I was a design engineer at Zenith during the time this set was made (1973-1994). This set does not need the 4 lead cap replacement as this was from the model years before this set was made. The orange Sprauge caps fixed the issue. The bad caps were white from American Radionics. That problem put American Radionics out of business. This set was made in the Springfield, Mo. Plant.
And the dirty secret is Maggy used them too on the T991 IIRC chassis. Had 2 of them cut the neck. Spent 40 yrs at a Zenith shop, sure miss them. LFOD !
@@tomj4506 You are correct. Magnavox used the part as well. Zenith made the mistake of mounting the part on the heat sink of the horizontal output. This hastened the failure.
I had curiosity about the white ceramic plates with row of pins, in the CRT board have one marked as "HOT", exactly what is this? These looks as thick film resistor networks...
@@luizmarxsenjr They're probably hybrid ICs. At least the smaller one. The bigger might be a thick film resistor array, containing the output resistors of the video outputs (they might use thick film technology to make them low inductance).
Can you imagine that the TVs in 1977 he gets it tuned in what's on the right away CNN and you're talking about Joe Biden wow they truly are desperate for viewers
I received this very same tv as a kid for my bedroom. I believe it was a birthday gift. It was a very heavy and well made tv (stood up to alot of kid abuse and never looked any worse for wear). Even the knobs felt solid with alot of positive feel. I am very sure it was purchase at Sears (my Dad bought everything at Sears in those days) and it would have been around ‘77/‘78. It survived, in daily service, until around 1997. One day the picture and audio went dead. By that time, it wasn’t worth spending a dime on and was replaced with a new (nearly the last of the CRT) tv that lasted maybe one quarter the life of the Zenith. I don’t recall the Zenith ever going in for repairs.
I remember where I lived back then. (Western Pennsylvania) We could barely get One UHF Channel. But some days it would come in good. It used to have some good shows and Movies that weren't on the Networks, Iit was Channel 53. The regular Channels were 2. CBS 4 ABC. 11. NBC and there was the PBS Channel 13,. (Pittsburgh) WQED. for good old Mr. Rogers and Sesame Street!! Sometimes We could pick up Channel 6 from Johnstown,. Rsrely. We had the Big Roof Antenna.
Zenith seemed to have labor problems everywhere; the unions probably followed them from place to place.. I had to replace the power supplies in a bunch of Mexican-made 1980s monitors because they were smoking up the air in a hospital and once you opened the neat matal case, it was like a giant bird's nest with a slab of fiberglass embedded in it. Not the work of a happy shop .
Good old CC2! I remember unpacking these brand new in '77 and '78! I turned 17 years old in June of 1977, and I started working at the TV repair shop (Active Television and Appliance, Sylvan Lake, MI) in August of '77. I worked there until early 1981, so I saw the last generation of the Chromacolor 2's, and the very first System 3 sets! And in the case of RCA, the XL-100 sets, and the beginning of RCA's next generation after the XL-100, and I can't remember what it was called right now, senior moment!😁 It amazed me way back then, and now, how HEAVY these little Zenith CC2 13" sets are! I have one, was working fine and quit, I have to get around to repairing it one day! Thanks, for the great videos!
Love these TVs I can remember right out of high school working in a TV shop these were all over the place rca xl100 zenith chromacolor board sets nice to hear your voice again shango
Solid state TV chassis scared the crap out of me. The XL100s especially. Much more so than Sony. I was never a pro at any of it but got my feet pretty wet considering.
I have a 19" Chromacolor II, made in 1976. Yes the capacitor was replaced with an orange one. On mine I have noticed that when there is just snow on the screen, the image is rather dim. However it brightens up when there is a signal. Not sure if that was a feature since pulling and reseating the module boards seemed to help with that. Funny, mine starts off with a red picture before the green and blue warm up. Yours starts off blue before the green and red warm up. I think the Chromacolor II was the Zenith of Zenith. What I mean by that is it's a mix of technology new enough to run for decades before requiring service, with enough quality to ensure these sets still work after ~40 years. The system 3's, not as good of a CRT... then of course 1993 came along and Zenith CRT's went to utter crap. I keep my CCII around in part because I think it was the last of the well made Zenith sets. As in, still working 40+ years later with only some basic cleaning done for maintenance.
I had the 1978 model of this exact set for 20 years. Ran it for 1000s of hours for TV, Atari 2600 and my Colecovision. Still worked like new the day I sold it.
These were my favorite sets to work on. Pull all modules, spray clean contacts. Crimp VERY slightly each connector on the modules. Re- install. Then rap on the metal frame with something to be sure nothing changes :-). AND Yes, orange drop good, if white 4 wire cap we always changed that out.
It wasn't just Zenith that had the HV cap problem. Magnavox, some RCA's, and Admiral had the same problem. It did seem Zenith got the most attention however. The reason the 13 inch set was so heavy is because it basically had a full 25 inch chassis inside. A few mods for the picture size, but basically a full console in that little set.
i agree.... zenith was an archrival with rca.... which started color tv.... zenith said we will build color tv better than anyone... once the bugs are worked out.... in 1961... zenith cried uncle... and ordered 50,000 color picture tubes.... from... guess who? RCA..... of course.... but the zenith sets were supposedly overengineered........ therefore the small color zeniths just like the big'uns.... but remember the GE portacolor? their big sets were overgrown portacolors.... because they realized that portacolors were so overengineered that they would work well in anything they built...
My Gripe with these early inline EFL gun zenith tubes is just what you've discovered. The Green gun gets lazy first. Eventually it will start to loose focus, then the drive dies. Beltron seems to do a good job of rejuvenating these - better than my sencore does. Also, they over scan like crazy - especially on the horizontal sweep.
Great to hear your voice again....I worked for a large company that was "right sizing" as they say. Some got emails telling then they were done, pack up and leave. Sort of like getting your walking papers handed to you under that stall in the restroom. I heard it happened, maybe.....Not a lot of good work gets done during those times, people just give up.
Cool! I had this same model of Zenith tv when I was a teenager. My dad bought it new, and then he gave it to me in the mid-‘80s. And, yes, it weighed a ton, like 40 or 50 pounds at least. I remember those picture adjustment thumbwheel type controls on the back.
Brand new when I was working for our local dealer. Just like yesterday to me. You don't see a lot of Zenith most likely because they keep working and the owners want to keep them! Your observation that the H-Out transistor was Toshiba was correct (T Z on it meant it was made for Zenith and is an original part). These types of tuners would have the stationary contact strip warp and we would put a shim behind it to restore a good contact.
So cool to see Zenith guys commenting here. Our Chromacolor lasted over 10 years. Looking for an old one in good cosmetic shape. Don't even care if it turns on. I just wanna stare at it and pretend. I am so sad.
I bought a 19-inch Zenith in 1975. Those plug-in boards were awful. It became a matter of smacking the cabinet at times. My Howard Sams employed brother-in-law tried to work out a solution, but there was nothing that worked. My wife continued to work at Sams for some years, and we bought several sets from the Family Store. My Zenith came from retail. I replaced the Horizontal output transistors more than one using an adequate amount of heat sink compound. I am hooked on your videos. Cheers
I had one of these. My dad had a tv repair shop and somebody brought it in and ended up not wanting to fix it. My dad fixed it and I had this set for a good 20 years before the power supply failed. Damn good product.
This fits in, because the Video You have of the 1952 Magnavox B&W TV was similar to the 1957 Magnavox My Family had until 1975, they bought what I recall was a 19 inch Zenith Color set much like this one. I remember it quit prematurely during a Huge Thunderstorm that burned it out sometime in the Mid 80s. The Color was nice but I remember the B&W Magnavox having a bigger screen!.
@@milesjoyner Sorry, I don't live anywhere near Michigan. I don't even have the time to make a flight or far drive to Michigan. Thank you for the offer though.
Sure thing. I found mine at an old yard sale years back. Opened her up. Dusted her out and she worked like a champ. I’m sure I’ll find a new home for her tho.
Awesome TV! I just picked up a Sony Trinitron KV-8000 and am ready to do a convergence and purity alignment on it. Super scared to break anything. It was manufactured November 1977.
It's incredible that I was born in 09/77, and I've worn out a couple of much newer 13" TVs, one was a Zenith-successor Goldstar. Zenith still has a great picture instead of being dead. Your replacement part had 1975 on your instructions, so maybe the 1977 came with the orange cap.
I think many people may say the same about Packard Bell. My only exposure to the brand was crappy compukers from Best Buy in the late 80's into the 90's.
label at 4:13 says Manufactured Springfield MO USA, so assuming that was the Zenith factory that made this unit. Apparently Bass Pro bought the site when Zenith stopped US production in the '90's
Thanks for the comment about the screen shrinking when the B+ goes low. That seems to be what's happening with my 1991 Emerson 13" set. Probably a bad cap somewhere inside.
Mind numbing, spirit crushing tv programming drivel. My god mate, television really drains my soul. shango you know youre gonna have to buy a super smokeless grill and do some tv EOL's on it.
My 2002 JVC 20" TV/VCR Developed an internal tube arc. I took it to a repair shop. It was beyond repair. I didn't know much about electronics then. But I would guess it might have been a similar issue as this. It was around 2007 before I got my first HDTV.
Probably the tube itself. could have replaced the pic tube, but would have cost as much as a new TV. Back when a 19" color set cost $350 -$400 and rebuilt picture tubes were available for $100 it would have been a viable repair.
GREAT!!!!!!!! 1977 my Birthday, this TV Set Great U.S made staff!. Auweia Jay Lenno Lebt noch lach , The Holzmichel ;-). Please more Sylvania Sets ;-).
Here endeth the lesson. As instructive and entertaining as ever. Channel surfing with Shango is a riot. "Liquid lunch with John Tobacco" 😒. Nice tv set. Cheers.
Hi, I find this Zenith TV line interesting, it has different components such as kinescope, these orange 4-terminal capacitors, it also has those ceramic plates with a row of terminals that I never knew exactly what they are, looks like thick film resistors. I lived in Paraguay, and I notice that imported a small batch of these dated March 1981 TV sets (color broadcasting from that country began that year), once I got from a friend a 13-inch Zenith television that's almost identical to the yours in the outside, but inside was completely different, I remember it was made up of 3 printed circuit boards mounted on a plastic frame, the fly-back transformer was huge and no longer used high voltage tripler. Unfortunately the TV was in very poor condition, and was hit by an lightning, so the repair was not feasible, but I kept some of its pieces as a souvenir. By the way, unlike yours, this TV I got was made in Mexico, but it seemed to have a little of every place in the world inside... I really liked your TV, congratulations!!!
On those CCII sets the chassis tilts back, hinged at the bottom. Loosen one screw at each side at the bottom, then there should be a bracket to release near the top. Easy to access the trippler and that oil cap. Also a bunch of electrolytics back there on the module sockets.
KCAL is blocked because of some silly carriage dispute between AT&T/DirecTV and CBS. All CBS O&O's are "blocked" on DirecTV and U-Verse. All Nexstar owned stations are blocked as well. There's like close to 200 Nexstar owned stations in the US.
We had two of these for customer loaners. Some people liked them so much, They didn't want to return them. The four leaded cap! The HV would shear the neck right off the tube!
ZENITH had outsourced production to MEXICO in 1980 (100 %), before then, the circuit boards were being made in mexico starting in 1978( boards will have the part number on a sticker, with where it was made, also if there is an "R" number after the part number, that is the repair number 1, 2 ,or 3 after the third repair zenith scrapped the board)
I had those bars with a analog rf modulator, I had to replace a filter cap as the esr was way to high and now it's fine. Maybe you just need to replace a couple of capacitors inside the your Jerry Springer box.
I had the 1975 version 19" and I had the 1972 version maybe 73 they looked exactly the same but one still had 4 vacuum tube in it and the other one was all transistor
REAL "STATIC" and "SNOW" (Video Snow) YEAH 😬! Around 22:22 in the video when the RF - signal goes away! How many YOUNG PEOPLE know about THAT today. NOW we get "BLUE - SCREEN" or some pre-programed frame "NO SIGNAL". (Too much "DIGI" today)! 29:48
12voltvids had rebuilt several digital conversion boxes. The digital box's SMPS caps go bad all of the times because of constant use and cheap cap quality. Just a heads up.
Those earlier inline gun Zenith tubes from the late '70's-early '80's were not as durable as the older delta gun tubes and it was usually the green that went first. However, they are still not nearly as bad as the crap from the '90's.
fix it Shango this would be awesome for a retro video game or computer pure RF NICE little old TV for real it was amazing when it was new! I still have the Philco Ford tube 13 inch tube hybrid set from when I was a kid it's modded for composite and RGB and even S video but it's still going and CRT is still strong! It's QUALITY like nothing you will ever find today...
