Overview of the KX45ED1 / PVM-4300 (Worlds Largest CRT)

[@MoreShankMods]

Few fun facts and FAQs: -Yes, I'm using a 100v step down transformer. I also run it through a surge protector, and completely air gap the whole setup when it's not in use. -The TV has 3, yes three, damper wires -I cleaned it after the filming video. I hadn't cleaned it yet at this point as I was considering filming the cleaning process and including it in the main video, but didn't -I have not done a total recap yet -I have not tested PAL, but it makes no mention of PAL anywhere, so I doubt it will work, but I will try at some point. -Allowing random people to see it is tricky because it's not particularly mobile, and bringing strangers to see it is effectively doxxing myself. -I am open to cataracts repair, but it is extremely risky so I am extremely hesitant to do so

[@mrnmrn1]

This is not classic cataract, more like de-lamination. The safety glass itself might be a double layer laminated glass, and its layers might also in the process of de-lamination. Unless you find soneone who have done safety glass removal on Trinitrons, don't ever risk doing it. And if the safety glass itself is bad or breaks during removal, your only option will be to use it without safety glass. I don't think it would be dangerous, the tube surely has an implosion band too, so it won't implode spontenaously, they just added the glass as an extra layer of safety, because due to the huge size, in case of a screen impact the implosion band would probably unable to keep the pieces of the screen together. I would remove the front bezel, carefully clean the edge of the tube and check if there's some sealant around the edge where the safety glass meets the screen. If not, or if it looks deteriorated, I would apply some strong adhesive tape or acid free silicone sealant, to make sure dust won't be able to penetrate between the de-laminating layers.

[@andydelle4509]

You don't need the 100v transformer if the device has a switch mode power supply, which this monitor does. Sometimes there is a jumper wire or switch for 230v but not for 100/120v.

[@Aberusugi]

I would never risk the cataract repair, ever.

[@coyote_den]

I'm not sure that's a cataract. Sony put an anti-glare tint film on those tubes, @RetroTechUSA has pulled damaged/discolored film off PVMs with nothing more than a razor blade.

[@mrnmrn1]

@@coyote_den You might be right, but this is easy to test by pressing the de-laminated part. If it's just a plastic film, it will be flexible on that spot

Definitely do a recap on those power supplies! This is from an era when Sony used capacitors that turn leaky, even in their pro gear. I have a BVM-2010P and it had multiple leaking capacitors in the power supply, a few ELNA and the worst was IIRC a Nippon Chemicon in the -15V power supply. Despite it had only 15V across it, the leaking electrolyte caused carbon tracking and burnt up the board in a half inch diameter spot, which I had to dremel out, it also burnt up the coil of the -15V regulator which I had to re-wind. Replace all electrolytics in the power supplies and go through every board and replace at least every 105°C rated capacitors, those are the most likely to leak. Especially replace every ELNA which has 'Long Life' written on them, those are the worst ever, their electrolyte is super corrosive. Replace every Panasonic caps, even 85°C rated ones. The tiny yellow ELNAs are also prone to leak.

What an insane behemoth of a monitor. Truly the pinnacle of CRT technology and unrestrained hubris. The definition of "because we can"

[@shynodaa]

Not the top. There were 100 hertz TVs with vga, HDMI And the resolution is 720p. In the middle of 2000. Plus a flat screen. So this is not the top of the crt. And this is only the end of the 80s. Not even the technology of the 90s

[@axi0matic]

@@shynodaa It's the biggest CRT ever made. These things have a vacuum in them, so good luck making a flat, widescreen TV this big. The closer to a bubble the tube is, the better. It has a 480p (essentially VGA) input. It doesn't need HDMI. Converting HDMI > VGA is easy, and all CRTs are analogue internally anyway.

[@MoreShankMods]

Be mindful of the limitations of that set. It scales everything that is not 1080i to 1080i, and adds a few frames of latency. If you are planning on using it for 240p retro gaming, it is a very, very bad choice for that.

[@aaronpollock8016]

@MoreShankMods It's mainly going to be used for 6th and 7th generation consoles. I have a kv-27fs100l for the SNES and PS1. It would be interesting to see what those 5th generation would look like on such a big screen

[@MoreShankMods]

Even at 480p, you are still looking at scaling and processing that result in 2-3 frames of latency, depending on the chassis. So depends on the game. Precise stuff like shooters, fighters, platformers, etc will not be a good time, but turn based RPGs would be great.

[@sonycans]

The reason for the 12:30 is that some videos are videoed under low light colour temperature and by adjusting the setting will compensate the picture. That is a reasonable feature in the eighties.

mdp on the remote stands for "mini disk player" , on the back of the tv are jacks for remote controll ur devices throught the tv with the ir remote

In this case, MDP probably actually stands for “multi disc player”, and specifically refers to Sony’s MDP line of machines that could play all varieties of LaserDisc and CD. Some of them could even play both sides of a LaserDisc consecutively without manually flipping the disc over. This TV was made in 1989, whereas Sony didn’t even introduce the Minidisc until 1992.

Sony Trinitrons had a beautful picture. The largest we had was a 27". I struggled to carry it to our local TV repair shop one day - think it needed a capacitor replaced. I had a 36" RCA and I remember the 40" Mitsubishi at the stores. That was the biggest. It was a chore when I had to carry the 36" RCA up and down staircases at around 180 pounds!! Of course these were not professional monitors. That is one, big Sony monitor you got there !!! Was it a popular model in the US ? The slide out/in tuner option is neat !

Dude! I swear I used to have the American version of this, mine definitely had the two component inputs and the tuner. This was about 12 years ago when I was collecting vintage video games. The guy I bought it from made sure to tell me how rare the thing was, that there were only 100 in the US, t definitely weight a TON. At the time I just thought he was doing hat to upsell me the TV and charge me the "vintage tax" on it. I used it for a while but at some point it just stop displaying images, it would still display the OSD but no image on any input. I did some research at the time and it looked like one of the Sony IC's was faulty, I tried to find it but it was completely impossible. Finally I had to dump it when I moved I had no idea it really was this rare, dang. I remember it having a superb picture, even compared to flat screens of the time, never mind vintage games, which yes it was glorious, but also watching movies and such.

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.

[@thomashoppe893]

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.

[@ohger1]

Fun (and annoying) fact on Trinitrons - the bigger they are, the worse the geometry, purity, convergence, and edge focus they have.. They had a "recall" where they replaced the deflection yokes with "improved" yokes to anyone that complained but it didn't help a lot. I quit being a Sony ASC because of all the complaints.

[@UHF43]

That's true for all CRTs, not just Trinitrons. Picture tubes were made astigmatic by design or they just would have been impractically deep. I have a Philips K-40 tv that's impossible to focus on the edges and is only 26" wide.

[@ohger1]

@@UHF43 It's not true for all CRTs, at least not at the level that the Trinitron suffered. Better brands had dynamic focusing to counter astigmatism where the focus voltage was dynamically modulated to match the scan frequency. The flat faceplates had the most trouble with edge focusing, but the Trinitron was worse than most. The RCA Invar flat (almost) with the pre-yammed yoke CRTs were virtually perfect from a geometry, purity, and focus standpoint at 27" diagonal and under, and excellent on bigger tubes all the way to 36" (the biggest RCA (Thomson) made. As far as your Philips, I would have to see it, but there's always some give and take with focus - if yours is fine at viewing distances, it's a good tube. Sure, some customers are impossible to please, but with regard to larger Sonys, I was getting legitimate complaints.

[@UHF43]

@@ohger1 I remember Philips advertised the so-called SCAVEM system, that stood exactly for that: Scan Velocity Modulation. Here in Europe we also had Videocolor that manufactured the PIL-S4 picture tube and had very good convergence, geometry and focus. Then they developed the Super Planar that was a complete nightmare to try to adjust to something bereable. My Philips (one of them) has the 30-AX picture tube, so its early 80's. You can adjust for perfect center focus, but then the edges are really blurry.

[@thardump859]

What does 480p mean? What resolution in dots/pixels is that?

[@FishamanP]

It simply means 480 active horizontal lines per frame, and in this case 60 frames per second. CRTs can take arbitrary horizontal resolution as input, but what detail they can actually resolve is limited by the aperture grille and the density of the phosphor coating, measured in TVL. I'm very curious to know the TVL rating of this tube.

[@MoreShankMods]

Iirc I measured about 600-650TVL, but right now it's bottlenecked by the horizontal convergence. I bet it could be higher with some more tuning.

[@reacey]

Would love to see the cataracts issue be repaired so this tv can be as good as possible, someone like shango066 would be the best person to do something like that. Hes a tv wizard

[@mrnmrn1]

This is a completely different glue compared to what Shango used to deal with, and seems like it is not really degrading (turning hazy and yellow/brown), 'just' delaminating. Not sure if it is removable with heat. I would definitely NOT risk doing it on this unique piece of history, until it becomes really bad. What I would do is to remove the front plastic frame , clean the edge of the CRT and run a very tough adhesive tape around it to seal it, to make sure dust can't get in beween the CRT face and the delaminating safety glass. Maybe it's a double layer, laminated safety glass, and the delamination occours between the two layers of the safety glass, and not (or not just) between the glass and the CRT face. Not sure if any glass company would custom make such curved, laminated safety glass, and even if they do, pretty sure they would deny laminating it onto the CRT. And even if all of this happens, not sure if the end result would be optically right. I guess there would be some hazard of implosion during the removal of the glass, but the higher risk is breaking the glass. If they manage to remove the glass without leaving marks on the screen, they can just use it without it. There's surely an implosion band on this CRT, so it won't implode spontaneously without the safety glass. Sony added the safety glass as an extra layer of protection, because due to the huge size, in case of an impact, the implosion band would probably be unable to hold the pieces of the screen together.

That's too bad about the cataract. I would be worried about the tube glass being strong enough to hold integrity without the safety glass. If you do consider doing it there is a guy in LA that has a channel that deals with removing safety glass.

[@snarkwingduck1302]

Is the protective layer on the glass even structurally necessary? What I mean is, the real reason we need screen protectors on our phone is not to prevent the break itself, but to prevent scratches that will create weak points for the glass to break along when it is actually dropped. I think the same principle applies to this protective coating. There's no way it could be structurally important if it's held on by some weak glue, not in the case of a vacuum tube. Basically you just want to get that nasty old thing off and replace it with a large screen protector. You may want to ask your Sony engineer friends about the structural thing though, just to be safe. I think it's just to prevent scratches though.

The tube is also serial number 3. In my experience, it’s not unusual for the serial number on the chassis sticker, to be slightly different, sometimes by several digits, from the serial number on the back of the unit. It’s just carelessness at the factory, rather than anything more sinister (someone doing a ‘cut and shut’ by swapping bits around). Have a look at another PVM or BVM and you will probably find the same thing.

[@MoreShankMods]

@@MoreShankMods Sony serial numbers are not always consecutive, sometimes a ‘1’ in the serial number sequence indicates a production change or revision, but the ‘1’ is normally closer to the ‘2’ ie 21xxxxx or 201xxxx If over 100 of these were manufactured, then there’s a good chance more are hiding out there, waiting to be discovered.

is the safety glass really that dangerous? if the glass gets evenly and slowly heated (to let the heat go through the thick glass) i would say it is safer, because glass only shatters from stress through uneven heating. you should talk to a glass maker for more informations

With 8T of air pressure on the front (and rear cone), yes!

The first thing I would do would be to clean the TV. But... we are not the same..

[@ygtx44]

same bro

[@youtubehandlesux]

Cleaning the internals is far more important

[@M10000]

You need a point of reference when photographing this TV. Without one, it doesn't look any different from a 27-inch.

[@saskia6750]

I had one,needed 2 people to lft it ! picture collapsed on ours !

[@leretrogeek]

you realy had one ?

[@jongeo]

Wouldn't it be funny if because of this video you discovered another one at an estate sale in your town.

I had a Sony 45" purchased in 1994... it was brutally heavy.... we had to unbox it and lay it in a reclined car seat to get it home from (think it was) SEARS.... at home, it couldn't be carried through the front door (house built in 1931) and we had to lay down a thick carpet and roll it in side over side and it barely passed - no extra room for any hands to be there at all. It sat atop a wooden steroe cabinet and always mushed the cabinet out of square. Once the kids were born, my wife said the risk of it falling for any reason and killing a child was completely unacceptable. It was brought to a Best Buy recycling spot in 2009 or 2010, still working. Kept a Sony approx 42" stored away since I have tons of analog equipment and 4:3 recordings that just look better on CRT than on a plasma at 4:3.

[@ygtx44]

[@thcoura]

Do not fix what is not broken

[@ygtx44]

@@thcoura exact! WELL SAYED SIR

[@ConnorSeals]

imagine how much of a bummer it would be if there were no lag free mode 🤪

[@ygtx44]

not that big of a bummer to be honest crt enthusiast are just used to 0 lag most other types of screens all have lag and i dont think it would be that bad on this too probabbly like 100hz sets wich are not even that bad

[@axi0matic]

@ygtx44 The point is that CRTs are prized by gamers for 0 lag (amongst other things). Would be a shame to ship 100Kg (or similar) from Japan, only to find it had undefeatable 100Hz circuitry. You couldn't play light gun games, for one thing. Though even here, you'd presumably need some kind of zero lag 240p > 480p convertor to get that to work properly. I suppose it would just need to insert a line of black after every 240p scanline.
