When shango is talking about cleaning out TVs, that's usually when he's working on one of his famous "resurrection" sets. Those particular sets are in such a fine balance, from sitting outside in the desert for literal drcades, that an air dusting or brush could feasibly break a corroded wire or circuit trace very easily.

Given that you have disabled the "quick start" feature by removing a wire from the power switch, you might measure the CRT filament voltage, to be sure it's not low. A cathode that isn't hot enough could be part of the reason for the lack of brightness.

That’s a good idea. I was wondering why the working wattage he had it up to (50 Watts) was short 25 Watts of what it was rated for when he read the specs. Might be due to that.

The 1st trinitron was all solid state except for the high voltage rectifier - which was still a vacuum tube. They figured the tube would not likely fail so the big SOLID STATE badge was slapped on the front. I believe 70 or 71 was the year they went to a completely solid state (including the high voltage rectifier) There were some instant on versions of the trinitron, but the EconoQuick CRTs had a fast warmup time due to the different cathode design than the traditional tubes. They were supposed to show a picture within 5 seconds of power on - though full emission wasn't available until about 10 seconds.

My first TV in my 1st apartment bought a 15” Trinitron with the most incredible picture. It was my bedroom set every night well into the late ‘90s. And yeah it was a brick.

I have the predecessor to that set/form factor, the KV-9000U. You didn't have to take out the trim clips, just remove the screws and knobs and the whole case comes off. Oh well, it's done now.

The labor cost of assembling these sets is one of the reasons Sony's cost so much more back in the day. Very complicated sets much more so than the usual TV sets of the period. There were many television shops that would not work on Sony's and others that specialized in them. You could think of Sony as similar to a modern Mercedes-Benz automobile. A quality product that definitely cost more then many of its contemporaries. Unfortunately some of the complexities only added to the repair costs when required. Mercedes-Benz cars have over 100 microcontrollers in various functions all talking to each other. This not only causes complexity in troubleshooting but also in a greater number of failures. Smart people never buy a Mercedes out of warranty as it is not uncommon to find one with dozens of codes set in the computer due to failures of the microcontrollers or what they control. Over engineering is nice but it can be later on very expensive to repair.

I wouldn’t be surprised if this directly inspired the Macintosh and Mac Colour Classic designs (that one used a trinitron tube much like this). You can see the slight wedge shape on the back of the chassis, and the “barrel” shape to the front because of the shape of the trinitron. Very nice find Adrian!

There's no problem blowing out one of these. The old tube stuff might have paper caps that will disintegrate or asbestos you don't want blowing around. The plugs are security plugs and no, they're not critical. We used to drill a little screw in them and rip them out. Picture looks like it needs to be degaussed. I don't care what Sam's says I would try that first. You can even do it with a large magnet or tape eraser. TV has probably been knocked over onto it's right side at some point. I think one of the wires you left disconnected was the degaussing coil. Tube is weak. Probably from instant on feature. Did you try adjusting the screen control on the flyback? You might get it a little brighter. I wouldn't have mucked with the neck board. PSU needs caps. I would start there. I definitely wouldn't change every cap in the set - that's a waste of time on solid state era stuff. This thing doesn't have any paper caps.

Those metal gears look solid.

Funny how they made tube TVs with a quick on feature because people were so impatient they didn't want to wait for the picture to come on, but now with flat screen TVs it takes them 10-15 seconds to get a picture because the little computers in them need time to boot up and show all the splash screens. We've progressed backwards!

Heh, my Vic20 (my first computer, which I still have) was rigged up to one of these (a donation from the family kitchen in 1982) via RF modulator and a barrel to antenna lead adapter. While I still have the Vic (which works perfectly all these decades later), I have no idea what happened to that TV. When I got my C=64, with matching monitor, the Vic went back into it's original packaging (which I also still have), but the TV totally disappeared (I have no memory of where it went next, though nobody threw out a Sony anything back in those days, so it probably went to my older brother, and then off to college with him). For all I know, that's my old TV in the video.

Wow this took me back. I had to fix one of these in the late 70's. The owner gave it to me because it made a scary popping sound. The high voltage transformer or "flyback" was arcing to the chassis. I fixed it by putting some rubber strips and sealing them with anti arc paste on the side of the transformer. It fixed the TV and it had a terrific picture for the time. It worked for years...I wonder what happened to it?

From what I understand, the "DIP" you found at 15:06 refers to the wave soldering direction for that PCB.

Oh yes, I remember in '68 when my parents bought a new TV and it was "Instant On". The old sets would make a crackling sound when turned on if it was cold weather and a wait of a minute or more for the picture to swim into view.

One part is correct in one part is not. They did leave the tube filaments on to prevent failure due to inrush current. Unfortunately the engineers discovered later that the tubes were failing at a very high rate. This was caused by operating the tubes for long periods of time in standby mode without b+ voltage. Special computer tubes were developed that reduced or eliminated this effect. Many computers used 12ax7's or 12au7's and special 6000 or 7000 series tubes were developed that were exactly the same specification as the consumer tubes but with the special cathode that prevented poisoning. These are now sought after by the audio fools and bring sometimes extraordinary prices as they are seen as being superior for audio work.

I think it looks perfect for what it is and the age.. would cool to watch some old tv shows on it..

The CRT heater elements were kept running in order to bring the CRT gun to full emission quicker than if started from cold. Solid state chassis designs, that drove the CRT's, could of start processing instantly, unlike previous thermionic valve (tube) designs which also had to come up to full emission, together with the thermionic CRT thus making "warm up times" seem like eons. The downside of preheat was that this prematurely aged the CRT as the electron gun was still emitting even at the lower heater supply.

Capacitors always the problem with old hardware, suggest replacing them as others suggested. Also suggest cleaning the TV, as Dust and Old electronics causes house fires.

If you can find one, get a Sencore 7000 CRT tester. It was the one of the last and arguably the best CRT tester ever made. The rejuvenation function is also recognized as one of the gentlest available. It has brought many a dead CRT back from the grave. It will rejuvenate computer, television, oscilloscope crt's and even vidicon tubes. They are now selling at a all time low prices as they are not seen to be useful anymore. The instant on feature of many of the older sets was one of the biggest CRT and tube killers. Some of the first computers also had an instant on function believe it or not. The filaments were left on for many hours without b+ voltage. Overtime this would poison cathodes and render the tube useless. Special tube types were developed to prevent this from happening. In the older tube manuals this was mentioned for the computer industrial types but I never remember seeing this feature mentioned for consumer tubes. The engineers of these products never imagined people 40 and 50 or 60 years in the future trying to resurrect these items. They were seen as consumables. Honestly I feel they would be surprised that these items actually survived that long.

I have an early 70s 9" RCA B&W salesman's sample television, built with a mix of tubes and solid state. Its power cord is also incorporated into the back cover, as a safety feature: The idea is that you can't keep the TV plugged in with the back cover removed, so you can't electrocute yourself while swapping tubes. Obviously the consumer wouldn't be working on this Sony like they would with my TV, but I guess Sony still held onto the idea with their early solid-state TVs.
