The only ones I ever found close was Panasonic, but the only ones that can beat most consumer SONY Trinitrons are dedicated PVM monitors, and some SVGA CRT PC monitors.
The thing is the patents on Trinitron technology expired just as we were switching to flat panels. Diamondtrons were just hitting the market and Trinitrons were getting real competition but CRTs were already well on their way to being irrelevant.
Years ago I fixed my wife's 13" Panasonic trinitron clone. That one had a fried flyback trandformer, which took out the horizontal output transistor and its associated emitter power resistor. Easy fix, though unsoldering the flyback off the main PC board was a PITA. Solder sucker and braid helped. At that time the parts were available off the shelf from a jobber. Set still works on a direct-tv, or ATSC converter box. Love watching you fix similar vintage stuff, helps keep this shit out of land fills.
Even TV's like these are becoming sought after, mainly spurred on by the retro gaming community. To think of the amount of them we scraped just a few years ago.... keep up the good work Shango.
I kept a couple of 12" color TV's just for that reason, I knew they'd become collectable because it was just so easy to throw them out when you got the flatscreen
@@donh01965 Yea there still plenty around here in Ireland but I think a time will come when a TV from the 80's/90's will be rarer than a TV from the 50's/60's given the rate at which they are getting thrown out.
Thanks again for taking the time to do video!! The thing that makes your videos stand out is diagnosis. You go through the steps to identify the problem and then fix. Restoration videos are great but they don't help in tracking down a specific problem. Thanks again for taking the time.
Those small Sony tv's have a great picture. I got one for my dad a 15" Sony tv he really liked it. It was easy to roll around so he could watch it close up in the dining room or wherever.
Triniturd nothing, those were superior to anything on the market back then. That's when Sony was special, now it's just another manufacturer. That's a nice picture for such a high hour set.
I've got a 13 inch Trinitron from 1990, what a nice little set that is. Well, picture wise anyway. Carrying the thing makes you feel like it's gonna fall apart and leave you holding the picture tube with the rest of the set on the floor.
Back when made in Japan meant something. Although the Quality of new Sony products is miles ahead of a lot of other brands (cough Samsung, Vizio) in my opinion.
I telling you this tv is better then today’s 4K tv’s. All my old retro consoles would look perfect on this tv with no input lag, in fact i hate to see how everybody has shoved away those crt tv’s for a flat screen tv. I just miss the dynamic light of those older tv’s, on those flat tv’s it just doesn’t look all that dynamic no.
I certainty agree with you, I'd never connect my NES to a flat screen tv. But in terms of practicality to the common person who just wants to watch CBS it does not matter to them. The 2 factors for them are A. Is it wide screen and B. Can I pick up the damn thing when its time to move? I have a early 2000s panasonic CRT in my room and I love it but its a couple hundred pounds.
These type sonys were some of the best built chassis's, the 20 inch versions were work horses, I enjoyed repairing these model series, Sony made them serviceable friendly.

I just dug this little Sony TV out of a cupboard and plugged it in and WALLAH!! still working great! I bought it in 1991 when my travel trailer was hit by lightning and my electricals got fried, LoL! The only issue I have with it, well, not 'it' but the power cord is the wee block at the business end of the cord has broken off somehow leaving two dangerous prongs sticking out (dangerous when plugged into 110v etc.) Now I'm on the hunt for a new power cord. Great little TV folks and I'll add it to my trailer toys again.
two turtle doves and a microphone! that is the parts store of my dreams only two in my vicinity and they prefer you to order onlne at the computer at home or in store then they pick I would much rather select my own parts. I like the trinitron picture tube had one myself years back. thanks for making the video. that board is toasted and roasted.
One of the best ways to dis charge high voltage capacitors is to use a 240 volt ( in Australia ) light glob. Quick and easy, had one on my bench when working on ctv's .
I grew up watching television, gaming and watching VHS and eventually DVD movies on an early 90's 27 inch Sony Trinitron. About 15 years ago when my family made the switch to an HDTV my dad sold the family Trinitron and about nine years ago he bought the same model Trinitron for his bed room. All the Sony TV's that i have used or my family has used have been quality and have lasted for years without issues.
Nice that the original little Sony CRT is still perfect, considering its kind of a high hour set! Good work on the diagnosis and repair, as always very enjoyable viewing!
nice little telly, i have a couple of 10 inch colour crt sets, one had similar psu trouble 😉 , one had bad rubber scan yoke wedges that had gone 'conductive' 😲
No shit, I just got one of these exact TV's for free. It was gonna get thrown out because the front panel was pushed in. I saved it so I can fix it, and I wanted a small CRT, and this one has pretty darn good picture. Although it works just fine at the moment since I got the remote I had working with it, I have taken the shell off and taken a look inside to see what I need to do to get at it. This video is great information!
No manufacturer from that era could touch Sony's picture, RCA tried for years to make a similar crt. That Power supply does run hot so all the lower value caps are "probably" bad and If you didn't do it already you might want to re-solder the HOT & the Horizontal drive transformer. Great video, I watch your channel because I don't work on tube equipment and find it interesting so this was a treat getting to see you work on something from my world.
Those trinitrons are great for watching VHS tapes @ EP speed. Of course that's because they are lower res. But I like that when the source cannot be made better by anything other then that monitor. They are not to be used for testing or calibrating other devices tho.
BTW, Thanks for going to the effort of making these videos, I make a few myself though nowhere as good as yours. It takes time and patience, thank you. 👍
That TV has a very stable picture and as you said the convergence is incredible. I noticed that this TV does do something interesting for a CRT, the picture doesn't grow in overall size with an image with more white in the image. Why is this? Does it have something to do with the high voltage? I've always wondered about that when watching shows on a CRT. It's much more noticeable now since we're used to watching LCD screens which don't have that effect
You nailed it. Lots of white means higher beam current, which drags down the HV. This accelerates the beam less and makes it "softer": you lose a bit of focus but it also becomes easier to deflect, causing the picture size to grow. This is counteracted somewhat by the B+ sagging, causing the brightness to drop and the picture to shrink, but not entirely. Larger sets had what Sony called a "High Voltage Regulator". This wasn't a simple shunt tube like you find in old color sets: The flyback was driven independently of the horizontal deflection and the HV stayed rock-steady. This set isn't big enough to need one, it just has a beefy power supply, probably well over spec for the little tube it's driving.
These have a proper stabilised EHT supply. Some of the old British colour sets, the pye 697 for example on a 26 inch CRT, the picture could vary by upto an inch in size. Very noticeable on Top of the pops, with flashing lights. The ordinary viewer just accepted it.
I really appreciate you doing this videos! You are helping young techs like me understand the history of electronics! I love this so much. THANK YOU SO MUCH. I WISH I COULD BE THERE PAYING YOU to be your assistant.
There was a mod/kit for this problem. I saw a few of these with the same failure years ago. Good fix! Those Trinitrons had an almost "magical" quality about them.
Power supply is an absolute trooper for taking abuse that long. It's a modern miracle it survived for 30 years!!! The components must've been great quality to hold up to all that heat.
Could they spare the one transistor in that psu :) Just a crude switchmode, not even a feedback line to keep the output side correct. Nicely toasted pcb, no jam though :-).
Nice repair video, your a really good tv tech problem solver. I'd like to think i'm learning proper crt tv diagnosing watching your repair vids as i am a box tv fan myself, don't have any tube based sets(although i'd like to) just solid state but still love your channel man! My oldest set is a 1987 Sylvania 9" color portable tv - works great, had it since 1987 too, so its senimental as well to me. Was my main set back then, has a great picture also. Maybe i can find a tube set at one of the antique /thrift shops around town here in the Phoenix area. Anyways, goodday and Cheers! Shango066
Always love your videos. Good down to earth troubleshooting skills, a thing that is rare these days. If it were me I'd have gone with the 1 watt zeners given how baked that PCB was. Maybe even 5 watters if they were not that expensive.
A bit of 80's trivia on this Sony.. these were quite popular among the folks building news helicopters.. Lots of weird mods for power etc. and bezels.. and all that had to be FAA approved. good times.
rain is good, eco friendly washing and all that... after seeing your older videos and giant filter caps I was expecting you to try and get get those 50 watt zeners and in there.. stock sized zener probably too small.. nice picture though!
The Trinitron CRT design produced excellent pictures with fabulous convergence. I have one with a 1987 date code that still works really well. My only gripe is that it only offers composite video inputs, rather than S-Video.
@@raccoon681 I've thought about this. The only problem that I can foresee is that it might be tricky to do the modification and keep the ability to select between video sources with the remote control or front panel video select button. Everything depends on how they're doing the signal routing internally.
ROFLMAO the power switch... oh maaan, what a beautifully simple and plausible explanation (if you are coming from a logic perspective and not a practical one).
That "camcorder" input jack appears to just be for an external antenna. Wonder why it is also labeled camcorder.... :P Triniturd? You have something against Trinitron tubes? I like them personally. Though I guess it's a matter of opinion. I have a 13 inch KV-1393R (made in 89 like that one) with the woodgrain design. So yeah kinda biased towards Trinitrons myself I guess. :P
Got one of these in my possession, only use it to play games on it, really clear sharp image on it, very useful for bringing to any kinda gaming event. Sadly just can’t find any info about this model on my own though.
Your analysis and repair makes me question if the honkin' huge Trinitron that my late parents had from mid-1990 until the early 2000s experienced the same root failure. We took it to a local Sears repair center when it would not power up. About all we were told was that the power supply board had failed, and it wasn't worth repairing. IIRC that was a 32" (or bigger) with two satellite speakers and a center subwoofer that would kick out the jams pretty well. Nearly 30 years ago, good techs were becoming hard to find in our area. Maybe we could have saved it.
these are good to see repaired on this channel as to many of my crt tvs they work just the buttons dont work too well how would you clean the control buttons on the tv?
17:35 screenshot. Item numbers 7 and 9 lol! Great videos as usual. Switch mode power supplies versus linear designs. I wish I could fix them well. I've enjoyed the video another TH-cam'r posted from his "lab." Be well and God Bless.
13:22 I know I'm late to the party, but upon seeing the part number of those diodes, it wasn't but a few seconds later before I found the datasheet. Also, most zener diodes' part numbers will often clue you into the voltage, so we can guess somewhere in the 9-10 volt range, maybe as high as 12 volts. That 10 will usually be it. Likewise, an RD5ES will probably be a 5 volt zener.
trinitron ruled right up till they started making 16:9, then they sucked, like all 16:9 CRT sets. I had a lovely set with Dolby pro logic in the late 90's right up till about 2010 - like this one perfect convergence and geometry - nothing could touch them. we had them in our TV shop and they really stood out against all the other CRT's
Good fix, thanks for the videos. Question, would adding another diode in paralleled help or did you already have enough current capacity to do the job? Looks like SONY didn't have the greatest design. Carl
1989 too new for this channel, welp there goes my hopes there i was thinking we were going up market and doing some work on a 89 set, maybe a mid 90's or last crt tv sold in the usa of that year before they were stopped,
baked and brittle ^^ cool video ! It is better to test a switch-mode power supply with a load, this might be the reason for the 20V instead of 12V on the output. Perhaps you thought of this, too without filming... The distant mounting is good for the pcb but not for the diodes, perhaps it is better to install them without distance, because the cooling over the copper-foil/pcb-mass is better in this way... or using little cooling-stripes... Some diodes are cooled about the wires, thats why these are so thick in 3A-types... In this case this is perhaps without negative effect...
It is so hard for me to believe being around the Vintage TV Community myself how these TVs have any sentimental value but Shango as usual keep the videos coming great work
Love that green on white pcb layout Sony's got going on... I think it beats out Apple's white text on black board for me. I think the only thing I would enjoy more is black pcb with gold text, not sure if that's ever been done though.
Gotta love the picture quality on those old Trinitrons. Nothing could touch them in their day.
what do you mean "in their day" nothing can touch them even now
The only ones I ever found close was Panasonic, but the only ones that can beat most consumer SONY Trinitrons are dedicated PVM monitors, and some SVGA CRT PC monitors.

For a moment I thought about it, until he said "Here we have"
12voltvids has this exact model and did a repair video on it!
13:22 I know I'm late to the party, but upon seeing the part number of those diodes, it wasn't but a few seconds later before I found the datasheet. Also, most zener diodes' part numbers will often clue you into the voltage, so we can guess somewhere in the 9-10 volt range, maybe as high as 12 volts. That 10 will usually be it. Likewise, an RD5ES will probably be a 5 volt zener.
Quality set. Zeners can sure dissipate heat.
trinitron ruled right up till they started making 16:9, then they sucked, like all 16:9 CRT sets. I had a lovely set with Dolby pro logic in the late 90's right up till about 2010 - like this one perfect convergence and geometry - nothing could touch them. we had them in our TV shop and they really stood out against all the other CRT's
Interesting video. Thanks for filming.
Good fix, thanks for the videos. Question, would adding another diode in paralleled help or did you already have enough current capacity to do the job? Looks like SONY didn't have the greatest design. Carl

New shango066.
Yeah
Save it for later.
Sometimes you just can't put it off for later, you have to rip into it as soon as it appears in the feed.
1989 too new for this channel, welp there goes my hopes there i was thinking we were going up market and doing some work on a 89 set, maybe a mid 90's or last crt tv sold in the usa of that year before they were stopped,
I would like to see new CRT TV's made with a 5:3 ratio because that is what it should have been. At least in my opinion.
I had one. Great little set. Mine took a whole lot of abuse, kept working, until it got hit with a Baseball bat.
( long story 😐).
baked and brittle ^^ cool video ! It is better to test a switch-mode power supply with a load, this might be the reason for the 20V instead of 12V on the output. Perhaps you thought of this, too without filming... The distant mounting is good for the pcb but not for the diodes, perhaps it is better to install them without distance, because the cooling over the copper-foil/pcb-mass is better in this way... or using little cooling-stripes... Some diodes are cooled about the wires, thats why these are so thick in 3A-types... In this case this is perhaps without negative effect...
Thank you for doing this video.
These crts are my no1 favourite, bloody brill shango!
yey! i like modern repairs
One more like from me for a rush in dopamine for you sir!
It is so hard for me to believe being around the Vintage TV Community myself how these TVs have any sentimental value but Shango as usual keep the videos coming great work
Love that green on white pcb layout Sony's got going on... I think it beats out Apple's white text on black board for me. I think the only thing I would enjoy more is black pcb with gold text, not sure if that's ever been done though.
