The shrapnel/projectile index of this EOL is epic. The Sony shadow mask can often be heard singing as the tube operates. It comes from the individual wires vibrating
Over the years, I've had several Sony sets like this and most had weak picture tubes. I recall one that looked like brand new, from a cosmetic standpoint, but the R and B guns were dead, while the G tested like new. Raising the heater voltage and rejuvenation did nothing for it. With a hot tube, these sets produce an amazing picture, but finding one with a hot tube is a challenge. On the subject of people watching a set with a near-dead tube, I've seen it many times and the owners thought it had a wonderful picture. In fact, I usually wouldn't mess with the picture quality unless they requested because I've made a bad set look good, only to get yelled at for messing up the picture.
As a calibrator, I must state that brighter does not always = better/more accurate picture. If a night scene, from E.T. or such lights your viewing room up like the midday sun, it's time to examine your TV's picture mode, other settings.
Interesting thing with that Sony by 1980 most companies had stopped using slide potentiometers for their television sets. But here Sony carried on with it.
Wow this video was great only Shango can do something like this. We go from the television Resurrection to an EOL video. Those of you who saw this video and music at the end in the EOL portion was the theme from Magnificent Seven
You should get an Emmy for the end of that video. Sat here watching in bed here in the UK last night and it made me grin from ear to ear - for the greater good naturally. Always watch your videos and mentioned you a couple of times in mine as I love your methodical approach to repair. I wouldn't go near a CRT set but I've learnt much in terms of tackling issues with old stuff from watching you. Thank you. Ralph's House!
Epic "EOL" Shango! I had a Trinitron for 18 years with excellent service but then I dropped it and broke the picture tube in half! Oh well I haven't had any set last half that long since! Thanks for posting and take care!
My parents bought a slightly used KV-1915 and that thing lasted forever. It looked almost exactly like this one. It had a fabulous picture. It was very bright and a had excellent contrast, with dark, inky blacks and rich color. When it was about 12 years old, I took it to work one day to rejuvenate the tube and the emission came right up and it had a great picture on it, for about a year.
That was a spectacular EOL. Some people's EOL's make me cringe, because of the parts that could be salvaged. Thanks for making it clear that you were salvaging the useful stuff first.
The aperture grille is under tremendous tension. You can actually play a tune on the wires. That was a revolutionary CRT design which yielded much brighter pictures because of the minimal loss of beam current thru the grille. Thanks for an exceptional EOL!
My grandparents had a 1970s Sears set with those preset selectors and the neon lamp indicator for the preset buttons, "sensor touch" or something like that. Sanyo apparently made the one Sears sold and the thing was a real beast to move around. They gave it to us when they retired and moved away and it worked fine until the early 90s. It was definitely high hour too, as they (and we) watched a lot of television.
Simply magnificent, Seven. Was happy to ship you our Texas mosquitoes this year. I didn’t get a bite all summer. It’s nice to let someone else be chewed alive for a change.
Shango: EPIC -EOL! Actually jumped because I had the volume up. That was AMAZING and well-cut! Nice Job and Video! Anyway, the Monarch VOM was also sold by Radio Shack as model # 22-049, originally $16.95; I know because as a kid I wanted one of those so bad but never got one! I am sorry to say, but I have gotten one years later and all the precision resistors (and they are very odd values!) have deviated greatly from their marked values so they are not wire wound which maybe they did for AC and being able to measure sound at higher frequencies from say a stereo etc. I plan to completely re-do mine using metal-film ganged pairs and trim-pots to replace them. Many of the originals are high in value, so you can parallel meg-ohm level resistors across them in many cases (some you will need to trim, usually the lower-values). However, before you start, place it in the 30uA (0.03mA) range and check the movement for linearity with varying levels of input current. Some of these movements were either bad or can go bad essentially turning it into a 'shelf-queen!' EDIT: Also the extra insulating washers on the 1200V and 3000V can easily break or falloff (depending on the style they installed) so if loose, glue them soon! On the dirty filthy sets, we used to take all manner of electronics (esp. communications sets) to the car-wash and hose them down with soap then rinse them; anything that did not have paper dials or such was fair game--even wood cabinets. We would then shake them off, bring them home and use an air-hose to blow out any water from enclosed spaces. Then we would put them in either the passenger compartment or the trunk and let the sum bake them out. This takes time but many failures like frequency-drifting, high voltage arcing and other faults magically go away, plus they are so much nicer to work on or scavenge the parts. Also, thanks for showing the Trinitron mask and guns; I never saw them 'deconstructed'--LOL! Anyway, again EPIC EOL Video! 73...
Shango, the choice of the magnificent seven soundtrack on implosion was perfect. Bravo, sir! Now that was some cinematography. It’s for the greater good…
Best E.O.L. yet! Way better than watching "King (fake) made" power an a/c, tv and water pump from a windmill made from an old Freon can and a 200 watt ceiling fan!
Continuing education... I was attending customer training last week at a major TV transmission equipment manufacturer. I brought up there is a big gap between what engineers consider a watchable picture and what viewers are willing to put up with. None of the "engineers" in the room had attended a Sgrignoli lecture on ATSC.
I'm convinced those fake repair/restoration videos are using click farms to boost their views; there's no way they have that many legitimate views compared to established channels doing repair/restoration legitimately.
Great video Shango, always a saturday treat when you post a video, out of all the 80's trinitons ive seen, its always the red emission that gets weak before green and blue, green always seems the last one with a tolerable amount of emission, but when the crt is in great shape they do produce a great picture, Andy in the UK
This was the best! Love the ending!! It's for the greater good for sure! Thanks for showing the aperture grill and gun, I never saw the inside of a Trinitron tube.
Never use rejuvenate on a trinitron but you can turn the filament up and do a remove shorts. That will sometimes bring it back without stripping the cathode.
Not only was this the Best EOL Eva, the dissection of the gun at the end was super interesting. I've never seen inside one before, thanks for showing us that.
this is the best restore and Resurrection channel on RU-vid thank you again for all your hard work making these videos , yeah I'm getting fed up now seeing these crap videos of TVs in mud and spark plugs glued on a bit of wood and generating thousands of watts and thousands of viewers and likes😮 thanks again shango👍
Absolutely Great EOL! That beeyotch was getting me extremely furious. An EOL pefectly done and for the "Greater Good". I know exactly how you feel about things. I am just really fed up.
I had a similar tv set as my daily when I was a teenager. It had no Sony branding, instead it was branded UNIVERSUM which was a brand of a catalogue store in Germany back in the day. It had 16 channels instead of 14 like this one, but the design was pretty much the same apart from that. It had a beautiful picture for the longest time. I gave it to my father, who used it in Hungary on the SECAM system there until they converted to PAL. On both systems the set was working perfectly for many years. They only had to convert the audio offset frequency, because Hungary used a different one than Germany.
Loved the video especially the further clarification about the gun assemblies. Its not really easy to find good information about that stuff online either.
Enjoyed the Video as always. The Sony aperture grille has 2 horizontal wires to minimize the vertical ones from vibrating. Some customers would complain about them one they saw it. Nothing we could do about them other than sell them another brand TV. They did have a great picture.
That vertical aperture grill can even become red hot and sag a bit, almost melting when driven too hard. I recall this was easiest to see with an alignment cross hatch pattern with a few bold white vertical lines.
The number of horizontal wires also depends on the size and resolution of the tube. Smaller low-resolution TVs would only need one while large high-resolution computer monitors would have at least two.
Fantastic EOL! The drama, the flaming debris, the Magnificent Seven theme interrupting that malign, unctuous line of bullshit-I wanted to stand and salute. Hell, yes! And so educational, too. I've never seen a Trinitron shadow mask before.
Please, PLEASE confirm that that whole "Greater Good" thing is a spoof, otherwise I'm leaving this planet tonight!!!!!!!!!!! (I'm from the UK, so the irony may have gone over my head................... ?) The tube gun breakdown at the end was v interesting - don't get to see this stuff too often.
Most interesting video thank you. I am a big fan of the old Sony sets. That’s the only brand I used in my house. Most still function just fine, not that I use most of them now. Over the many years I only experienced a couple failures, a couple I was able to repair. Sad the sets are worth nothing now.
two reason i might use a set like that, one is turn the color all the way down and watch it like black and white, or if i were color blind. oh some folks just use a tv for background noise. i realy like your approch to service. thank you
I lovee you,re videos I started to Repair Old Tube Radios because of you im 25 Years Old and live in Switzerland wr don,t have really much old tv,s and Radios not that easy to find them here but sometimes you can find one i destroyed many Radios haha but now im really good and 90% of them work again i hope you keep going with you,re work i watch you,re videos nearly everyday 🙏 thanks for you,re work ita christmas and im at home working on my Tube Tv and watching you,re videos 😂
EOL of magnificent proportions! Interesting to see how Sony made their CRTS, beautiful construction and the pinnacle of tube technology before the flat screens took over.
Finally got some red emissions in the EOL, for the greater good. Really good detail on describing the gun assembly and shadow mask. Those Trinitrons really were robust.
ha, Sony logo at 38:40. My mom's 2001 Sony 36" died a few years ago. I took it to a recycling place and the helper there dropped it trying to get it (all 160lbs of it) off my trailer and the Sony badge popped off onto the pavement from the shock force.
1983 My grandfather gave me this same Sony Set orginal mint condition- The channel presets were push button and manel set w tuned VHF- UHF - on this set you can pull the tab out for each channels pre sets
My crazy grandmas already old tv i remember from the 1990s appears as an upload on shango.. With one of her suicide notes still tucked away inside and everything!
