I think the language support hints at what the purpose of these boards is: repairing TVs in parts of the world where the cost of living is very low and incomes are very low. All those videos of people building something new or welding an engine block back together, they aren't just clickbait they are really doing this on a regular basis. Repair culture is at the heart of many low cost countries.

It amazes me that ALL the tremendous R&D effort in television broadcasting on analog CRTs, dating back to the 1920s, finally came down to a board that you bought for $50 bucks which has a built-in game. An amazing 100 years!

That looks like a possible solution to dead CRT based arcade machines. Some of the CRT driver boards for those are full of unobtanium parts (particularly the flyback transformers). This might be a good replacement for the original board.

The thing that kind of boggles my mind is not only does the flyback have the 2023 date sticker on it, but the PCB has a 2021 date silkscreened on it-- meaning that the PCB design was revised that recently! Wild that there's enough demand for CRT TVs and components to be actively developing products in the 2020s.

I remember about 7 or 8 years ago, working on a Mitsubishi 60" rear projection CRT TV from the late '90s. It had RGB convergence issues that I later discovered were the result of cracked solder. I was surprised to find out that, not only did it use convergence amplifiers from the '70s, they were still in production and I got a complete set for less than $20, shipped in under a week!

i'm techician from indonesia, we use many board like that for last stuff if original board can't repair. But we made many replace for elco, because low quality. The problem for that board was for long time use, because can demage your CRT. Your CRT may decrease quality picture. And also flyback low quality may leak in just 1 year use.

The unsung hero for retro gaming right here. Helping keeping crt’s alive for another however many years 😊

I’d bet there’s a decent market for retro gamers.

Well, right after watching this video i ordered one for myself and installed in an old 14" orion tv that had only rf input. I have some bigger trinitrons and two mivar sets (an italian company that made good stuff back then) with rgb input via scart and other fancy thing but every of those tvs come with some sorta of problems. A bigger Trinitron set i own has the shittiest geometry i ever seen (and it's not flat) while the others have grounding issues and are PAL only. Well, with this board and my little orion (used a freshier tube from a Saba set with a Chungwa cinescope) i now have a nearly perfect tiny desk set. The lack of rgb doesnt bother me even if i live in a Scart-main country. The only issue i have with this board is the mono audio but im planning to do a stereo amp mod. I paid 60€ to this beauty and i think it worths every penny. And it's surprisingly plug and play.

A very cool board! Perfect for saving dead TVs and using them for retro sources. A great addition to the channel!

I miss the ingenuity and 'beauty' of CRT TVs, my last one was around 2008, a benemoth HDTV from Sony. I'm glad to see there's still an industry dedicated to maintaining them.

This was one interesting project. You might tap a woodworking shop in your area that has a CNC router and have them make a custom case for this beastie. I have a routed case for my SC126 (admittedly a much simpler project), but it looks beautiful and works very well. Measure carefully, design up what you want, and work with the shop to determine how many pieces you want the case to have (probably a front from one block, a bent or glued-up mid-section, and a back), where you want your control and power ports to be, how you want to mount the CRT and board, and you could turn out a furniture grade piece of equipment. There are woodworking channels similar to Blacktail Studios (they have a YouTube channel) that might be willing to take on a project like this (but all things for a price...) Add a little laser engraving for legends and the ADB logo, and you're off to the races!

If they were to make these boards with RGB inputs then they would have my attention. With how rare and expensive YPbPr/RGB CRTs are getting, this could save people a lot of money and keep normally undesirable CRTs out of landfills.

This vid was way cooler than I expected. It takes up to a year to get over the C human malware. You cold be going along feeling fine and wake up feeling as bad as the worst of the malware. Lot's of rest and fluids even after you feel ok.

When i did computer recycling i sold used monitors for export. The buyer said they were taking the CRTs and adding a board like this to create a tv. He bought thousands of used monitors for a few dollars each. Instant cheap tv.

At 29:45 That function is very useful if you have a satellite or cable receiver and you're listening to the radio. You don't want a screen burnout and turning off your screen to listen to radio is the best option. Modern LED TVs like the Horizon brand have this feature. But i recommend to connect stereo speakers if you have a satellite/cable receiver. In some cases you need an SDPIF-COAXIAL to RCA/Jack converter.

That's so cool. I've got custom driver boards for old 4:3 LCD from old laptops, but I never imagined they'd make drivers for CRTs.

BG/DK/I formats had a lot to do with different audio subcarrier frequencies, 5.5MHz, 6.5MHz and 6.0MHz. Most TVs sold in europe since at least late 80's had 5.5/6.5MHz audio subcarrier detection built in. Some countries used 7MHz channels on VHF bands while other opted with 8MHz channels on VHF, 8MHz was a standard for UHF. Only 5.5MHz audio subcarrier could fit into 7MHz channel. DIgital TV (DVB-T/T2) and digital radio (DAB) finally standarized 7MHz channels at VHF.

We grew up poor in a single-parent household. I always loved disassembly and spent time trying to learn about my devices. Mom not too happy about it and stifled my drive. That didn't stop me though, I'm forever a retro tech weirdo

they probably still make them because they have HUGE amount of pieces already. instead of trashing them, they still making them.. that's my theorie
