So I saw this bad boy being posted about online and decided to order one. They are apparently either NOS Toshio or Sony sets (probably a clone?)

Only 10 bucks, but 26 with shipping.

It's my birthday, a bad one. One that ends in a zero.. so I saw this and bought myself a present.

Wish me luck, I'll update when i see how good or bad this lil cutey really is.

CRTs still live in 2022! It will be fun to see how well it works when you get it.

$26, don't you deserve more than that on your "F-word" or "S-word" birthday? :D

(Or is it an E word or N word?)

Giant "B" and the part number on the PCB scream Sony but
it just dont look Sony. May be a complete Chi-Com copy down
to the markings. Interesting......

Happy BD !

I'd have sprung for the more complete unit.

Dang! I didn't see that! I'd have gone for it.

That's a CCTV and intercom for an apartment or office entrance.

Magnavox had a 4 inch CRT set called an Escort back in '85 or so. I see them on Ebay and there is even an Escort 2. The prices are about what you paid.

It finally came in, with no instructions....

That looks like the same one that Adrian Black on YouTube did a video on:

He has the schematic in his video, which should help you get it hooked up.

Neat. Looks like it's 50hz PAL. Might be interesting getting a NTSC signal into it

I keep seeing more and more of these little black and white CRT tvs popping up all over amazon, alibaba ect. I almost wonder if there is some factory in China that is actually still making them or recently decided to start back up because of renewed interest in CRTs.

I have one of those and it works very very well. I use it to check my modulator system.

Well, it works very very well if there are no magnets around.

Pretty cool..I wonder if the CRT is interchangeable with Sony and other sets with the same CRT size...

Hi to all,

The Chinese 4" flat CRT type 04MC has a TOSHO "made in China" label, see photo.
The Sony 4" WatchMan model FD-40A has a 4" CRT designated as 04JM, see extract from schematic.

Questions:
- does TOSHO manufacture in China using a Sony licence?
- unlicenced clone?

Unless the Sony patents have already run out, i don't see Sony sitting back doing nothing if someone stole their design.
From memory, WatchMans appeared circa 1983, so +20 years forward the patents have indeed expired.

I remember seeing something a while back saying that they would no longer support their analog products. So, most likely, they don't care.

Sony had better things to do like buying out Hollywood and letting their electronics empire go to crap...The Feds should of blocked the buyouts instead of getting their pocket money...

What a shame.....

I'd think the IP rights are obsolescent and basically not worth defending in the age of LCD technology. Sort of like vidicons in the CCD/ CMOS era as limited interest curiosities with limited real utility value.
