I have a few Sony solid state + CRT TV repair manuals like this one: Sony Service Manual Trinitron Color TV KV-1945R RM-701, 54 pages, 1980.
These TVs have all gone to third world countries to be hammered apart and to pollute their water, soil, and air.
So these manuals are now just garbage too, isn't that right? I mean, those TVs were commodity items, like toaster ovens, and no romance to collecting them at all.
thanks- Hue

Somewhere there may be a few people still watching them and a few others in the hands of collectors. But by this point in time, I'd expect that there are perhaps hundreds of copies of service data for each surviving TV.

There are a few groups on FB with people who collect those sets. There may be some interest.
I know that many people refuse to use FB because of privacy issues, but they only require your name, gender, and age.
I don't use a cell phone so I use a web based email address.
Stick to the technical groups, and just block the few trolls.

I've got 9 binders full of Sony TV manuals from the 70s, and 2 bankers boxes of Sony U-Matic and Beta service manuals. 50% of them have been digitized by others and are out there in PDF form - and in my entire time over on VK, I've never seen a request for a Sony manual outside of the small screen color sets - the Chromatron set, and the little 9" and smaller sets, all of which came later than my stash.

The Sony model sets using the SG608, SG613, 2SC867A, and 2SC1034 devices remain unpopular with collectors - for fear of the GCS sweep in them and the misunderstanding that they are difficult to repair. 90% of them suffer bad-cap syndrome. A handful of 160V electrolytics repairs most of them.

The people who go for these sets are the retro video gaming community. Gotta have a CRT to play duck hunt for the NES.

Demand for paper copies of manuals is weird. I went to ARCI in fall with most of the Sam's folders between 100 and 580 (covering years~1950-62) and all the same between ~1900 and 3000 (basically TV only of years ~1979-93).... someone took the newer stuff before the donation auction, I donated the older material and then was asked by the club to feed it into the dumpster after it didn't sell....At the following WARCI meet I had separated my duplicates between the previous 2 ranges and those also met the dumpster after not finding a home being given away.

I have Sony TV repair manuals from the battery sets with hand written notes
by the Sony Service Manager at the time they were popular.

Not that that fact means much, but he came to work for me when the
distributor kicked him to the curb when they decided to replace and refurbish
all products, eliminating the need for the a service department.

Happily I got out radio service and my next career, both wealthier and wiser
when companies were also spinning off divisions deemed as not germane
to their business plan.

Any manual has value if it of use. Trinitron sets were unique, and
perhaps there are enough around that people want, as much as
Westinghouse Refrigerator radios.

I think I do have a couple of Trinitrons somewhere. They were used
with U-Matic Vtrs that the schools used.

if things are digitized, no one wants to lug all those paper copies around. having said that, i do hope that there are a few collections of the paper copies around, just in case the digital copies go up in cyber smoke.

But have they been digitized? If not then the paper manuals should be kept until they are digitized.

It's a shame to throw away original documentation, but it does take up a lot of space. Why not put them on ebay for a token amount? You never know who might want them. 1980 was 40 years ago, so they definitely qualify as vintage.

I actually prefer paper manuals as I don't need to be near a computer and I don't have to worry about a schematic being split in two so it fits properly in a PDF document.
