7:38 all tweeters needs a capacitor, is not a mod from sony, for eliminating humm but for a high-pass filter, it is necesary in any tweeter to work as it should, to reproduce only the high frequencies.
Yeah, that's not for current loop reduction, it's a bare-bones 1st-order crossover. The mid-woofer is probably rolling off naturally at ~6dB/oct (or thereabouts) close to the frequency set by that cap to roll-in the tweeter.
that part reminded me that TV guys usually dont bleed over into audio guys, same with the retro video game guys. Like you dont need to spend $129 on an atari power brick, just buy a normal 5V adapter for $8 lol but they dont know that
Yep I'm starting to doubt his actual technical skills, since in this video he didin't fix anything and simply lost time and money by blanket-recapping the whole thing.
Sony liked to use little magnets stuck to the back of the CRT to compensate for geometry issues, especially in their widescreen sets. Naturally, they'd fall off over time, and you'd often find them stuck to something like a heatsink on the chassis!
When I was a teenager I was in a school exchange with American families (I am French). During our stay in the states, in every living room, there was a huge Sony Trinitron like this one. I remember always being blown away by the brightness, contrast, and vibrant colours displayed. The picture was shining. Never got the same feeling ever since, with any other display technology. Geometry and convergence where the biggest drawbacks of Trinitrons, but man, what a picture...
I've repaired a bunch of tv's back in the day and the static electricity attracted a lot of dust. Like 5 years in a normal living room would probably do what this set shows. Smokers' sets were absolutely the worst. Yellow sticky dust coating everything. Don't smoke, kids.
Hehe well imagine how bars and casinos and well restaruant displays fwiw would have been.. such as where cigarette and cigar tar, also the grease dust that gets airbirne in the back of a restaurant/fast food fry place etc. Lols
Btw I once as a kid saw in a 16ish year old kv32hv600 well a teen in hs not a kid at the time sine I am older than that tv was.. I was a toddler when we got it at sears.. man wish I couldve recalled such a meaningful event., well idk if meaningful but.. cool imho lmfao.. yeaahhh... oh anyways yeah a look of grey dust from at least two different states if not 3 different states that it had been in., oh and it said Made in mexico iirc.. so fwiw it may well onviously had been in a total different country even., fwiw.. but yeah survived one or two moves and went sadly imho to goodwill after the first 16ish years working fine. Fuck, lile literally the flip up rmy187 remote commander units flip up "theater control" glow in dark/luminescent buttons for channel numbers was broke sloghtly on the hinge on one side inevitablmy from my lame af ass being a dumbass kid breaking it being rough ig... I as a toddler hehe put a penny or two in the memory stick slot.. *secretly* and went out and pulled em with a paperclip out as a teen because I was worried itd short something if I left it in and we had an earthqauke or idk.. but yeah one of em said year 03 ie 2003 year us penny.. so I mustve been just barely about 3ish cause I had just turned 3 when I was first on.. well living in a "mainland" household in "Saniago" [San Diego] but really was in hindsight a village or town absorbed called Mra Mesa.. bit my mom used to say I had kept asking "When are we going home.. this is. This is fun but when are we gonna go home" she kept having to explain now we live jere now,. THIS is home.. lmao.. as. Toddler meh not realizing we were not going BACK to Honolulu [HI].. lmao..
So Yeah fwiw Flashlight jsining in looking down through top slots on the right rear when standing behind the set I saw of about a 1 hopefully not more than 1 inch ish of dust inside the set,
I purchased a 20 inch XBR in 1985 with external speakers that were removable. It sat in a corner and I used to point the speakers towards the wall to get more bass. At the time there was a 25 or 26 inch that came mounted on a pedestal with controls you could operate with your foot...I wanted that one but couldn't afford the price. The 20 inch was heavy enough for me to carry but the picture was hands down the most vibrant I had ever seen...I taped Live Aid on VHS and the picture was incredible!
I love gaming retro games on an old CRT. I love the scan lines I love how the CRT blurs the image just a little bit. I love it all. But these CRT's are not being made anymore. They were super common, but now just being thrown out and then there are gone. And if nobody is making new ones, this technology is going to be a lost art. No joke. I repeat, nobody is making these anymore.
There's actually one company that still makes them. I don't remember the name, but they make CRTs on-demand. Sure, they can cost up to $5K, but they're mainly made for museums to begin with.
People have discovered they can sell any crt with composite inputs as a “gaming tv” on eBay for $100 for even a basic crt, don’t worry their value is noted. I kept mine from 2007 as I never liked how 480p games look on an hd lcd non native res
Steve, if you still have this set in the shop, please take a look at the service menu. I have a similar European set. The 32 (or 34 inch here) sets had a special PCB for dynamic convergence (you even mentioned it in the video). This PCB enables features to adjust the corner convergence from the service menu. Very cool tech and I'd be interested if the US units are similar to the EU sets in that regard. The chip responsible is the Sony CXA1526P.
Im a electronic tech and i love sony tv. Especially those big glass crt jobs. Super heavy but made well. I still miss crt tvs. If i could find one in nice shape i would buy it
That was very nostalgic seeing this TV again. We had this TV as the main family room TV for several years. When it became outdated and my family updated the living room tv to a plasma flat screen, my brother and I got this exact TV moved to our room with a "game switcher" so we had the VCR, n64, gamecube, and playstation all set up on this one tv on a huge tv stand. The most fun gaming I ever had!
i once owned a 40inch crt wega, it was 720p and weighed 300 lbs, cost about $2500 it was the best crt i have ever watched plus the audio was so great that it didnt need any additional surround audio, the worst drawback was that you need 4 guys to carry it
@ 07:30 thereabout: Those capacitors are NOT to eliminate Hum, They are used as a High-Pass filter for those mini speakers to act as tweeters. They go self-distruct if you put te full-range audio on them.
The biggest of them all must be the RCA model F38310. With a thirty-eight inch 16:9 CRT made by Toshiba, this monster tipped the scale at 218 lbs. I have one of these, if I could find a replacement for the Focus/Screen control block I'd get it going again, because the contrast ratio and color saturation was superior to any flat panel.
Very cool set, I have a later model XBR, the 32 inch XBR48 with component video in, its one of my absolute favorite sets, but unfortunately I don’t have room to keep it set up at the moment. Would love to have it fully serviced at some point before I put it back in use.
Wow, what a display that is. Always wanted one of these. I did end up with a 36” FD WEGA second hand for free based on me moving it out and away. I ended up leaving it behind due to space, really wish I had it nowadays. Nothing like these old Sony televisions/displays. Nowadays I’m using a free 52” Sony Bravia from 2009, great screen, no internet connectivity.
my grail set....still waiting for one. used to love seeing these at circuit city back in the day. prices that my parents couldnt spend for a kid in middle school though
Oh crap I had one of those! It was so heavy 🤣 Video Concepts was the store, all my friends came over and watched Star Trek Next Generation on it. Awww thanks for the memories
My Trinitron also weighs 185 lb. When I moved into my 2nd floor apartment, I hired two guys solely for the explicit purpose of carrying that TV up the stairs, my back can't handle that anymore.
Trinitrons always sucked for convergence. Have fun sticking magnets! You think this one is bad try the 36" and the monster 40" 4:3 CRT. 385 lbs for that monster. Glad I never have to fix one of these ever again.
@@RetroTechUSA unfortunately when I was working at the Sony dealership I had to work on those bears and believe me they were not fun to work on $385 lb for the 40-in Trinitron so heavy that workers compensation ordered Sony to stop selling them because too many people were blowing out their backs trying to work on these TVs. Even the 36-in was about 300 lb which was still far too heavy for two people to carry but that's what we were expected to do move those bastards up and down stairs I hated them with a passion so much so that I quit that job in 2003 and now I don't have to work on that crap anymore I just have to do audio stuff now for myself but I'm glad to be not having to deal with heavy CRTs
@@x-crisis I refuse to work on one in my TV repair days. Store had sold it it took three guys to bring it into the house 6 months later the TV had broken. If it installed on top of a dresser with custom cabinets in a master bedroom. Told the boss it needed to come into the shop boss told me could not be brought in I had to fix it in the house. I told him good luck it's six feet up on a dresser. Boss expected me to take a ladder turn the TV around so that I can take the back off of it to work on it in a dark bedroom. I said that's not happening and just about got fired over that. From that point going forward the boss figured I didn't want to work and started sending warranty work out. I could just see what would have happened had I tried to repair that in the house something would have got broken and it would have been on me to replace it because the guy I worked for was just that kind of guy. I remember one time about 1985 I leaned into a customer's minivan to haul out their 20-in TV and bring it into the shop as I was lifting the TV out there's dog attacked me grab me by the arm and I naturally jump back and drop the TV which smashed the TV. This was an old set but my boss of the day made me buy the customer a new one because I dropped it even though my arm is bleeding from fangs being sunk into it.
I had one of these in 1993-2002. It was a good set that we used in our great room. It had a wireless headphone that had pretty good audio. I think I paid $2k for it. I was too heavy to move around so we got rid of it.
I remember my mum buying a sony trinitron look similar to this come with full surround speakers including some that unclipped from the side of the tv. U have never seen such a huge box it was a mammoth of a box.
Over the years, I've realized the following for myself: the size of the TV plays a big role. I'm currently very happy with a 14-inch PVM. I like to play 240p content. My favorite systems are NES, SNES and Genesis. The ratio of the picture size to the resolution is the key for me. Also, I've found that very large TVs often bring big problems. Apart from the fact that the weight is often over 40kg. Thanks for the great video and an impression of your world.
Just picked up a Sony Trinitron from October 2006. I’ve adjusted the geometry, and actually got it looking pretty darn even! Convergence is lined up really well too! I always go for newer sets because they have less issues most of the time. Not always though.
I don't know the exact model number (and I'm not about to move it to find out) but I have a HUGE Trinitron XBR that I use for retro gaming with a 36 inch screen that is completely flat and not rounded like most CRTs. It has massive speakers on each side that are as tall as the screen and it can output 720i. Last time I looked up the model number it supposedly weighed about 240lbs (I think). I dread the day it dies, as there is no one near my area that repairs them and I know I'll never find another.
As someone who owned ‘high end’ crt televisions I still recall Imperfect geometry, impossible to totally remove overscan and the edge of the image wobbling when the screen went from very dark to very light
I couldn't see clearly but I suspect the bipolar cap is wired in series, if it is, its there to filter low frequency so that smaller speaker works as tweeter.
Thing of beauty! 😍 I picked up an X Series that, on closer inspection had been used in a doctors waiting room as there was an electrical test sticker on it. The geometry was off on the left so it looked like there was a 1cm black strip down the left side so I ended up selling it on. The picture was amazing though.
Had a variety of these, really a beautiful set. My first Sony was an 20" xbr. Not a bad size back then. 700$ about 2100$ today. The last one was a trinitron with an XBR tube. Nothing like these at the time.
Tyler Esposito’s Dad had something like this with a matching stand back in the day. His channel is called My Retro Life; you need to check it out. He got a 13 inch Trinitron for Christmas, along with a bunch of Sega games in 1994. His Dad was a huge Sony Trinitron fan because his job was electronics.
Kinda wish you had shown off the cleaning process on that tube, it no doubt would’ve been very satisfying lol. But at the same time, I imagine recording and working on this beast is a huge headache.
I bought a 32 inch Sony XBR 32 inch in 1993 and I used an SNES hooked up by an S Video cable to test it immediately - first picture it showed was the Super Mario World title screen. I think mine had the controls on the bottom. It was a great set for its day.
I love curved screen trinitrons! What they lack in sharpness and convergence they make up for in colours, and how nicely they scroll horizontally. Have you tried adjusting the convergence in the service menu? I know some xbrs can be digitally converged.
This is what i have as my primary CRT as well. Just had some staticy horizontal lines show up though. Recapped about half the Defelction caps and replaced the vertical IC. Problem still persists. So im gonna open it back up and see if recapping the rest/some of the daughter boards will clear it up.
a friend and i once threw a 32" Sony Trinitron off a 100'+ bridge. The Trinitron weighed a whopping 172lbs, needless to say that when it finally hit the ground below it sounded like a military grade bomb going off!
I had that exact set. They came with a pair of IR wireless headphones and the remote had a slide switch that also changed the text on the buttons (remote RMY127). It was known as a stand destroyer and I had wished I bought the optional Sony stand instead of using my own. There was also the KV-32XBR85 which had an active subwoofer stand which was out of my price range at the time. Great TV and I wish I had kept it, but moving it was always a nightmare.
No way!! hahaha you played Vivaldi at the end! i already commented about him before i finished watching, then i hear it start playing.. 😂 he's my favorite. i think that's Anne Marie playing your outro if i'm not mistaken. yeah it is absolutely. That orchestra is insane. like a machine. u prob got the audio from youtube it sounds like : ) i've watched that performance hundreds of times
You made a point of recapping the dynamic convergence board, but why didn't you adjust the dynamic convergence settings in the service menu? These early 90s era higher end large Trinitrons had that feature, which isn't often found on SD TVs. Would like to see more consumer TV tune-up content, it would help out a lot of people.
07:37 it serves to filter out the low frequencies since that loudspeaker is a tweeter and can't tolerate low freqs. It's a very basic high-pass filter 6dB/Oct.. Not a mod.
Thanks so much for teaching us precious knowledge. For me, I don't have braveness to open the big television cabinet. Next time, if you still have a chance, would you like to test the sound quality of this television? Thank you in advance!
Pretty sure the center speaker hook up is to use the TV speakers AS your center channel. This is because the integrated sound is so good that many reviewers complained that it’s wasted since anyone buying an XBR will likely have a surround sound setup and won’t be using the TV speakers.
One S-video only? In Europe hings were different. My Panasonic 100 Hz had three inputs of which two supported RGB and two S-video, in addition also front panel S-video. All of course supported composite.
My, my, my...That's a big unit for sure Steve. I would love to have this in the collection. But sadly, I don't have a back like I use to have 20 years ago. But what a beauty it is bro. 8^) Anthony..
As for your taste in classical music.... although I agree... you should extremely consider getting a Sega MegaDrive or Genesis from 1989 to 1991 with the EXT port in the back and "High Definition Graphics" (on the Genesis) and then use certain particular games like Streets of Rage 2, Streets of Rage 3, Sonic 3, Sonic and Knuckles, GleyLancer, Eliminate Down, Alien Soldier, Crusader of Centy, Golden Axe, Ghouls n Ghosts and a few others which used custom sound coding that fully utilized the Sega MegaDrive hardware and FM channels... and play them on that Sony Trinitron XBR... My relative had one of those from that precise year which iirc cost a little around $900.00 USD to a bit over one thousand at a home theater electronics specialty shop in 1995 where I also picked up the little brother of that television which was a Sony Trinitron XR or something but NOT "XBR" As you can see from the inside design details, THAT Sony had special designs to enhance the bass of the sound especially when using either Laserdisc movies or HiFi VHS/Betamax players on S-Video or composite... Also that television came with a wireless headset for privacy of watching a movie, say if you worked at night and didn't want to disturb neighbors while watching a movie that could get loud... That tv also had "Picture in Picture" technology where you could actually split two different channels and iirc you could use the headset to watch one channel while another person watched the other... My model had a more stock PiP mode where it was in the upper right corner and I could switch between audio but iirc it only worked with cable and didn't work with certain cable services because the box handled the channel switching... Still gaming with my television on Super Nintendo, Sega Genesis, NEC Turbo Duo, Sony PlayStation, Sega Saturn and the mighty Nintendo 64 was sheer bliss.. that turned into hypersonic bliss with a S-Video switch box... Which brings us to the Sega MegaDrive Genesis... which can be solder molded to output an S-Video signal which is worth it. It's much sharper than composite and only RGB is supposed to be superior plus with the early TRUE Sega MegaDrive game systems before some hot shot started calling for price cuts and forcing the use of cheaper parts, removing features, etc which is why audio quality goes downhill afterwards and misrepresents the original Japanese design target... it's worth it, very highly worth it... Also technically that particular XBR at 27 inches was LIGHTER than by lower model XR (that also had nice speakers, was a 1996 model and had the buttons on the top too) which felt like you needed to be Hercules to lift... but the image quality and sound... watching HiFi VHS movies, playing videogames... hell, playing Sony PlayStation and Tekken 1, Ridge Racer was insane and later Virtua Fighter 1 Sega Rally Championship 1995 on Sega Saturn because those games have really nice stereo effects. Please do not underestimate the 27 inch CRT size and weight... it's worth it but in the future we live in we tend to over-analyse the tech and fish for flaws... that tv is way better than those smaller PVMs
Ive got a Sharp TV thats of a comparable size. I know it has bad caps or something because it has a butt ton of bloom, but I kind of like that about it. The geometry never looks *quite* right, but it always looks close enough. Although I dont have an issue with squiggles on the lines. At least, not extremely apparent ones like that, just some slight things. Oh and the image is tilted ever so slightly.
What's I'm always amazed to see is that Sony doesn't ship those sets with RGB inputs. I mean they do that for their European versions. Virtually any "living room sized" TV set has an RGB input. They probably even made that set in an European version with SCART socket. Why don't they have SCART and RCA on their upmarket models like this one? I mean this was certainly no penny-pinching TV set.
Short answer is, Scart is a French invention and somehow never made it's way out of Europe. It was not a matter of a set being expensive or cheap. There was and is no Scart outside of Europe.
Those caps on the tweeters are used as hi-pass filters to filter out the low freq from the full range audio signal, allowing only the high frequencies to pass to the tweeters. A simple passive crossover. The value of the cap will determine the cut off frequency. For a high fidelity two-way speaker: the goal would be to find the correct crossover frequency which is between the driver's high roll off point and the tweeter's low roll off point. The same is done when setting up a subwoofer by adjusting the low pass filter frequency setting.
Yes, I just restored a pair of my dad’s old speakers from the 70s and the have a similar 1st order passive crossover setup (although the cap is attached to the inside of the plate where the speaker connections are at the back of the cabinet and soldered to the tweeter wire). The crossover point is around 2khz, above which the woofer is designed to naturally roll off
I think the center speaker input is not to hook up another speaker to accompany the TV speakers, because it's an input. It is when you have a multi channel receiver and you don't have a center speaker, to use the TV speakers as a center channel.
I currently use Sony KV-3400DV2 (1991) 34 inches for my 8-16bit consoles. Also I have JVC TM-H1950CG 19 inches professional monitor for the same things.
