I bet there are some Really Rare MicroControllers and Processors on those boards, you may never notice untill you look them up, could be more Processing Power in one of those Chips than there is in a Fully Modified Commodore Amiga or even a 486/586 because a LOT of those "Custom Chips" are Really Extremly Tweaked 6502's or 68K or z80 Processors. Sometimes it was easier to place a FULL ON CPU on a circuit board and just program it to run Clocks and Timings than it was to build the componet based circuits on their own...

The TEAMS of Engineers that designed all of our stuff need a National Holiday for all the Cool Shit they made possible in less than 100 Years (... It's officially been 100 years now guys... Crazy!!"

... I saved one that was Used in an Arcade Cabinet, it was hooked up to a Namco JAMMA + JVI 12 board with Soul Caliber on a PS1/PS2 Main System with Solid State Storgae and both KHz Video Signals were Capable on that model 12 Board, now I know why they used this "Monitor" in there - It was a Real Arcade Machine but I always thought "What the Heck" whenever I saw the MASSIVE CRT they used - I think someone "HodgePodged it togeather" many years ago, but i mean, they did a Great Job.... it looked Factory - I'm almost sure it wasn't tho lol

Thanks for sharing all this information about this CRT. This is a magnificent beast!

This TV is as tall as a 50 inch TV would be.

literally an engineering marvel, i'd love to see one of these alongside other incredible pieces of engineering............ so so neat

Old tellys rock 💪

Why aren't there more out there? Did Sony just make 1 of these? They should be showing up somewhere

Are you certain that the line doubler can't be switched off for 240p? My Sony CRT projector has a built-in line doubler than can be turned off in the menu but the name of the setting is unrelated to the function.

I had a 27" Sony Trinitron from the late 80s. It was in use till 2005 when I bought one of the first Bravia 32" LCDs. It is currently being used as my second monitor. Only downside is that it's 1080i, so I run it at 720p. That remote control totaly brought me back to childhood, 'cos my CRT had a similarily shaped but narrower one, It also had that plastic window compartment. Cheers!

But how loud are the speakers mate

Take a shot every time he says ‘monitor’. Back in my day we called these ‘tv’s’ and monitor was reserved for computers and security camera screens.

are these KX45ED1? kzbin.info/www/bejne/aaq7andpnZd5lZI

Does this monitor accept 576i or 576p modes? Does it decode PAL color video or is it only an NTSC set?

Definitely not the worlds largest.

I’d also like to add, please gather as much info on this as you can from your contacts at Sony. I see you understand that this is a unique and rare item, but I hope that you also understand that this item represents the pinnacle of an entire field of electrical engineering. This is foundational technology, and I can actually foresee a world where CRT development is resumed. (Think of it this way, the US is now re-learning how to build ICBMs to replace the aging missiles in our silos, and these things were designed with slide rules.)

Please dust your TV.

you should really make a crt collection video by this point, or think big and try to open a crt museum of some sort. you yourself got a massive collection (obviously now we know that you also own the literal crown jewel of crts), people like the 8 bit guy who live in texas or linus with the 43 inch ultrawide or the ultra expensive last ever made crt surely would be willing to lend you his pieces for display.

What a crt monstrocity!

DELICIOUS machine. I want one...

Wow - magnetic field of the earth…brought back memories of my Loewe aconda 32’ WS tv, made in Germany and had to be adjusted for Australia

I am surprised the plastic hinges on the boards have not perished. What an amazing piece of tech

I didn't realize you were the same guy as the one who found this monitor and made that fantastic video about getting it over from Japan. I was like, "wait, this guy is just appearing out of nowhere filming the same monitor that he just happened to have lying around?!" Then I realized that I am an idiot. :)

It's like an IMAX screen

All CRT's have a safety glass in case the tube implodes, to keep shards of glass from flying out. Just sayin'.

Anyone else get just a little bit sweaty when he had his hand on the anode or near the neck… still awesome find and so cool that you are preserving this beast…

imagine if someone reversed engine and redesigned all that to be one or 2 boards with modern video processing and everything, it would be awesome and make it much more reliable and simple

This should be in a museum eventually!

I own a 27inch Samsung Dyna Flat CRT. I acquired it in 2000. Excellent convergence, geometric linearity. It also has a tilt feature, turbo sound, component and weighs 110 pounds. I've owned a 20inch Proton, which had a rainbow. My Samsung DOESN'T. It's only weaknesses were over scan. This is the only CRT that I've owned that didn't have a rainbow. $1000 CDN. What about your Sony?

TLDW spoiler: It does NOT turn on!

19:15 You can see the resistor and the board all scorched

I miss the old Sony, not the Soyny that we have today. Also, imagine the CRTs we could have today with modern technologies.

There are people who can fix the screen cataracts -with very little risk and it absolutely should be fixed. This TV should be fully restored.

Unlike most european Manufactures Sony made 23:24 everthing for tve digital Video Processing themselfes. Mostly you see Micronas, Siemens or Texas Instruments DSP's in there at others. In germany we had the KV29FX2000. A great Appliance, but my Back hurts only thinking of it.

I don't have any idea why i originally kept any of my older TV's. Kept a 12 inch black and white tv from my grandparents house that had to be at least from before 1975, have 3 RCA 36 inch tvs from a motel that had built in games like snake. Have an LG from Bosnia that my cousin bought while in the military, 12 inch color TV, but with Tetris built in. Also kept a 60 inch projector tv. In the last couple of years I've had an ich to build a wall of TV's, maybe even take them out of their cases, and arrange them in the shape of a triceratops(anyone else remember tbat Michael Keaton movie where he made one?) None of them are anything like this

I miss the Sony 90s remotes. You look for the green square to power the TV on.

that 21 pin plug thats above the word superimpose is called a scart socket which a scart cable with two scart plugs at each end that plug in the scart socket here in the u.k

How can you repair a television without knowledge in complex impedance, physics and other things like inrush current?

Epiiiiiiiccc. I'm certain that I encountered one of these as a kid (I was born in '90) in England. I was mesmerized by its size, it was the PERFECT basement TV. I remember the feet on the base and the speaker on the side. Sigh....

That is a glorious sight to see, no doubt. Hurts my back just looking at it lol

Surprised that @Sony hasn’t contacted you about this last known unit.

The moment you tell us that this thing is so huge the magnetic field of the earth actually has an influence. Just waited for you to say, yes, the engineers had to considerate the curvature of the earth when designing the tube =)

you need to put a Wii in that spare "rack-mount" tuner!!

The things filthy mate you should give it all a proper cleaning

Will this do 240p?

I was so confused on this was the largest TV because my buddy had a bigger one in 2003. But this is a CRT, not a home tube TV.

Once you get this deep cleaned inside, fresh PSU caps, service menu tuned and colour calibrated, I'd look into adding an extra SCART input that is connected to a subpixel rendering scaler inside the set, directly wired to the internal RGB line, the subpixel rendering scaler board should be a 4X subpixel scale, which will give this set 4 virtual RGB subpixels per physical RGB subpixel, this will massively increase perceived resolution, and negate the fact that it's a larger screen which typically has a lower perceived resolution (subpixel-resolution), the GBS-C internally installed with a SCART output would be a great way to do this, it would also allow for some great extra image options, allow for running 16:9 aspect content in cropped full-screen 4:3 with decent image quality results, reinforce scanlines in desired for increased fidelity, motion adaptive deinterlacing for 480i to 240p or 480p, and if you wanted to, you could even wire in the HDMI as an input for the display, which will give you HDMI in with very decent image quality, which could be very useful for modern sources like Blu-ray, Switch, Laptop or Steam Deck and so on, and whilst your at it, why not internally install an RGB-Pi into the extra RGB input of the GBS-C, for built-in emulation for everything up to 7th gen, with immaculate image quality and processing thanks to DynaRes (RGB-Pi), with the GBS-C, you can also use your smartphone as a remote for the display. As a finishing touch, I'd upgrade the power input to a sine-wave filtered power input module, to provide stable clean power, which will provide the most stable image possible, with the least flickering or interference, which can be an issue with high-powered analogue AV equipment, it will all really help keep the tube as healthy as possible, and the electronics inside will benefit too. And I almost forgot to mention, I'd look into a smoked black tint film, as it really does improve the image and contrast quality of grey glass CRTs, the difference on my Sony PVM-20M4J with a black tint film is profound, it may not be as colour accurate for film editing or other pro uses with a black tint, but the blacks, colours and contrast looks so much better, it looks as good as a Sony Hi-Black Trinitron (black glass).

Top Excellemt........

The luck and triumph involved in getting this 30+ yo rare tv/monitor safely to your parent’s garage from Japan is unbelievable, if this was a book or movie I’d call BS 😂 Right when you find it, they’re about to destroy it and move! I’m here for it all!

Gorgeous!!!😮
