For discussion and comparision with how televisions are made today, we look at a vintage documentary of 1998 on SONY TRINITRON TV and how was it made. Great views of Japanese SONY factory workers and-Television Electronics; Vintage Documentary Scientific Manufacturing Skills.
This partially restored film is a re-upload of one of several in our vintage television technology series. It provides a great behind the scenes look at factory manufacturing of SONY's famous Trinitron Television screens. Flat screen, CRT (cathode ray tube), high resolution screens. Trinitron screens were used for desktop computers as well as home television sets. SONY's Trinitron was a very successful product, and many are still in use today. Sony Technology Center Pittsburgh.

I worked for Sony in the 80's and serviced these TV's for 30 years, the aperture grill was key to making the Trinitron CRT far superior to any other. If you look carefully all trinitron CRT have 1 or more thin wires from left to right to keep aperture grill from resonating. I replaced the largest ever CRT a 43" CRT it took 4 guys to lift it 440lbs.

So many times I had to pass up even the lower end 32" Sony CRTs because even those-which didn't have the flat screen and so had less glass-were too heavy to find anyone to transport it from the ebay seller to my home. So ~ 6 years ago I lucked into a nicely styled black Toshiba 32". Fantasy: A Sony, or any brand, ~ 48" OLED TV with a 4:3 screen. Then I could view my vintage 1:33:1 content in their native aspect ratio; full screen-AND no cropping!

Low cost up front for modern tvs means ads baked in to the TV firmware, components that need to be serviced more often than older displays depending on usage, and many other factors go into cost. We pay it in the end regardless on if we know it or not

I think we're hitting a wall on price tho at $150-200 low end for a 40ish inch set not on discount. Yeah there will be new screen tech, new materials etc, but at the end of the day you still have to store and ship the bulky box and panel itself, even if its not heavy, a 50in TV is always gonna be a large item

@Username-2 5 ай бұрын

Yet that modern 4K set will have horrible stutter when watching low fps content due to very fast frame response time. Which has to be mitigated with badly tuned motion interpolation, ruining the cinematic motion blur of films. Whereas that old 720p wega would have buttery smooth motion at 24fps. Not everything has gotten better.

Volkswagen closed the plant in the late 80s and Sony took it over about 2 years later. He was part of the initial Sony hires and worked there until the plant closed in the late 2000s. Including the initial tooling, then retooling by Volkswagen, plus the initial tooling and retoolings by Sony, that building has seen some stuff! 😆 When Sony finally closed the plant, they were making 40 - 50 inch LCDs.

Like many other commenters, I also had a magnificent Sony Trinitron television. Mine was a 27" and acquired around 1993. I had it for over 17 years and never had a single issue with it. I sort of regret giving it away, but the thing was rather bulky and awfully heavy. As many times as I've moved, it just became more than I wanted to wrangle. But, I sure loved watching VHS movies on it. Thankfully, I do still have my Sony Hi-Fi VHS VCR -- which also still works like new. It's mostly been packed away since getting rid of the Trinitron in 2010. Once I move again next year, I hope to be in a location where I can stay awhile and finally unbox my VCR. Sony sure made great products. I still have a Sony Walkman that works, too.

It's super interesting to see this 1998 documentary and compare it against the one from Philips made at the end on the 70's (available on KZfaq). In the Philips factory a huge chunk of the process was done manualy by the workers: the glass work, the assembly of the electron gun, it's positionning inside the tube, the welding of the whole assembly, the testing and QC, etc... . Whereas in this one almost every step was automated. I better understand now why color CRTs dropped in price over the years, it was a combination of both the electronic components being cheaper to make and because the manufacturers needed less and less human workers to build them. Interesting indeed 😄

The flat screen model that I had purchased, had a bit of a problem that was most noticeable if the entire screen was to be in red. Instead, the first inch or so on the left hand side would be the proper red, but the rest of the screen was pinkish. So, as a tech, I removed the back and slid out the main PCB since it had this slide out feature. Then I fed a full red screen picture to the TV, and the entire screen was now the proper red. Then I slid the PCB back in, and thus it was located again back underneath the CRT. Now the picture again was as bad as before. The Yoke on the CRT was inducing current on some of the components on the PCB, thus causing a ripple on the +12 Vdc line, a ripple that matched in frequency the horizontal sync frequency, and thus had caused the picture problem. So I connected a wire the GND, wrapped it once around the Yoke, and then connected the other end to the +12 Vdc, via an electrolytic capacitor. This in turn cancelled out the ripple problem, and thus fixed the red screen problem.

@stevebabiak6997 5 ай бұрын

That is called “color purity”. The CRT and yoke would be fitted together, and they would get “tuned” at the factory to operate in their intended geographic destination by placing them into a magnetic field that represented the destination’s Earth magnetic field; the magnetic field of the Earth varies from one place to the next. Because purity is affected by magnetic fields, having nearby electronic devices or motors could disturb the purity. Sometimes the purity could be corrected in the field by rotating magnetic rings found on the neck of the CRT; sometimes other tricks were needed to get the purity to be acceptable.

@helifynoe9930 5 ай бұрын

@@stevebabiak6997 Yep, I fixed another problem in this TV. Some channels had pictures that were all scrambled. All the video info was there, but most of the horizontal signals were higher positioned than what they should have been, and so the TV would lose being in sync with the video. The cable company called these nasty channels, "Pay Channels". LOL Anyhow, for $6 worth of materials, I deigned and built a PCB circuit that fixed those pesky little bugs that were found in those particular baseband video signals. The horizontal sync pulses present within the vertical sync pulse, were still located where they should have been. So my circuit used those to know when to expect to see if the next horizontal sync pulse was in the proper location, and if not, correct it, and then use this corrected sync pulse to know when to look for the next horizontal sync pulse, and correct it if necessary. Anyhow, it just required one LM393 Dual Comparator, one MC1453 Dual Monostable Multivibrator, one MC14066 Quad Analog Switch/Quad Multiplexer, and several transistors, resistors, capacitors and diodes. So it was a line-by-line decoder/fixer. No PLL's required, thus no time delay at all. Pop the board into the TV, and all was well again.

@@stevebabiak6997 In this case, it was the other way around. With the main board slid all the way out for inspection or repair, and thus placing the main board away from the CRT Yoke, the +12 vcd power line was perfectly flat and thus had no ripples at all. But once the board was slid back under the Yoke, the +12 vdc now had significant 15.734 kHz ripples, and those power supply ripples caused video problems further on down the line. The CRT calibration itself was perfectly fine.

@stevebabiak6997 5 ай бұрын

I will guess at the problems and what you might do to repair. The vertical problem I will guess is due to a failed aluminum electrolytic capacitor. Look for a capacitor that has a bulge in the lid or that has popped its lid, or that has vented its contents through the surface that faces the PCB (can sometimes see the mess on the PCB around the culprit). Replace any suspect capacitor. Tuner issues - the broadcast standard in the USA has been changed. This might be the cause, and the solution would be to use an external converter box to modify broadcast signals to the one (NTSC) that the TV was built for.

The bulk of the weight was the actual picture tube itself. Remember, the front surface of that tube was 1/2” plus thick. It needed to be thick to allow the high vacuum inside the tube to prevent imploding.

@stevebabiak6997 5 ай бұрын

@@judd_s5643 - CRTs also produce “ionizing radiation” AKA X-rays; part of the thickness is also due to the need to reduce the radiation that is able to pass through the glass. But you’re correct in the need to be strong enough to hold the vacuum; atmospheric air pressure is just under 15 psi (pounds per square inch), if you had a CRT that had a 25 inch diagonal measure, by the 3x4x5 geometry rule for right angle triangles, the sides and top /bottom would be 15 x 20 inches or about 300 square inches. Multiply that by the 15 psi (because a vacuum is effectively 0 psi, thus the pressure difference is the atmospheric pressure) and you have 4500 pounds of force acting upon that faceplate. The bigger the CRT diagonal measure, the greater that force - implying that even thicker glass is needed. Just to give the readers a perspective that is based on the physics involved.

Interesting if, as the commentary claims, they applied the phosphors between the lines, i. e. only where it was wanted. I visited a Mullard colour tube factory around the 1980s, and there they applied each phosphor to the entire surface, then used a light (UV or IR, I forget), placed not quite where the electron gun would be (because light travels in straight lines, unline the electrons) to fix it in some way, and washed away the remainder. IIRR for two of the phosphors, the washed-away was re-used, because they were more expensive than the third (or it might have been one of the three - I forget, and I forget which was the odd one out). I think the factory was in county Durham, England.

Incredible the work and effort it took to make these CRT tvs. I remember not wanting anything else but a Trinitron TV back in the day. Nothing compared in quality.

The trinitron tube was great, best that was made. Had a dell pc monitor with a trinitron crt in it and it was awesome. The TVs on the other hand suffered from quality control issues. We had a 27" trinitron that had its deflection yoke fall apart. lost convergence massively. One of our neighbours was an ex tv technician and laughed when he saw it. He reassembled and re aligned the yoke only for it to slowly fail again. I repaired it myself some time later and again it was good for a while but slowly failed. Was around this time i lost my faith in sony equipment. It was good stuff but not any more.

I remember my GF had a 19 in Trinitron in 1980. It was fantastic. When we split,she took the TV with her. I mourned BOTH losses. I later had a 26 in RCA. Not as good a picture and a hernia inducer to boot if you moved it.

I didn't work for Sony or at a high-end video store, but I did own a Sony PVM-4300 monitor that weighed over 400 lbs. and had a *massive* 43" diagonal tube. Believe it or not, Sony didn't build any handles or handholds into the case.

I remember as a kid during the late 90s I saw a Sony Trinitron screen and someone's house and was absolutely blown away by the sharpness and the colors on it. We had a color TV at home that was manufactured by Goldstar (I think that was LG before it became LG) and the difference was night and day between the two.
