 months ago and hooked me up.
Nice TV. It was made 7 months before my birth. I saw this and thought the red gun was perhaps maxed out. But then the date would eliminate individual gun controls on the board.
Despite the dark area in the CRT it looks like a nice TV. The colors are very good on that set. It works, so why not use it? I myself still use CRT TVs mainly because they still work well. At some point I will have a flat screen, but until then the CRTs are good enough!
You are lucky. I can only get 4 PBS channels over the air with rabbit ears due to a small set of hills near my house. BTW, I had a 1986 version of this same Zenith TV( only difference in it was the number plate around the tuners was silver, rather than black). Found the set in a trash can behind a college dorm in the mid 90's and it worked perfectly until the CRT failed and I scrapped it in the mid 2000's.
Meanwhile in Mexico they still show a few cartoons left like Spongebob on over the air in the afternoons which I believe although they also show some TV shows that normally comes out on cable. Cheers
I know that Channel 5 in Mexico shows SpongeBob which is great for kids who don't have cable there. Here in the USA the only cartoon shown in the evening is The Flintstones on MeTV other than Qubo in areas that have an Ion station which does show animated programming.
We had a 13" version of this. It always had a great picture. It started turning off randomly after a while. You'd have to turn it off and back on again.
The repair turned out well. Those old Zenith's had good color. Btw, would love to hear you make a rant video on the current bullshit going on in our cities with this rioting.
Sadly when Zenith sold out to Goldstar, : "The quality went out before the name went on". Goldstar CRTs were total garbage. I got tired of finding the bad parts on the PC board, only to have the CRT arc and take the main board out again. I worked for a Zenith ASC for years, and afterwards for an independent. Finally the CRT's were failing so often, if the set was dead, had red retrace or green retrace we just told the customer buy a new set, just not Zenith, LG Zenith, Lucky Goldstar, or Goldstar. (All the same ball of bad worms).
I recall getting a Zenith 27" from '97, with no green. I quickly found a bad green driver transistor, installed a new one, and it had a nice picture. I sold it to a friend, who watched it for about a week and then the tube arced, taking out the green transistor again. Then, there were the older ones where the shorted tube would blow up the power supply. You could replace the power supply parts and it might play for a minute, an hour, a day, a week, or a month; but, the tube would short again and blow up the parts. In about '98, they wised up and started using CRT's from other sources (those held up much better); but, by then, the damage had been done. It got so when I saw a '90's Zenith with blown up parts, I condemned it on the spot. I remember installing an Opti-Chrome rebuilt A68ACT00X in a set and it was no better than the Zenith originals.
I have the same model from 1981 thats digital.. Looks like the same exact TV just with the digital tuner.. Mother got it back in 1997 from a customer she worked for.. I remember it got wet and would not turn on due to her having a pickup truck and it raining that day she got it.. I was still in high school at the time.. It still sits in my old entertainment center.. I stopped watching it around 2009 when everything went digital.. Still works as far as I know
I hardly watch TV anymore. I use my TV set as a computer monitor to watch mainly RUclips. I don't watch any other streaming services. The DSL costs enough as it is, but it's half the cost of cable Internet. I only get like 10 Mbps download, but it's enough for most servers even at 1080 video. That's with me sharing it with my sister.
I paid $205 tax and all for my first TV purchase and it was color. It was back in 1985 and I used it for watching and as a monitor for my Tandy MC-10 micro computer. I don't have the TV anymore and I've never purchased another set. I stopped paying for cable in 1989 because it was too high then. I get all of my entertainment on my 10.1 inch tablet now days.
Except for a few models in the late '70s with the multitude of little plug-in modules that always seemed to develop intermittents due to the weak tin plated connectors and the '90s sets with the picture tubes that seemed to have cathode poisoning issues since you had to rejuvenate them about every 2 months.
I have a 14 inch JVC I ART CRT Tv and I love it. It had been sitting outside for months. I brought it Inside and it worked. The CRT buzzes but that's it. I resoldered a resistor because it came off. I will keep it until it dies. Does anyone know how to stop the buzzing?
Games before the LCD era are designed to be played on CRTs The graphics don't look right on a new set. Also, if you can mod the old TV to take RGB (and most newer sets can be modded easily), you can hook just about anything up to them. Even pretty cheap sets will give outstanding results from RGB. 80 column text NO PROBLEM! Modern TV sets are in the wrong aspect ratio and when it comes to really old stuff, cannot be made to work at all without serious modifications to the game system. A lot of older game systems only work with RF and there is just no way to get an RF signal into a modern TV because there is no NTSC tuner.
@@tarstarkusz I've not played with the latest, but I've not yet encountered a LCD TV with a tuner that didn't tune NTSC, usually you just punch in channel 3.0, some even play static. It will have the usual problems, lag, 240p processing, looking bad on general, but it will work.
@@Broken_Yugo That's strange. The ones I have won't tune in NTSC. Why would there be any lag if it has an NTSC tuner? As I understand it, the lag comes from frame buffering and you are seeing and hearing the game some milliseconds behind the console. But if there is a built in NTSC tuner, why would it need to buffer anything? Is it not building the screen line per line or something?
@@tarstarkusz Exactly, the panel is nowhere near fast enough to draw it line by line, so the hardware in the TV builds a frame in a buffer from the interlaced NTSC signal (usually mangling it to some degree in the process) and then shows that. You're always at least a frame behind and 240p games rarely show right, any of the dimmed flickery stuff common to 8 bit systems will show up combed instead. Samsung were known for getting that right, but idk about current models.
Wide-screen 16:9 OTA signal through converter overscans the horizontal width of a CRT which is 4:3. I get that along with the 'postage stamp image' in the center of my 30" Zenith System 3 CRT TV. Annoying as heck and can't be over-compensated through the converter at all.
Seems like a suitable replacement. At least it wasn't made in one of their Mexican plants (lots of labor disputes, from what I remember); I worked on some of that crap in the 1980s and it looked like stuff kids would cobble together in a Montessori school. As I said on the previous video, you might want to check the capacitors in the horizontal output circuit of that GE; I don't remember the part number or anything like that, but a blue disc capacitor failed on my CTC-136 set and it behaved just like a shorted flyback, even though I got it running again for the cost of a new capacitor, a fuse and an output transistor.
My '87 Zenith, made in Mexico, just started acting up last week. I paid five bucks for a 21 year old tv and eleven years later the darn thing goes on the fritz. I bet it's going to cost a hundred buck to get it fixed.
It's sad how that kind of modular design was gotten rid of. I see how they wanted to keep business and make money by selling new sets rather than making new ones repairable. But I call bs on that - because more people on the Earth every year ensures that modular design wouldn't lose companies money.
Having to stock all those Modules and some were pretty expensive like the power supply. My parents had a 1976 Qusar tv one of first with plug in modules works in a drawer. Just pull it open from the front and then you access the insides.
Would you say that you have to have some type of electrical skill or knowledge to even attempt to try this for the first time? I’d like to get off into fixing these type of TVs.
My CRT TV started just staying on for about 10 secs with no sound then a soft pop, and it dies. Its only 19 yrs old and I'm quite disappointed. Still will not purchase a Wall of Mart Chinesium POS. Have a small Goldstar from 1996 I will use.
Have a Philips roku streaming tv Nice tv for the cheap price..only watch the free stuff. What I think is stupid is it turns on in the middle of the night then I turn it off and it turns back on again. This is a known problem and needs a firmware fix. This happens when the tv updates. Why can't it just update with out turning the whole tv on and waking me up inthe middle of the bloody night. ( someone said just unplug the tv at night, but that will kill it over time,) The old TVs were built a lot better
TVs have become so cheap it's hardly worth the trouble. You can get flat screens all day that will beat the hell out of any CRT for everything but vintage video gaming at Goodwill. The one in my living room I got out of a garbage pile, replaced some caps and it's good.
It cracks me up that you are doing CRT videos and Shango066 is doing TRF sets right now 🤣
Yeah, we must be swapping roles.

Another thing I remember about those '80's Zenith sets is lightning or a surge hitting them and knocking out the transistors in the start-up circuit.
That set has a nice picture. I really like the way CRTs look.
Just bought my first CRT TV. I like the appearance of it over my LCD monitor

Back in the mid-80's, I remember seeing those TV's advertised in newspaper ads on sale at Appliance-TV City for $240.00, which was a pretty hefty sum.
Ahh Adam-12. Guess that is what LA was like before Shango was born.
As someone used to live in the San Gabriel Valley in the 1960's, It brings back memories.
II knew you would like Cozi TV, you’re right, it is the only channel from the antenna that’s worth watching.
Like Decades, Antenna, ME-TV and H&I for sci-fi stuff. All great in their owns retro tv ways.
Of course they are all offered in Chicagoland but some many only get one or two of those OTA ( over the air),
depends how far out in the sticks you may be living.
I like grit tv for westerns.... although i don't care for their censorship.
BUZZR is a great channel for vintage game shows like Match Game
Radiotv, I was salivating for a couple of new tv videos from ya....thanks for doing this.......enjoyed it very much.
Also I'm with you in the aggravation department when I get some piece of old test equipment out and it had to be fixed before use. It does make you want to buy new. I have on my oscilloscope and spectrum analyzer. I have both old Simpson 260 and fluke digital meters. Just fixed the Simpson a tiny piece of metal got into the meter movement. A tedious but simple repair. I just ordered zebra strips for the Fluke 87 as the segments on the LCD are failing again and I am tired of cleaning the old strips every year. I noticed they were going out again while fixing the Simpson! Strips are arriving tomorrow.
I know the feeling, easy to get buried in just making your tools work. Right now my more modern analog scope is dead, and my old all tube RCA that doesn't even do DC coupling needs recapped. I might have to fix one to fix the other, to fix whatever comes along that I want to check with a scope.
I'm glad it was an easy fix.

The big reason why people are starting to get TV's from the 1980's 1990's and early 2000's is retro video games.
Hit the nail right on the head. Even RCA's little 13" sets from the early to mid 2000's are quite nice - as they have composite inputs.

As I said on the previous video, you might want to check the capacitors in the horizontal output circuit of that GE; I don't remember the part number or anything like that, but a blue disc capacitor failed on my CTC-136 set and it behaved just like a shorted flyback, even though I got it running again for the cost of a new capacitor, a fuse and an output transistor.
What's funny is this '84 Zenith is made in the USA; but, I have a 19" Zenith Chromacolor II from '78 and it's made in Mexico.
My '87 Zenith, made in Mexico, just started acting up last week. I paid five bucks for a 21 year old tv and eleven years later the darn thing goes on the fritz. I bet it's going to cost a hundred buck to get it fixed.
10:03 the black ladys blazer has color bleeding or is it just CONVERGENCE
It's sad how that kind of modular design was gotten rid of. I see how they wanted to keep business and make money by selling new sets rather than making new ones repairable. But I call bs on that - because more people on the Earth every year ensures that modular design wouldn't lose companies money.
Having to stock all those Modules and some were pretty expensive like the power supply. My parents had a 1976 Qusar tv one of first with plug in modules works in a drawer. Just pull it open from the front and then you access the insides.
Would you say that you have to have some type of electrical skill or knowledge to even attempt to try this for the first time? I’d like to get off into fixing these type of TVs.
Did you and Shango trade places? Since he is repairing recordplayers and you tv's 😁🤘
I want that tv
I need to get rid of my 90s and 00s junk TV and get some from the 70s and 80s with the fake wood.
My CRT TV started just staying on for about 10 secs with no sound then a soft pop, and it dies. Its only 19 yrs old and I'm quite disappointed. Still will not purchase a Wall of Mart Chinesium POS. Have a small Goldstar from 1996 I will use.
How long did they make that model? Thought it'd be older. My aunt used it until like 2005.
The newest 19" Zenith knob-tuned TV that I've seen was from 1988; but, I feel like they were made until 1990-'91.
Have a Philips roku streaming tv
Nice tv for the cheap price..only watch the free stuff. What I think is stupid is it turns on in the middle of the night then I turn it off and it turns back on again. This is a known problem and needs a firmware fix.
This happens when the tv updates.
Why can't it just update with out turning the whole tv on and waking me up inthe middle of the bloody night. ( someone said just unplug the tv at night, but that will kill it over time,) The old TVs were built a lot better
TVs have become so cheap it's hardly worth the trouble. You can get flat screens all day that will beat the hell out of any CRT for everything but vintage video gaming at Goodwill. The one in my living room I got out of a garbage pile, replaced some caps and it's good.
The older LCD TVs are better made but holy bezels, Batman! The plastic in the front bezel takes up more than the teeny little LCD in the middle.
I'll put stuff up, dig it out later and it not work like it did.
BTW ive known smokers that have lived years longer than non smokers.
I want this TV I am give money
