I've discovered the broken bolts appear to be a pattern problem in this era Sony sets that throws the flyback tuning off killing the driving components. This video is several months old but no less relevant or educational or entertainment for those who need their Saturday morning he's forever playing near blenders usually Oroville flourish lamp
If you get up on Facebook vintage tv forum, I've got a couple Trinnys that show delamination and and PVA rot like mold. I know you picked up a couple of those KV 1722 S. I've got 2 of the same that both have PVA rot starting I've got a 15" that's really bad really bad.. Interesting that PVA rot and delamination are hitting these as well.. Also what seems to be breaking the U bolts I believe are heat cycles (I believe) anyway. Weakest part is the bend. Wrong temper on material. Etc..
You are good person taking care of stray handicapped cats. You are also a good troubleshooter coming from a retired electrical engineer and a former 70's and 80's TV bench tech.
I'm sorry to hear about your gray kitty. He was a good cat. I lost a 2 month old kitten last year and I'm a grizzled old mechanic, but it was a hard time.
Obviously a while back now, but sorry to hear about the other cat. He was a survivor. Really enjoyed this one. The interconnected complexity of these sets is something else. Really impressed you were able to fix this one. Those easily blown up HOTs would have defeated me. Using two zenors in parallel has its own issues. There's always slight variably and one will often end up doing more work than the other. Not that it matters, because later in the video we learnt in normal use they don't actually conduct anyway. And you didn't end up using this board.
Just another Saturday morning drinking my coffee and watching Shango! its nice to get away from all the everyday chaos and watch something entertaining. I work on and repair Industrial electronic equipment everyday and even watching you, I find some of the simple things I forgot about when it comes to diagnosing equipment. Of course old age wouldnt have anything to do with it......Thanks
Sorry to hear about your kitty. I enjoyed his appearances in your videos, especially when he leaves an ant riddled bird carcass for you to enjoy. He loved you.
Youre about more than electronic repairs. You see everything as it is. And live life with curiosity. You live life the best way ever! Ty shango and pls excuse my bad english
Too bad about the gray and white cat, I guess he finally carbon tracked too far. Videos are fantastic and addictive they've taught me a lot in the past few months got my old television running better than it ever has and I've owned it for about 27 years 72 space command 100 19 in color. Changed all the tubes most of them were bad or almost bad, checked cathode current and high voltage both are acceptable it should work for me until it starts blowing capacitors and resistors, hopefully by then I'll be educated enough by your videos to even attempt anything like that.
Yes simplier times in s lot of ways...a lot less technology, but what they had back then was built to last and be repairable. Hence way there are still crts around from 50+ years ago...
This video was highly exfoliating, to say the least! Those Trinitrons are a trip to work on but in the end you get rewarded. I used to have a 27" Sony and it had a great picture. You gotta love modern day tee vee where you can learn how spraying chemicals on your face can bring out your inner vibrancy.
The tape between the transformer core halfs isnt isolation, its to introduce an air gap, said gap decreases the inductance of the windings and increases the magnetic flux density that the core can handle. In other words they can use less core material and less copper wire. If the drive current is too low that could be the gap is too little causing too high inductance.
Great video for watching on a snowy day! I really enjoy seeing you troubleshoot these vintage TV’s with all their faults. Your sometimes comical style keeps you interested in the journey!
we always stared them on a variac , 9 times out ten a big bucket of caps and a bucket of sand to put the flames out they were great sets , we had about 4 of the early kv1810ub ins took as a loan set for customers just big enough to please them and not quite to heavy to lug around , over the years as the lamps went south on them we started replacing replacing the sets with the later version the kv1820 , they were even more sensitive to blowing up the scr and at the time the copy ones were absolute junk so it was always best to use genuine sony ones
Hi bro just learning about electrical circuits, even though I don't have a clue what your going on about, I love the way you talk circuits, explaining what you're doing and why. It just makes sense I feel safe about electrical circuits the way you work,the knowledge and confidence you have shines through, THANK_YOU so much for that please please continue doing what you do... old school is true school. Andy uk
As soon as I saw the thumbnail I thought, that's a SG613 set. I hope it's not bad. Changed many of them in the early and mid 80s. Those sets had an awesome picture for the time.
Things we learned in this video: 1) When the lumisponder stops lumisponding you lose control 2) This is classed as a portable TV, but only if you're a 19 year old body builder 3) These tvs go from being the best when theyre working to the worst when they fail 4) Shango now has an empty wallet due to several trips to the parts store 5) Shango now has an empty wallet due to several trips to the parts store
Sony Trinitron TVs had the best picture on the market. We had a couple different ones growing up. We had one just like this, and a newer one. The second one was from the mid 80s, and was very expensive at the time. I believe we paid around $600 for it. It must have been a rare model because I have never found another one just like it.
Aw man, sorry to hear about your grey & white boy. The black n white looks a lot like a stray who used to come here for a feed (albeit a boy). I remember one video, you were explaining something and all of a sudden just lost your tongue mid-flow & it turned out you'd just noticed a gift one of the cats had bestowed upon you. Cats soothe the soul & their offering of gifts is a good measure of a person's goodness for want of a better word.
I love your videos, and watch them all! I hope you make more really long ones like this, it helped me get to sleep the other night. I only mean that in the very nicest way! I went back the next day and watched the parts I missed.
I learn a lot from this channel. Today I learned not to attempt to mess with old Trinitrons! Hats off to you for getting it going though, I'd have lost my temper and binned it once the replacement board smoked..
My father bought this very model package that came together with a separate Betamax unit. They used to sell both at a discounted price. That was in 1979. We’d never seen those colors before. They were perfect! My father (RIP) always said that LCDs were no match to the beauty of analog Trinitrons, especially this model. He didnt like the sound of CDs either. Now I’m understanding why. I used to record:”Midnight Special” and “Dallas” using our Betamax. My older brother , though, was caught with an XXX rated tape. Oh Boy , my Mom wanted to get rid of that “useless” box right away. Wonderful memories….
Its amazing how finely tuned the flybacks are in these sets but its annoying how it blows out the SCR when no longer tuned. I have a bunch of 70's and 80's Sony TVs and right now they all work. I did have to repair some of them. I remember years ago when I was repairing these a lot of them had dead CRTs. Its true that you must never rejuvenate Sony CRTs but you can do a remove shorts which may bring them back.
I successfully rejuvenated the modern trinitron crt's, the video is usually blanked when the crt goes weak because the jungle circuit cant bias the CRT. The era im talking about is sony late 1990s-2006. Also on projection tubes from this time they liked to have intermittent shorts, tap the neck and watch the color flash and the neck light up inside. Generally for shorted tubes I do the isolated filament trick, wrap a few turns of wire around the flyback and disconnect the filament circuit from the fly. Now the old tubes from this time I don't think its a good idea, strange gun, i tried it years ago on a known weak tube it finshed it off. When sony went to the 3 gun inline gun like everyone else had for years I havent had any issues zapping them, they usually lasted 6 months to a year.....depending on how much they used it.
Yup, this is my experience with Sony TVs. Fix one thing only to find out it grenaded 3 more things somewhere else. Fix those then something else blows. I hated working on Sony TVs
'chain reaction' failure, similar can happen in zx spectrum computers, with lower ram chips, dc-dc converter coil, and its driver transistor ... one bad one can take out the others, replace one of them if bad and if other two bad can kill the new part!
Sorry to hear about old Grey going EOL, the female cat may have worms, but also strays and stressed un-fixed females tend to eat an unexpected amount. If someone got her fixed she’d be three times the size and eating the same
Stray cats almost always suffer intestinal parasites. Not just mainstream worms. Also toxins exposure. Outdoors is considerably more stress, but they can get by decently if fed.
I have a 2000 Trinitron with a jillion hours on it. The jug had gone completely flat about 3 years ago. The CRT heaters run off a flyback winding with a series resistor of about 2.7 ohms. It's on the CRT socket board. Jumpered the resistor so the heaters run hotter. Emission came back to like new, perfect grey scale and beautiful pic to this day. That series resistor seems to be common practice across many brands with flyback-derived heater supply.

I gotta say, you're great at reviving old TV's and junk! I wouldn't have the patience to do it. I didn't even have the patience to watch the entire video and skipped to the good parts.
Shango I was thinking that this set was not going to work.I should have known better.Good job.I made a comment to a Predicta like that Philco used the cheapest components they could get and was told they were fine.His remark.I believe what you said about them.
Back in 74 I went into a store (GLOBE Shopping City) in El Paso Texas and purchased a model TV A bit smaller then that but had the same touch tuning. I was Stationed out at Fort Bliss. We used the TV from then on (it was our first COLOR and our first NEW TV) through my tour with the 3rd Cav then stationed at Bliss, through my tour with The Old Guard in Fort Myer (I lived off base in Arlington Va.) (Mayflower moved it from TX to VA) then in 1977 I was transferred to Minnesota as a recruiter, the TV was moved by Allied Van Lines to Cottonwood MN. and it served us Till I separated from the US Army in December 1977, it was moved by Allied to my home in Lemmon SD. When I settled in with my job as a police officer, we saved up a bit and purchased a bigger set in 1979 and I gave the set to my sister who used it until the flat screens came down to an affordable price in 2012. The set was never serviced, and suffered those moves without breaking. I would say I got my money out of it! They were great sets and the color was unsurpassable even today with the flat screen sets, and mine is fairly expensive JVC set.
the stuff between the core halves would be to gap it and control the inductance, and not to insulate it or stop it making noise. The thickness is relatively critical. curious if they tune those at the factory that way or if it's a standard gap.
Determined empirically, optimized experimentally, then fixed in the design for manufacturing. If you think about it, the core material doesn't change, the winding turns and configuration don't change, so there's no need to tune the gap for each transformer in a manufacturing run.
That was another great video you made! I watched it as my main Saturday night flick. You are one stubborn guy regarding repairing the trinitron or as I thought “ turdatron but you proved me wrong! Great viewing!
My daughter is a cat person. After my good wife passed away a couple of years ago, my daughter moved in to take care of the crippled up man who is her father. With her came a couple of cats! Now about a week after my good wife died another cat person, who rehomes strays brought her a little white kitten with a black spot on his head. One ear was damaged by a cruel dog who picked him up by the ear and nearly tore it off. Now that little guy decided I was his person and has cared for me at all hours, day and night since. The little guy who would fit in the palm of my hand when he came is now over 18 pounds and has all the markings and attitude of the Turkish Van cat. Can't prove he is, and when we questioned some in the van cat talk group they exclaim that NOBODY could come bay a pure breed Van cat as a Stray, they are to valuable for anyone to allow them to hit the streets, even in a large city in the Oil Patch of North Dakota. So what ever he is, he cares for me, keeps me warm, day and night, he is just becoming a pest like those damn black flies that hang around you and you just can't get rid of them. (I think I must be becoming a cat person?)
I’ve been watching Shango66 for 4 or 5 years anyhow. I actually found him watching his old mine exploring vids. I smoked weed, burned alot of brain acreage tripping on lsd , alcohol , rock&roll and all kinds of other shit kids my age did back in the late 60s. Watching Shango do tv repair I just “ zone out” and maybe have a few lsd flashbacks thinking “ this guy is deep”. I sit and wonder who the fu_k designed this sh__ . Ya, 5 years + of watching Shango do this stuff still not understanding what he’s saying and still thinking ‘ this guy is deep’ ✌️😎
O oh oh.... What is that? It's sizzling and popping.... Shango I laughed till I cried. It went crematorium.... Your awesome man keep up your amazing work. Your knowledge is a gift!
My grandma and grandpa had this TV on their farm when I was about 5 or so! I know it sounds funny but I want to just push the channel buttons. I swear I can remember how those buttons feel in my head. When you opened the door on the front in this video, I remembered what that looked like too! My dad used to work on tvs... Well, he built a Heathkit tv and tried to fix them for people he knew or when ours died. I want to say I even remember the inside of the tv because I remember it losing vertical hold when I was like 10 or so and he took it apart.
I had a TV shop when these were not retro. When the SCR and regululator were shorted, knew I was in for a ride. Fixed a few but eventually the price was too high. Later on didn't even continue if the Scr was shorted. I'm in a metro area and would refer customers to the local Sony service center.
I brought Sony floor model that I paid $1.2K in 1983 and my sister trashed it because the repair home service cost is much more than the set worth! I saw the similar set during the trash day in 1999 with the sign "bad power supply". Sony Triton was a smallest Japanese hi-end set that the money can buy back in 1970. The retail cost was $325.00 back in 1972 for 14" set that equivalent to 2.5K to-day with cost of inflation!
One thing I remember about the British Model Sony Trinitron T.V. Sets was that they were so much heavier than the efforts of other companies. People would say that the picture quality was better than the other Colour T.V. Sets of the day which used P.I.L. Picture Tubes.
I've repaired them before I can't compare how difficult they were to repair with other model sets but I will say I blew several scr's through my own carelessness more than one time on the same set.
I love the electronic humor when you roach somthing! I laughed more than once! Interesting video, however, and appreciate the effort to repair this set!!
If the u-bolt is a plated part, I wonder if there's a corrosion issue with the plating versus the thermal cycle and/or magnetic fields? Almost like an electrolysis issue, perhaps? As always, a very educational adventure with a real-world teacher.
I had one of those in the 1980s...a Very good TV for TV DXing...in California I all the way to Montana on channel 3...and Colorado on channel 4....I got 2500 miles max. From My area in Los Angeles...I wish I could do that still.... mine had channel 1-12....I was able to tune it all the way down to 45mhz for Australia and Korea..then I got a All Channel Panasonic later... also for TV DXing too... very good sets to have

i think they break at the weekest point(where the thread ends) and possibly its down to thermal expantion and contraction over 30 odd years
HIGHLY educational. Advanced training.
Working on these sets can be like stepping in the ring with Andre The Giant.
Cheers to you buddy! 🍻 -Al

I'm sorry to hear about your gray kitty. He was a good cat. I lost a 2 month old kitten last year and I'm a grizzled old mechanic, but it was a hard time.
Oh boy! Finally a set from my childhood! My great-grandad had one of these in the front sunroom.
Taka a real man to show his mistakes and explain what he has done wrong.
Sorry for the loss of your cat. It's always hard to loose a pet.
Another interesting and informative video.
Sorry to hear about the loss of your other cat. Far as the bad set goes, who knows what happened to it. Sounds good. Good picture.
Obviously a while back now, but sorry to hear about the other cat. He was a survivor.

This TV was a state-of-the-art back in its time. I wish I could go back to 1979.
High gas prices, out of control inflation, trouble with Russia, incompetent democrat in the White House....... hey it IS 1979!
Oh don't I wish that I could too.

Got it brand new in 79 it lasted for decades, never a problem
You don't normally equate a television and a shattered M6 bolt. A television innards is not the sort of environment you would expect to see that.
Condolences for your loss, the kitty will live in reruns.

2) This is classed as a portable TV, but only if you're a 19 year old body builder
3) These tvs go from being the best when theyre working to the worst when they fail
4) Shango now has an empty wallet due to several trips to the parts store
5) Shango now has an empty wallet due to several trips to the parts store
Some 45 years I had a Sharp C2006 here in brazil and the ressemblence with another brands tv sets and this Sony front panel are really impressive...
A great demonstration of perseverance and troubleshooting. Thanks Shango for the video!
Great video! Working on tv's is better than anything on tv.
Thanks for this video. It reminded me I need to exfoliate.
Watching you exfoliate a TV is a great way to start the weekend

I have a 2000 Trinitron with a jillion hours on it. The jug had gone completely flat about 3 years ago. The CRT heaters run off a flyback winding with a series resistor of about 2.7 ohms. It's on the CRT socket board. Jumpered the resistor so the heaters run hotter. Emission came back to like new, perfect grey scale and beautiful pic to this day. That series resistor seems to be common practice across many brands with flyback-derived heater supply.

Back in 74 I went into a store (GLOBE Shopping City) in El Paso Texas and purchased a model TV A bit smaller then that but had the same touch tuning. I was Stationed out at Fort Bliss. We used the TV from then on (it was our first COLOR and our first NEW TV) through my tour with the 3rd Cav then stationed at Bliss, through my tour with The Old Guard in Fort Myer (I lived off base in Arlington Va.) (Mayflower moved it from TX to VA) then in 1977 I was transferred to Minnesota as a recruiter, the TV was moved by Allied Van Lines to Cottonwood MN. and it served us Till I separated from the US Army in December 1977, it was moved by Allied to my home in Lemmon SD. When I settled in with my job as a police officer, we saved up a bit and purchased a bigger set in 1979 and I gave the set to my sister who used it until the flat screens came down to an affordable price in 2012. The set was never serviced, and suffered those moves without breaking. I would say I got my money out of it! They were great sets and the color was unsurpassable even today with the flat screen sets, and mine is fairly expensive JVC set.
Hi Shango0. Always a good Saturday when you post. Went from tee shirt weather to Snow and high winds,here in the upper east. All my best.
We went from 70-80's then to upper 20s with a windchill in the teens. Next week we return to early spring. Texas
Incredible educational journey! Thank You!
r.i.p gray cat. Gray cat went EOL.
Your amazing at fixing these relics man... but the problem is....... I don't want to watch TV anymore.
Thanks for this exfoliating video.
I like the ones that turn out to have a cascading failure, they make for very interesting videos.
And in the end together we all watch TV... Respect.
These videos have taught me to avoid 70s Sony TVs...what a mess.
Exfoliating. Eye serum is not just for breakfast any more. Good video - - - Loved it . . . loved the cat, too. Peace out.
the stuff between the core halves would be to gap it and control the inductance, and not to insulate it or stop it making noise. The thickness is relatively critical. curious if they tune those at the factory that way or if it's a standard gap.
Determined empirically, optimized experimentally, then fixed in the design for manufacturing. If you think about it, the core material doesn't change, the winding turns and configuration don't change, so there's no need to tune the gap for each transformer in a manufacturing run.
That was another great video you made! I watched it as my main Saturday night flick. You are one stubborn guy regarding repairing the trinitron or as I thought “ turdatron but you proved me wrong! Great viewing!
The thing that I remember from theses sony tv set is how heavy and complicated they were in comparison of others brands. They were realy heavy.
It is amazing how the game of Whackamole parallels fixing this set.
Cats and TVs, Perfect for me.
My daughter is a cat person. After my good wife passed away a couple of years ago, my daughter moved in to take care of the crippled up man who is her father. With her came a couple of cats! Now about a week after my good wife died another cat person, who rehomes strays brought her a little white kitten with a black spot on his head. One ear was damaged by a cruel dog who picked him up by the ear and nearly tore it off. Now that little guy decided I was his person and has cared for me at all hours, day and night since. The little guy who would fit in the palm of my hand when he came is now over 18 pounds and has all the markings and attitude of the Turkish Van cat. Can't prove he is, and when we questioned some in the van cat talk group they exclaim that NOBODY could come bay a pure breed Van cat as a Stray, they are to valuable for anyone to allow them to hit the streets, even in a large city in the Oil Patch of North Dakota. So what ever he is, he cares for me, keeps me warm, day and night, he is just becoming a pest like those damn black flies that hang around you and you just can't get rid of them. (I think I must be becoming a cat person?)
I’ve been watching Shango66 for 4 or 5 years anyhow. I actually found him watching his old mine exploring vids. I smoked weed, burned alot of brain acreage tripping on lsd , alcohol , rock&roll and all kinds of other shit kids my age did back in the late 60s. Watching Shango do tv repair I just “ zone out” and maybe have a few lsd flashbacks thinking “ this guy is deep”. I sit and wonder who the fu_k designed this sh__ . Ya, 5 years + of watching Shango do this stuff still not understanding what he’s saying and still thinking ‘ this guy is deep’ ✌️😎
O oh oh.... What is that? It's sizzling and popping.... Shango I laughed till I cried. It went crematorium.... Your awesome man keep up your amazing work. Your knowledge is a gift!
My grandma and grandpa had this TV on their farm when I was about 5 or so! I know it sounds funny but I want to just push the channel buttons. I swear I can remember how those buttons feel in my head. When you opened the door on the front in this video, I remembered what that looked like too!
My dad used to work on tvs... Well, he built a Heathkit tv and tried to fix them for people he knew or when ours died. I want to say I even remember the inside of the tv because I remember it losing vertical hold when I was like 10 or so and he took it apart.
Now that one ☝️ very nice crt tv probably on of the best ones ever made the picture is as good if not better than a 2002 hd crt 🧐👍
I had a TV shop when these were not retro. When the SCR and regululator were shorted, knew I was in for a ride. Fixed a few but eventually the price was too high. Later on didn't even continue if the Scr was shorted. I'm in a metro area and would refer customers to the local Sony service center.
R.I.P grey & white cat 😿😿
Lei è un bravissimo tecnico.
I brought Sony floor model that I paid $1.2K in 1983 and my sister trashed it because the repair home service cost is much more than the set worth! I saw the similar set during the trash day in 1999 with the sign "bad power supply". Sony Triton was a smallest Japanese hi-end set that the money can buy back in 1970. The retail cost was $325.00 back in 1972 for 14" set that equivalent to 2.5K to-day with cost of inflation!
I've got among others a 1937 RCA 812K console that cost around $126.00 back in the day. In today's money it'd cost $2483.00
Very nice. Makes me wonder why you held onto the video for months before posting it.
One thing I remember about the British Model Sony Trinitron T.V. Sets was that they were so much heavier than the efforts of other companies.
People would say that the picture quality was better than the other Colour T.V. Sets of the day which used P.I.L. Picture Tubes.
I've repaired them before I can't compare how difficult they were to repair with other model sets but I will say I blew several scr's through my own carelessness more than one time on the same set.
Great video, great repair.
Thanks for messing with the old flyback too, I was curious if it was JUST the bolt, and what difference that made.
Guess those bolts were a bit too thin, great video again.
Man, that was harsh, would have given up, many times~ wowee, sir~quite impressive~
I love the electronic humor when you roach somthing! I laughed more than once!
Interesting video, however, and appreciate the effort to repair this set!!
If the u-bolt is a plated part, I wonder if there's a corrosion issue with the plating versus the thermal cycle and/or magnetic fields? Almost like an electrolysis issue, perhaps?
As always, a very educational adventure with a real-world teacher.
I had one of those in the 1980s...a Very good TV for TV DXing...in California I all the way to Montana on channel 3...and Colorado on channel 4....I got 2500 miles max. From My area in Los Angeles...I wish I could do that still.... mine had channel 1-12....I was able to tune it all the way down to 45mhz for Australia and Korea..then I got a All Channel Panasonic later... also for TV DXing too... very good sets to have
That set was ahead of it time.
I had that tv growing up thats a awesome save it was my dads baby
Another great informational educational informative video as usual. Keep up the good work I really enjoy it
