Opening a rare and expensive DLP tv to look at its parts and investigate how it works. This is one of the most sophisticated TVs I've ever taken apart.
There is an insane amount of complex video processing going on. I can't even imagine the software side of things. Each one of the videos processing chips must be running a TON of code, hence the huge amount of Dram. This tv had a MSRP of $4,700 USD back in the day! ($7,200 in today's money)

Excellent teardown video! I especially liked the detailed review of each component, and the explanation of the colorwheel. Nice job! ~

Thanks so much for watching! I’m glad you enjoyed my video.

WOw man, this is a REAL "teardown". fully appreciate the detail you go into. I'm a design engineer and we're kicking around using DLP so this vid gave me an excellent and fast rundown on what's involved. Well done, and thanks.

Great video! Your explanations are very clear and concise. A very advanced piece of technology too, There is certainly a lot of engineering work that has gone into creating this tv.

I can't believe how much "advanced computer wizz" these TV's have!

@BGTech1 7 месяцев назад

Lol. People who are passionate about electronics make great electrical engineers, and I’m in college to become one.

@@BGTech1 that's awesome 😎. I have a dlp TV I'm converting into a passive 3D projector and then I'm good to use it to play old games I like (like Zelda games and Mario) in 3D. Turns out you can pretty much make any WII and GameCube games 3D using the Dolphin emulator even if they really are just 2D lol.

@@nathanbulle5782 That’s a neat idea. Let me know how it turns out. These TVs were quite expensive back in the day so I’m sure retro games would look nice on one.

@@BGTech1 That's great that you have the curiosity to go through these detailed teardowns. And not just take apart, but try to see how it all worked.

@@BGTech1 it give a good quality with the hdmi but I raise the contrast a little .. it can do 12 by 9 screens no problem…but the image is smaller at the bottom because the angle it is installed

I have the samsung version of this tv. 54 or so inches wide. I removed the screens to use as a replacement back glass for a camper top on my truck then realized its not a good option as it might possibly create a fire hazard with its magnifying glass lens effect as well as no visibility... So i found this video and im astonished at how in depth you dive into this teardown. No fluff or bs. Just straight to the point. So, thanks! Subbed. This seems to be a really unique peice of engineering that i imagine will be a collector peice one day. For now im looking forward to experimenting with the optics to create some kind of artwork. What sort of things can be done using the service ports?

@BGTech1 8 месяцев назад

Thanks for commenting! There are lots of great parts in these old TVs for all kinds of projects. That lens is the fresnel lens, and it’s basically a big magnifying lens. (I demonstrate this in my CRT projection tv teardown video). The ones In CRT projection TVs are a bit more powerful, and people turn them into a “solar death ray”. Good question about the service port, I haven’t tested it so I’m not sure if you need a special tool or not. It’s possible that the tv might need to be put into service mode to use it.

@msylvain59 11 месяцев назад

I never took one of those apart, mainly because they are so bulky to pick up ! Finding just a "bottom assembly" on the street side should be the way to go I guess. Impressive amount of ICs and video processing power.

@BGTech1 11 месяцев назад

It’s definitely a neat piece of technology. Luckily I had space for it!

@shawncalderon4950 11 месяцев назад

You do such an excellent job at explaining every step. May I ask what you do with all of the spare parts?

@BGTech1 11 месяцев назад

Thanks so much! I keep the majority of the reusable parts, and the rest I sell to a scrap yard for recycling.

@shawncalderon4950 11 месяцев назад

@@BGTech1 do you reuse the electronic components for a hobby? I am electronics hobbiest and enjoy high voltage experimints using the tv flyback transformer. Thanks for you quick response!

@BGTech1 11 месяцев назад

@@shawncalderon4950 Yes, I do keep parts for use in my projects. I save a lot of circuit boards for their components, and other useful parts like wire, motors, switches etc. Just about every project I use salvaged parts in some way.
