Dar'o What do you mean by old-ish? I have a bunch of CRTs at my house I use VGA on all my monitors. I don't see a big difference between my laptop and my desktop's image quality.
I bought an old portable dvd player back in like 2013 to do exactly this... only problem is, i didn't know how. I'm just now getting back into tinkering and saw this.... this is fantastic!!!
I love, love, love that you posted this!!!! I just bought a Vialta VF-100G Digital Picture Frame for $2 from a local second hand store. It has a 6.8" TFT LCD that uses the exact same Sharp IR3Y29B chip. You just made hacking it super easy, thanks.
What kind of educational experience do you have if you don't mind me asking? I'm currently a third year computer engineering student and I find your videos fascinating.
Hey there, I am a huge fan of your videos! I just want to let you know that I used your raspberry pi game boy tutorials along with your other videos in order to build my brother a retropi game boy for Christmas. it turned out perfectly and I feel as though I've learned so much. Thank you so much for your videos, this is easily some of the best content on youtube.
After i watch this video i found my old portable dvd. That was a sign. I took it apart but i found easier way to plug an external signal. The screen was connected by a 5 pin plug witch 2 pins was video signal and the other two was for TFT light power. I took of the screen and simply cut the wires, then do video and power plug and it works as a portable monitor. I do everything in my way but the idea was Yours ant thanks for that.
ironscull Oh. I have a Memorex MM-8500. I don't know that much about circuits, but I do know how to use a screwdriver, so I took it apart an found out what SoC it had and removed the DVD reader. I want to put the RPi Zero in the empty space and power it using what was for the DVD drive, but if I were to replace the battery - I think it's completely dead - and get an new charger - lost it so many years ago and turned it on with out the Pi, would it overload the PSU?
Love the video - the Goodmans GCE5006DVD uses the exact same circuit boards. I followed your wiring guide and spliced on a video input but kept the casing intact. Very cool
My mom gave me a old one of these and she said it stopped working after it made a loud pop and smoke and I watched one of your videos the said “Before you throw away a TVs check the board” so I did and I saw one of the capacitor Popped and I fixed it and it work so thank you for your videos
Many cheap portable DVD players have LCD screen with only video signal feed. Very simple to use it as monitor for composite signal. The resolution is mostly around 320x240 / 480x240 and not always 800x480. 800x480 is much better picture, but hard to find with only video input. There are less portable players for it. They might use RGB or digital video in (LVDS signal is used in high resolution LCD screens)
You make it look so easy, I def learned something. Here's a project I wanna see done... Take the screen from a MacBook Air and turn it into a slick portable monitor keeping the Aluminum chassis it is housed in.
Fantastic, i found your channel while investigating ambilights for my RPi. looked through your other videos, found this and you have solved a problem ive had for sometime.i wanted to strip out a Mustek portable dvd and drop the RPi in the case, got stuck at the video inputs as i didnt want to use the socket the same as you lol!!. it has a different main board but the screen driver is exactly the same as yours, "Warm up the iron honey, we got solderin to do....."
Great video, love the ideas for retro tech. I'm looking to ad an LCD to the case of my ps4, ideally wired directly to the ps4 so the HDMI port is free for my primary tv. I even thought of adding a crt viewfinder instead, but thats a whole other level of geekery.
This is gave me a great idea to use a banana pi for a lcd I took out of a laptop we were throwing away. It'd make a cool signage device or portable player. Thanks for the idea GreatScott! !
I love your videos you are obviously very very knowledgable in Electronics and computer electronics too. I have no idea what you are talking about when you commentate ( not your English that is fantastic) but about the electronics ha ha ha . I wish I did . Thank you. Baz
I have a portable DVD player from 2006. (Element Electronics PDZ-081E). I bought it on eBay, and I listened to a CD. Also watched a movie or two on it. Yes it is compatible with CDs.
I found your channel just a couple of weeks ago when i found your ambilight clone projekt. I really like your videos, they are very well done!! And i'm looking forward to watch all of them. :) Videos like this is awesome!! Thank you for your work!!!!
Over 3 years later and I would like to see you use it to make a portable RetroPie gaming machine. I know there are videos and guides all over the internet for it but I did like your take on the Gameboy RetroPie and would love to see what you would do for this project. Also, awesome videos back then and still going strong! Hope to see videos of you for a long time!
You are a true genius and are awesome you have shown me most of the things I now know about electronics I should have subscribed much longer you are just a GreatScott!
I am always disappointed to throw away perfectly good components. Consequently I look for things to build using some or most of them. I even try inventing things, some of those stories are very sad. Excellent presentation. They cal me the "Doodeldog" because in early school I would insist on doodeling objects that could work instead of listening to the lesson. I was still a great student, My real name is Don. Cheers!
Hi Scott! Here is a suggestion, please show how we can use logic boards and power boards from a different monitor to fix a broken one! I've got a 25" monitor Hanns G, model HSG1064 which has a logic board and a power board that keep failing. The screen however works fine and the quality of the screen is pretty good. I've kept it in the hope that one day I would learn how to properly transplant a power board and a logic board to make use of the screen. If you don't make a video about this but know of any resources or have some piece of advice please share it with me as a reply to this comment. Thank you very much and keep up the amazing videos!
GreatScott! It just so happens that I have the (almost) exact same thing. The only differences are that it is under the brand name "yukai" and it has a black plastic cover on the bottom.
Your videos are so helpful could you do a video of connecting the disk drive to the Arduino board or whatever board type that is through the pins so you can use disks drive
I still watch vhs dvd and bluray. The greatest actor who every lived was humphrey bogart, and I have a large collection his films and also basil rathbone as sherlock holmes. No format is truly dead, just sleeping
Hey man....so yeah i was searching online for a nice hack to my old 05 philips dvd player...this is great work man...your a genius that knows how to find the correct ic information and searching pathways...excellent work...you did all the hard work for me...i have a small request...can you make it work with fpv? Should be as simple as plugging in input at this point i belive...i really am consolidating as much resources ive had for ages to manufacture my own fpv rc all in one transmitter...you know them all in one transmitters can run 500 upwards to thousands for the agricultural ones🥴i just need one to boast🤣
He was lucky here. Composite video is not widely used for interfacing SoC with built-in LCD so I don't think that you will find such implementation in any phone. I think in modern smartphones it is most likely that you will find LCD with RGB interface connected to SoC without any intermediate controller. RGB signal needs many wires and connector is very small so you would have to make custom breakout PCB for interfacing it to your project (I don't recommend because this will cost more than new LCD with the PCB). Dumb phones sometimes uses LCDs with COG (controller-on-glass). Such controller may be unknown and even with proprietary protocol. So it may require reverse engineering. You could google, perhaps somebody already figured this out in case of your phone model. For example, it is known what protocol and controller is used in Nokia 5110, Nokia 3310... Protocol is well-documented and quite easy to use so these displays are useful. Otherwise, I don't think it is worth spending time here, everything is so small in mobile phones. Perhaps you can try to fix these phones and reuse in other way.
just google the part number followed by datasheet, you will get all available info about the chip, and even info about other versions of the chip, sometimes you get a basic schematic for the more simple chips
Impeccable timing for me, I just started on the exact same project right when your video came out, but had no idea what I was doing. Found your video and now I have a clue! :D I've run into a snag however, I'll look again but the past few times I've looked I can really only find one major chip, the MT1389QE. I couldn't find a datasheet for that exact chip, but found one for MT1389 so I'm hoping it's the same. My problem is I can't find a "video_in" like you (lucky!), and am having a hard time figuring out what all the letters mean to try to find video in. I couldn't find a service manual for the dvd player (Philips PET7402), but found a service manual for other DVD players (Philips DVP4050 and DVP720SA) that use the MT1389QE to try to figure out which pin to use and I'm still lost. Any suggestions?
Took me forever but u can buy a usb to av adapter with software for converting vhs to digital format’ vhs ribbons will go bad over time and deteriorate and like u had a boat load of old family home videos’ the sucky part is u have to sit there and watch the whole thing as it records then hit stop when it’s done etc but in the end so worth it now those memories are mp4 and digital can put on sd card thumb drive etc make a dvd from files etc’ think my vhs to dvd converter was like $13 on eBay this was a few years ago prolly $20 now with everything going up’ but so worth the pay off cause vhs will go bad even just airing unused and those memories r gone for ever something to think about hope it helps bud
@@joshymcdaniel9233 thanks for the information l. I'll definitely look for this adapter. But sadly my VHS player broke I hope I'll find a good one somewhere. But yeah I have some old VHS tapes and the quality of those are really bad hopefully with a new player I can record those old memories.
wonderful! I have asked quite a few computer technicians if I can use a broken down laptop LCD as a desktop monitor, and their answer have always been "no" though in my mind I knew there must be a way...
+Stephen Chen That is completely different. The answer is actually not so much a "no" as a "not easily, and if you have to ask me it means you probably dont have the skills to do it, so I will politely just say no rather than try to explain it to you". I will however take some time to explain it, simplified. The LCD panels in portable DVD players and other integrated devices have multiple components, one of which is a controller. This controller manages the pixel state in the LCD screen itself, which is a fairly intensive task. It decodes the input, works out which pixels need to be changed and writes the new data to the LCD bus. A laptop panel however doesnt have this controller. The video card in the laptop is responsible for performing this task. What this means is that the LCD itself has nothing to decode the input, or change the state of pixels...Now of course you could build a circuit to do this, however it would be cheaper to just buy a screen already made with the characteristics you wanted. There are some third party products for this task, they are limited to lower color settings than you would get from a computer though..and the resolution isnt that great. The issue largely comes from the massive data throughput needed to operate a computer display...each pixel has to be told which color and brightness to display...in the old days when you had windows 95 you might remember 16 bit color, etc...Well for us to control a HD display we would need a minimum of 24 bits per pixel. Some math: 24 bits color depth (considered "true color") Note, this mode doesnt have transparency support. 32 bit is minimum for that. 48 bit is the new 4k format, and has millions of shades of every color. 1920 * 1080 = 2073600 pixels 2073600(pixels) * 24 (bits per pixel) = 49766400 bits to show an image on the screen at minimum color depth. The final piece to this puzzle is the refresh rate. That is how many times per second does the screen update...40 frames a second is considered nice, but 30 fps is totally ok for video playback. 49766400(bits for a frame) * 30 = 1492992000 bits per second to update a standard 1920 * 1080 panel at 30 fps with 24 bit color depth. 1,492,992,000 bits per second = 1492 mbps. Standard adsl 2+ is around 24 mbps Standard HDDs read at about 120 Mbps or 916 mbps So the speed that your computer can read your hard drive data is about half as fast as you would need to run a monitor at minimum...Im not saying its impossible, it isnt...but it would cost a lot, and take a lot of time and effort..and the end result wouldnt be as good as you could get off ebay for 1/100th the cost or less. So as you can see, it takes pretty powerful processing hardware to run an LCD panel...You would be better off trying to hack the video card. Of course that is extremely hard for a variety of different reasons. Hope this helps
+Tyson Popynick Pixel clear :) I do know a little about electronics and does pc tweaking trouble shooting in my spare time and I still wish I could revive some of the dead legacy electronics here at home including a broken laptop with an intact LCD hahah. but very well explained I prolly have to keep things practical.
I have a few old GPS touchscreens for cars. I would like to see you do a video on using those as maybe a portable gaming device maybe make a portable Playstation or Xbox. Or turn a desktop into a portable machine giving you desktop power with laptop mobility. Also want to learn how to run my PC in my car
Awesome Video! I have got a Philips portable dvd player which I would like to mod in the same way. The problem is that I only see a video cable from the main board to the tft board which is labeled RGB (3 wires + ground). Is there a way to input composite video in that case? The main board is a "PET702 DVD BOARD".
Scott,i have an tablet screen and i want to modify it to a monitor for all uses. My problems are two,1:How do i get to know if my 9 inch screen is tft or lcd,2:which monitor control unit should i use
I was looking at using the camera from some old phones. NOT too old, say S3 or S4? I should have a Sony with a true 22 MP camera. My question is, Do these send composite signals or do you have to do some digital decoding? All hacks I find here are about removing the IR filter. Thats nice but a hi-rez camera made to fit my 4" telescope. Thanks for your time.
I've got a control board and a 4.5inch LCD salvaged from an old product display, this seems like an excellent way to put it to use, but how would I adapt it to something like an HDMI input?
It can't be a cold cathode, because cold cathode is a sort of vacuum tube. This is an EL (ElectroLuminescent) pad. Still, good video on a simple and fun project.
Why not getting rid of the other big board and use the Panel alone. When i looked in the datasheet, i saw RGB in. Could you put an VGA-Signal in? Maybe you could use the Display as a small extra Display. I also just kept the screes with boards from old DVD Players, but its really hard to find datasheets for the Driver ics so here you are very lucky you fine one.
Very interesting videos, thank you for making them. I subscribe after the first video but found this one very interesting. I have an older portable dvd player like the one in your video, and I have a question about it. could a port be added even if I had to mount it outside of the case where a usb flashdrive could be used since it can hold several movies rather then packing several dvds for the kids to watch on road trips.
I tried this with another model but the same chip on the driver board but got a gameboy like screen (green background with black pixels). Can somebody help me? Thanks in advance
The S-VIDEO port at the beginning might be just a custom-build non-standard 3.5mm connector of this standard en.wikipedia.org/wiki/S-Video , which connector's shape looks like PS/2 mouse connector in it's normal size
Super, soweit bin ich auch gekommen (mit einem anderen Modeel, als LCD Controller ist der T100A), allerdings Frage ich mich ob dein Display auch ohne daß Mainboard funktioniert, bei mir jedenfalls nicht, da wohl Kommandos via I²C gesendet werden....
As you know dvd players have small amplifier.. I want to run my (big) speakers but they lack volume and power. So I wanna remove the DVD tray completely.. It uses a ribbon cable to a decoder board, can you tell me how to do this DIY project?
im wanting to put my own video signal into one of these and I have taken it apart. now when I try to look up the chips, no exact matches are found for any of them. I feel like I know whats what, but im not sure. I also haven't been able to open the plastic case house the screen to remove it and the speakers. if you could provide any help that would be nice.
yeah have hacked some of these and build in an C64 DTV ... the hard thing was to find small ps2 keyboards that fit in the case. minimum 15 years ago? don't have it anymore.

Woah! How'd you read my mind?! That's exactly what I was gonna do. I just need a RPi and a keyboard.

if its not using a custom made lcd you can usually get a custom driver board and use it as a small monitor.

Took me forever but u can buy a usb to av adapter with software for converting vhs to digital format’ vhs ribbons will go bad over time and deteriorate and like u had a boat load of old family home videos’ the sucky part is u have to sit there and watch the whole thing as it records then hit stop when it’s done etc but in the end so worth it now those memories are mp4 and digital can put on sd card thumb drive etc make a dvd from files etc’ think my vhs to dvd converter was like $13 on eBay this was a few years ago prolly $20 now with everything going up’ but so worth the pay off cause vhs will go bad even just airing unused and those memories r gone for ever something to think about hope it helps bud
@@joshymcdaniel9233 thanks for the information l. I'll definitely look for this adapter. But sadly my VHS player broke I hope I'll find a good one somewhere. But yeah I have some old VHS tapes and the quality of those are really bad hopefully with a new player I can record those old memories.
Our old great scott
wonderful! I have asked quite a few computer technicians if I can use a broken down laptop LCD as a desktop monitor, and their answer have always been "no" though in my mind I knew there must be a way...
+Stephen Chen That is completely different. The answer is actually not so much a "no" as a "not easily, and if you have to ask me it means you probably dont have the skills to do it, so I will politely just say no rather than try to explain it to you".
I will however take some time to explain it, simplified.
The LCD panels in portable DVD players and other integrated devices have multiple components, one of which is a controller. This controller manages the pixel state in the LCD screen itself, which is a fairly intensive task. It decodes the input, works out which pixels need to be changed and writes the new data to the LCD bus.
A laptop panel however doesnt have this controller. The video card in the laptop is responsible for performing this task. What this means is that the LCD itself has nothing to decode the input, or change the state of pixels...Now of course you could build a circuit to do this, however it would be cheaper to just buy a screen already made with the characteristics you wanted. There are some third party products for this task, they are limited to lower color settings than you would get from a computer though..and the resolution isnt that great.
The issue largely comes from the massive data throughput needed to operate a computer display...each pixel has to be told which color and brightness to display...in the old days when you had windows 95 you might remember 16 bit color, etc...Well for us to control a HD display we would need a minimum of 24 bits per pixel. Some math:
24 bits color depth (considered "true color") Note, this mode doesnt have transparency support. 32 bit is minimum for that.
48 bit is the new 4k format, and has millions of shades of every color.
1920 * 1080 = 2073600 pixels
2073600(pixels) * 24 (bits per pixel) = 49766400 bits to show an image on the screen at minimum color depth.
The final piece to this puzzle is the refresh rate. That is how many times per second does the screen update...40 frames a second is considered nice, but 30 fps is totally ok for video playback.
49766400(bits for a frame) * 30 = 1492992000 bits per second to update a standard 1920 * 1080 panel at 30 fps with 24 bit color depth.
1,492,992,000 bits per second = 1492 mbps.
Standard adsl 2+ is around 24 mbps
Standard HDDs read at about 120 Mbps or 916 mbps
So the speed that your computer can read your hard drive data is about half as fast as you would need to run a monitor at minimum...Im not saying its impossible, it isnt...but it would cost a lot, and take a lot of time and effort..and the end result wouldnt be as good as you could get off ebay for 1/100th the cost or less.
So as you can see, it takes pretty powerful processing hardware to run an LCD panel...You would be better off trying to hack the video card. Of course that is extremely hard for a variety of different reasons.
Hope this helps
+Tyson Popynick Pixel clear :) I do know a little about electronics and does pc tweaking trouble shooting in my spare time and I still wish I could revive some of the dead legacy electronics here at home including a broken laptop with an intact LCD hahah. but very well explained I prolly have to keep things practical.
You sir just won my appreciation
I have a few old GPS touchscreens for cars. I would like to see you do a video on using those as maybe a portable gaming device maybe make a portable Playstation or Xbox. Or turn a desktop into a portable machine giving you desktop power with laptop mobility. Also want to learn how to run my PC in my car
How about the original speakers? Did you use them?
0:15 Me.... Fuck Netflix, Blueray disks, and Redbox.
I want my Blockbuster selling plain old DVDs back!
Me. With 2.8 Mbps internet Netflix is very buff. As in it buffers alot.
DVDs are great. On the go you usually don't have enough internet to stream content and only few Notebooks have BlueRay readers.
ohne scheiss.. geiler Typ !! haha, Danke Dir !! ich hätte null Plan gehabt, aber das eröffnet einiges ... nice

"Who use dvds now "
😂 2020 - me 😂
same lol
I save anything with a lcd or led screen. I must have 10 or so old portable dvd players. And about 40 plus digital picture frames.
Awesome Video! I have got a Philips portable dvd player which I would like to mod in the same way. The problem is that I only see a video cable from the main board to the tft board which is labeled RGB (3 wires + ground). Is there a way to input composite video in that case? The main board is a "PET702 DVD BOARD".
One of the greatest thing about av is that it can be used as input/output.
But I have seen many laptops but they have hdmi output no input.
Scott,i have an tablet screen and i want to modify it to a monitor for all uses.
My problems are two,1:How do i get to know if my 9 inch screen is tft or lcd,2:which monitor control unit should i use
I was looking at using the camera from some old phones. NOT too old, say S3 or S4? I should have a Sony with a true 22 MP camera. My question is, Do these send composite signals or do you have to do some digital decoding? All hacks I find here are about removing the IR filter. Thats nice but a hi-rez camera made to fit my 4" telescope. Thanks for your time.
I've got a control board and a 4.5inch LCD salvaged from an old product display, this seems like an excellent way to put it to use, but how would I adapt it to something like an HDMI input?
Wow. Ty. U DA man. Man. U have made a fan out of me. Thank u again
It can't be a cold cathode, because cold cathode is a sort of vacuum tube. This is an EL (ElectroLuminescent) pad.
Still, good video on a simple and fun project.
bravo👏👏👏👏👏. What I was saying is an app you use can also be the details of the Sharp, for example video in
Why not getting rid of the other big board and use the Panel alone. When i looked in the datasheet, i saw RGB in. Could you put an VGA-Signal in? Maybe you could use the Display as a small extra Display. I also just kept the screes with boards from old DVD Players, but its really hard to find datasheets for the Driver ics so here you are very lucky you fine one.
Very interesting videos, thank you for making them. I subscribe after the first video but found this one very interesting. I have an older portable dvd player like the one in your video, and I have a question about it. could a port be added even if I had to mount it outside of the case where a usb flashdrive could be used since it can hold several movies rather then packing several dvds for the kids to watch on road trips.
I tried this with another model but the same chip on the driver board but got a gameboy like screen (green background with black pixels).
Can somebody help me? Thanks in advance
This was way better than that other guy shit asking for help but labelling the video as what you can do with a tablet screen...
You are amazing. Love your videos.
someone in 2018 ? stay creative aaand i wiiiil seee u neeext time 👏
Plz make a video useing the LCD to another projects what else we can make by the lcd
The S-VIDEO port at the beginning might be just a custom-build non-standard 3.5mm connector of this standard en.wikipedia.org/wiki/S-Video , which connector's shape looks like PS/2 mouse connector in it's normal size
Super, soweit bin ich auch gekommen (mit einem anderen Modeel, als LCD Controller ist der T100A), allerdings Frage ich mich ob dein Display auch ohne daß Mainboard funktioniert, bei mir jedenfalls nicht, da wohl Kommandos via I²C gesendet werden....
Nice video ❤❤❤
Can we drive this setup with VGA cable as a pc monitor ?
As you know dvd players have small amplifier.. I want to run my (big) speakers but they lack volume and power.
So I wanna remove the DVD tray completely.. It uses a ribbon cable to a decoder board, can you tell me how to do this DIY project?
im wanting to put my own video signal into one of these and I have taken it apart. now when I try to look up the chips, no exact matches are found for any of them. I feel like I know whats what, but im not sure. I also haven't been able to open the plastic case house the screen to remove it and the speakers. if you could provide any help that would be nice.
Great job! Is there anyway to use an iPad 4th gen LCD as a monitor?????
There is always a way. But it is not simple.
Thanks Bro this was very useful for my project.
yeah have hacked some of these and build in an C64 DTV ... the hard thing was to find small ps2 keyboards that fit in the case.
minimum 15 years ago? don't have it anymore.
if i could make it i would not destroy the case i will take the board and put it in the case
Was würdest du zum basteln eher empfehlen? Den Banana Pi oder den Raspberry Pi?
XperiaArts Ich würde momentan den Raspberry Pi empfehlen.
Hey great scott great video.keep it up.
Hei Scott I have one but a different type how do I get the video pin and ground? Could you explain how you follow the video path to pin
What was the brand or info of the LCD, the final one. i have two just like it but i'm having trouble finding a control board for it or adapter.
Ich hab einen Universum DVD Player.. wenn ich das Video Signal eines C64DTV einspeise ist das Bild schwarz/weiß!! Weißt du woran das liegen könnte?
