1997 Hitachi Rear Projection TV Tinkering, Suspended from Workshop Roof!

[@TheOnlyHellGod]

Love these old RPTVs. My mom bought a RCA for $4,000 brand new back in 1994 (she got a nice job the year prior and had just got promoted), and that TV was a workhorse. It was encased in actual friggin OAK. We had it turned on pretty much 24/7 and it didn't die until 2006. Power supply died after 100,000 hours. Bought a 1080i Hitachi DLP to upgrade. Wish we'd have kept the RCA in the garage at least. I played the N64 for the first time on that thing, watched Dragonball Z for the first time on it, watched Star Wars the first time, Jurassic Park, Fifth Element, the Matrix. Irks me when people say these things had a shitty picture or were unreliable. Thank you for making this video and showing how indestructible these babies are!

[@lukedavis436]

Lovely! I love videos about actually fixing and cleaning these massive TVs instead of destroying them...

[@CuriousMarc]

Maybe your CRT tubes might be out of optical alignment. I think I saw some mechanical adjustment for centering and aiming them. You might want to align that first, then correct with the electronics last. Armchair restorer comments of course, I may be completely off...

[@RinoaL]

yeah it was bumped around quite a bit so i plan to tinker with all that later

[@yoloswaggins7611]

240p test suite for your favorite console is really nice to have. I have it for my genesis, really helped me when I was recapping my PVM.

[@tekvax01]

Be careful in the back, those CRT's have a much higher voltage than most regular CRT's. They are around 35 KV, and normal CRT's are 20 to 25 KV at the flyback transformer. You also need an NTSC test signal generator or something with dots and crosses on it, or you will drive yourself crazy trying to tweak it correctly! I've spent days aligning these things! they will drive you completely crazy after awhile! With NTSC, the Green is 59% of the signal, the red is 33%, and the blue is 11%. Just like you said, adjust the green for size, position, skew, pincushion, kerning, linearity, and keystone. Then do the red, and then the blue. Projection TV CRT convergence adjustments are not fun! Make sure you leave it powered on for a couple of hours before you try to adjust anything because as it heats up, the convergence will drift all over the place! www.flickr.com/photos/adinazed/6234282586 I tried to find a half-decent video about CRT convergence, and shocking there weren't many of them... This guy does a sort of okay job explaining it. The purity magnets might help you, but may not. kzbin.info/www/bejne/iX_JZoZ5i82Vack kzbin.info/www/bejne/rnLFoqiZp7x7oLc This one is better... he at least explains all the terms, but it is all computer-controlled and not pots. kzbin.info/www/bejne/aGnFkKdvmcqsiNE

[@TaliaIGhul]

me and my mom use to have one. We bought one in the mid-1990s and it broke down in 2008. Those things were build to last. Had VHS - Blu-ray players hooked up to it.

[@eaglevision993]

To do the convergence right you have to use a pattern generator a DVD with test patterns on it. You start with green and then converge red. Blue comes last and will not converge as good since the blue beam is usually made a little more blurry by design to fill in between the scan lines somewhat. Cover the lens you do not converge at the time for easier visibility or switch of the corresponding color if you have a pattern generator. If you can not converge the colors on the full screen, the capacitors on old convergence boards are often the problem. On more modern convergence boards with digital convergence control, the STK amplifier transistors are 99% the cause of problems. This one seems of the old type with potentiometers so you have to check the voltages of the convergence board first if you have converging problems. But with a gap on the side so big you may also have to check the horizontal output circuits...

[@Raw774]

Just in case you didn't know; the liquid is ethylene glycol, so if you're planning to mess with or disassemble any of the lenses it'd be good to do it over an oil tray or something.

[@wemowmrtporp8166]

This tv looks like it will last longer than any tv sold at Walmart these days , already went through 4 flat screens in 6 years bc power issues. The inside of that tv looks very interesting, I might get one myself if I can manage to find one lol , great video

[@TheChrist11]

Hello. Thank you for this video Just awesome!!! I have a Toshiba 50 1080i DVI Cinema Series RP TV. It only works through the DVI connection. I cleaned the lenses and it looks beautiful!! It has a slight red within the dark scenes… but not too much. Is it possible that I need to down-adjust the red gun a little??? Can you tell me if it’s possible? Thanks for your help. Gif bless you and your family

[@radioazma]

Im curious what would happen if I turn on the picture tubes inside with the mirror projecting onto a wall, do you think it would be safe open it with the front uncovered?

[@RinoaL]

The tubes can only focus to about four feet away

[@davo768]

I am trying to fix my rear projection screen, its only input is labelled RGB via a VGA socket, it used to be part of an arcade machine with lots of burn-in, I'm still hoping it is salvageable.

[@popepaul4438]

That was so interesting always wanted to see how these work and what was Inside very interesting video

[@peterdambier]

Take care of the X-rays. We had a BARCO cinema projector at ESOC (European Space Agency) Darmstadt, Germany and we had BARCO come from Belgium to tune those three tubes. We used it somewhat beside the specifications and they had to increase the amperes for the blue tube. More anode current results in dramatically more X-Rays and we were not allowed to seat people directly under the projector or two meters around. Your roof is high enough and your screen is small enough. There should not be a problem but it is always good to know anode voltage times anode amperes results in Y-rays. Tube amplifiers in Hamradio are as dangerous as video stuff and even good old oscilloscopes are far from harmless. Screening the wooden case with aluminum foil might help to keep all kind of gremlins away. I remember one of those color displays a client had sent back. When I turned it on it was as bright as the sun and I could see things I have never seen before or after. I can imagine what those liquidators might have seen on the roof of the Chernobyl reactor. I am still alive but I dont have children .

I absolutely love your idea! It's so hilarious, but at the same time, I'd love to do such a thing too! The issues with the picture are kinda annoying, but heck! Nothing beats free!

[@garbleduser]

Is the yolk loose on one or two of the three guns? That could cause some of your alignment issues by not being positions to match the other two.

[@danielhall7571]

That music is so nostalgic. I never even had that game but there was just something about the style of the old NES games. I suddenly feel guilty for keeping my old NES tucked away in its box for so many years: I'll have to break it out and let Mario stretch his legs again.

[@dnrk10]

Just a suggestion: if you have a decent sized mirror, set it up so you can see the whole screen from a position where you can easily adjust the controls. I used to do that years ago when I repaired tv's and the controls were in the back.

[@RinoaL]

i actually do have a mirror set up but it wasnt really in such a great position to help.

[@tgamer9159]

Is burn in even possible on a rear projection CRT based TV

[@RinoaL]

yeah it is

[@gphilipc2031]

Can I install a modern projector inside of my CRT rear projection 60" Hitachi? I'm am thinking I would remove the CRTs and associated parts then project onto the mirror or project directly onto the Fresnel lens. Anyone have a contribution of Ideas.

[@RinoaL]

That could work. You could also use an LCD to project with. Get a small 3" LCD and remove the backside so it is transparent, put it where the CRT phosphors are and put a 50W LED behind it. then use the same lenses

[@Adamisgood24]

Will a universal remote work on it?

[@RinoaL]

most likely

[@Adamisgood24]

I have had several in the past.

[@killmore75]

no color wheel in this one?

[@RinoaL]

thats now how these work.

[@WalterKnox]

that is a CRT projection TV, they have 3 different colored CRTs that produce the image, what you are thinking of is a DLP tv which uses a chip with a bunch of little mirrors to make the image and a colour wheel to make the image colour. they also have LCD projection TVs which is just a little LCD panel with light shine through it.

Rin, assuming it has RGB inputs on the back, you could get a VGA or HDMI to RGB Phono adapter from amazon. You could then use your laptop to generate test patterns :)

If you want to brighten up your blue picture tube you likely need to clean the tube and change the tube coolant (glycol). All of them probably need done. I'm also assuming your convergence ICs are dying and that's why you couldn't get the picture dialed in. That's not uncommon, and it's probably why this television was abandoned in the first place. Cheers.

[@LordGryllwotth]

Gonna need to google these kinds of TV's. I have seen projectors that had RGB for showing video on a wall (guess its the same). This TV is using strong CRT and project it! How powerful is that? Must be insane.

My father just go a hitachi 2002 rear-projection tv, and it works fine, but we’re having problems working the input and output. We tried using a dvi to hdmi adaptor to connect it to a roku ultra player, can anyone help?

[@RinoaL]

DVI contains several different formats, some that arent compatible if i recall. but i cant remember for sure.

[@Elias-sn9kl]

@@RinoaL so how can I make dvi compatible to hdmi? Also thank you so much I really appreciate you, I’ve been trying to research how to make the tv compatible with more modern technology and I should probably stick to my strong suit which is biology lol 😂😂

[@RinoaL]

well DVI contains VGA if i recall, if your tv takes DVI but only accepts the VGA, well, then your HDMI-DVI converter probably only steps it down to the digital side of DVI. so you should look into what exactly you have and what signal you need. DVI is like 3 different standards under one port, its weird.

[@Elias-sn9kl]

@@RinoaL I’m confused haha, I’ll keep researching what we need, I keep trying to find more information about the television itself but I cannot find any information on it and I tried looking for the instruction Manual but it is nowhere to be found 🥲😭 I looked online and for videos on KZbin, but I haven’t seen any trying to I guess modernize an old television if that’s even the correct term.

[@RinoaL]

so the dust introduced noise in the signal? i've had a few that had those issues during high humidity.

[@MrBarrymiles]

@@RinoaL think it causes static which interferes with the signals

[@Adamisgood24]

Maybe you can replace the busted capacitors.

[@patprop74]

What better than one CRT screen? 3 of them in one TV lmao, I must have taken 30 of those CRT projector TVs apart over the years, Lots of interesting bits in them, like that Mirror, its a first surface mirror but easy to cut and reuse for other projects, the nice big 3 mm acrylic in back of the lens is useful for laser cutting project, Especially those that have a light black tint to them. the 3 lens assembly are cool too if your really lucky you get the full glass ones but most of the time its in glass and 2 plastics but still the plastic ones are cool to make an engraved acrylic led signs...... and lots of Aluminum to salvage as each CRT screens have an Alu cooling housing full of ethylene glycol.

[@NotSoCrazyNinja]

I miss my NES system, emulators just aren't the same. Any specific games you enjoy for the NES the most? I liked the Castlevania series, Duck Hunt, Friday the 13th, Zelda series, Mario Bros, Solstice, Super Mario Bros series, and Wizards and Warriors II. I didn't have much access to games but managed to find some stashed away in thrift stores back in the 90s. Overall a neat project. I have never had or messed with a projection TV. If you do a custom box for it, you could probably mount it to a wall. Maybe create a sliding mechanism so you can raise and lower it or just straight up mount it. Not sure how much weight your walls can handle like that though, haven't gotten around to watching the videos of you building the workshop lol. If you have access to a welder and some decent welding skills, I can imagine building a mount that will allow you to swivel the TV and angle it and move it close to or away from the wall to get it just right.

[@RinoaL]

tbh i got really burned out on 2d games as a collector, main ones i can get lost in are more rpg style ones. but then when it gets to 3d games i love them like ps1 games

[@NotSoCrazyNinja]

@@RinoaL Ever played Hexen? If I had to point to one old game that I have played the most, it was Hexen : Beyond Heretic. Mostly played it on the Sega Saturn, but found later than it can also be played on PC. For RPG-style games, the one I probably played the most was a game that for the life of me I can't remember the name of lol. It was a shareware game set underground early in the series and later above ground and involved magic and aliens and such. It takes the title as the only PC game I was actually happy to buy. I tend to play open-source or free games on the PC now with some small exceptions. I've mostly been into FPS and sandbox games, never had much chance to play RPG style games. I also enjoy strategy games such as Battle for Wesnoth. If you like 3D FPS shooters, Alien Arena was fun, until every server at the time banned me thinking I was botting lol. Now that I think about it, I don't think I've actually played any games in probably a year or two. The last game I played was Minecraft when I was hosting a server to see how difficult it was to host one. Not difficult to host, but difficult to advertise and get players without spending a lot of money. I have a bad habit of spending too much time playing a game, getting burned out, then either never playing it again or waiting years to play it again. So, to prevent wasting too much time, I just don't tend to play many games anymore. I'm curious, if you had to name one game title that you enjoyed the absolute most, what would it be and what platform was it on?

[@PaulieMcCoy]

Ah, rear projection TVs, first "big screen" I think someone in my family owned. Not sure how much these can be hacked about, since there is literally a projector in there, I'd think it has a fixed focal point or at least not much room to budge and project onto something larger but I'm not exactly sure.

You call it a CRT. I was always under the impression projectors were not CRTs, but I guess the three projectors themselves are cathode-ray tubes?
