- How I added RGB inputs into an average consumer TV to make an arcade quality CRT monitor. Not a very easy mod, but the more DIY-how-to's are out on the web the better your experience might be. Results are very impressive, but at the cost of difficulty.
A soldering iron and multimeter are all you need to do this, however a general understanding of what's going on inside a CRT TV is a must. Read those datasheets carefully.
Buy my book: amzn.to/2W5r6Kj - วิทยาศาสตร์และเทคโนโลยี
Not only did you greatly improve the image quality, you also now have a monitor to connect arcade boards to. :)
That's the plan!
You can open any TV and take note of the ICs inside then look up data sheet for the chips. Service guides aren’t always available
Wow, seriously, you did your homework. Outstanding presentation!
thank you!
Like most of us, I lusted for a PVM or BVM. Still don't have one, but I think i can move on knowing this mod actually works. I do have a 27" Sony Trinitron tube TV and well, now I just might mod that. Modding this 13" TV was was increasingly difficult because this TV was
1) small, making the PCB cramped, and;
2) newer making the PCB full of surface mount crap and also lacking a service manual.
Fun fact. I paid $30 for this beauty NEW when I was working at K-mart in ~2005. I worked in the electronics dept. It was a wild ride.
You did this one the hard way, which is great for more obscure set like yours, I have done a few that way too, using photoshop to trace the PCB, but RGB modding has never been easier as there is a lot more info available these days, with your specific Sony model chances are a mod (if doable) has already been documented. shmups forum and CRT collective on fb have a lot of set specific RGB mod info. Also look out for JVC D-series, they are amazing and great mod candidates as well
Oh man I just forked out for some from Japan, one is a more recent 14 inch 100v-240v so I won’t need a step down converter.. the other is 1992 14 inch model and needs a step down (240v here in aus) and then a small one simply because it was $15 ...this was all good until I got the postage quotes !! Still no more than I’d have paid for them here .... they better have language select in the OSD!!
@@vajskidsconsoles2005 how much was shipping $250? never see any crts where I am in QLD
@@vajskidsconsoles2005 also noticed your ebay store, you're a beast
@@Vvewa it's slowly dying off. eBay are removing a lot of premod consoles. will move else where. Etsy closed my store while my first sale was processing. just a PlayStation with an Xstation and my psxtal dual region and IGR. I am from sunshine coast Queensland :) living in Melbourne ATM
Very useful video. Thanks for the detailed descriptions and diagrams!
Glad it was helpful!
Nice work!
that tv is pretty nice it reminds me of the rca tv i had they have a similar style chassis and even the same looking settings menu. lots of good memories on that
this tv has seen 113 stars of Super Mario 64.
Thanks dude, great mod
Glad you like it
Great video!
Thank you for making a video about this hack !
No problem!
Awesome video. It would've been cool to see how the dithering on the waterfall in Green Hill Zone compares between composite and RGB on this TV. The waterfall is said to actually look better in composite as the dithering was designed to take advantage of the poorer quality of composite or RF.
Great suggestion
Nice, try to do this mod on Sony Trinitron set, the results of this mod will be much better. And also you can use scart female connector insted BNC.
Now I'm google'ing if my Panasonic CT-20SL15 as already been documented to RGB mod. It has component so currently using scart to component box which has its own psu from ebay

Not all tv have manual for model tv because sometime one chasiss serve a few tv.
Try to search the chasiss no.
I find itt,metz 13 inch and philips21 inch same chasiss and different model
That chassis looks very similar to the ones in early 2000's small RCA and GE sets (the ones made after they did away with the dreaded Tuner-on-board design) Perhaps the manuals may be cross compatible to some extent as well.
what is the "Tuner-on-board design"?
good job
kick ass work!!!
thank you
Sick MOD
Awesome!
I’ve had better luck using the RGB out, or tracing them with a meter. I have done 3 successful ones in a row now. I did a sharp the other day, pinouts showed OSD R/G/B and blanking. I could only get the RGB through the OSD text using these pins. Blanking just killed the screen. I moved RGB across to the RGB outputs (which you have as Pin 19/20/21) and voila , RGB with sync on the channel I tapped the composite on for sync ... only need to switch blanking when using composite over sync... otherwise with C sync it worked without blanking. I do prefer to switch blanking even on C sync as it does change the colour tones VERY slightly ... Each TV has being slightly different. The Hitachi with Phillips main chip I needed to trace RGB tracks until I was basically sending the signals direct into the neck board. Same thing where blanking was only needed for composite over sync. And also a trinitron flat screen. I have an LG and Samsung and older model small trinitron to do eventually
Interesting comment VajSkids. I have a Sharp portable here that I plan to adapt and you mention pins 19/20/21 I am assuming your chassis uses the TDA 8362 which has the video out on the same pins?
These mods are insanely hard, i also attempted it some years ago and i gave up halfway through when i had to make my own amplifier circuits and what not.
It would be awesome if you could RGB mod some popular TV models like the Wega/Trinitron, etc, they all probably share a lot of common parts like the Jungle ICs, then it would be way easier to get one of these models and just follow your instructions.
It is hard but luckily, we have forum and reddit guys that are passionate.
Stabers this guy from Reddit gave me very specific instructions on where to cut and what parts i need.
Even drew me sketches himself
It even led me to learn the basics of resistors and capacitors.
Ryan great video!. I have the same idea as you. I am building a Neo Geo MVS sort of clone but with a 32" Sony Trinitron KV 32S22, my mother donate it. I have all the schematics, all the rgb lines that go into the jungle chip identified. The thing is that I want to put an original 2 slot mvs board inside of it.. so I might need a supergun right? To output either RGB component or Scart connection , I see those superguns have controller (gamepad type) inputs on the front, like for Sega Saturn and such which I don't need and they block the harness entry for arcade buttons wiring. Do you know of any dedicated video procesing board for MVS that leaves the arcade harness connections free and that will let me hook this thing to my Trinitron once I mod it?. Also what route do you recommend component or Scart
A supergun will get you off the ground faster, but it's not necessary. The MVS 2-slot outputs RBG, so i'd stick to this signal type. You really need a power supply for the MVS board. A super gun does this, or a modified ATX psu will do it too; you need 5v 12V, and -12V (for some amps). A JAMMA harness will break out everything you need from here.
Hi. Its switchable for any CRT TV?
My tv is a 29FS4RLG TV, I am in doubt if the input of pin 82 blkin is where I put the 5v ???
same for me, with a LG 14FK3RB-L2, I can't see any pin with a BLK or blank tag, I dunno if i should inject 5v over pin 11 that said RGB VSS_9V or pin 44 FPB
I know that these RGB signals from a home console are on the 31kHz side of the Force. But would a CRT RGB modded TV accept a 15hKz RGB signal as easy as a 31/47kHz?
it would not. you would want to look for a 'multisync' TV / monitor
I'll try to make it quick. I want to add component jacks to a Sharp 25R-S100 to hook up a og Xbox or PS 2 to replicate a primal rage arcade. What ohm resistors should I use? A walkthrough digram will help alot. thanks.
i dont know
Love it.Which CAD program did you use?
inkscape
Excelente
I have the very last gen LG's Tube TV (lg 14sr1ab). I love it to death but one bad thing is that it only accepts composite input. Is there any way to have it accept higher resolution video signals? I believe it was capable of doing SD resolution.
if it has on screen display, it is a candidate for this modification.
@@RetroBuiltGames A TV without an OSD would be like those really old CRT that can only be calibrated with potentiometers outside the TV? I have a Sanyo CRT from the 90s (Composite and RF only) that sorta has an OCD but is very basic, just green text and bars over the screen.
Im in UK and I want to do something different, I want to convert a RGB scart socket into a Component input, one of my tvs may even be ready for it as it was a 2006 model which has the cutouts already on the shell at back its likely they just never wired it into to the circuitboard, its so I can connect a PC to the tv and all in one retro setup, i.e play emulators, watch stuff off my NAS as I prefer it to a LCD tv.
I'm so jealous it comes like that out of the box.
What CAD program do you recommend for tracing circuits like in the video?
inkscape (its a vector drawing program)
I have a TV (CRT monitor ) with 'AV component IN' with R (Pr) Blue (Pb) and Green (y) , may I connect my MVS directly to those (TV CRT Panasonic 29FJ30LA)
No. RGB and Component (YPbPr) are are encoded differently. You need essentially a box (common piece of kit) that says it converts these.
Successfully did this to a Trinitron. Unfortunately, the TV's chassis had a gaping hole in it to begin with, the CRT is beginning to break off from the cabinet, and the whole thing will probably shatter like an egg if moved again.
What model Trinitron?
hi.. i have a lg flatron tv and it has component input but it only says (480i) why? no component cable is for 480p
your TV might only support interlaced mode for component inputs.
My Jungle chip (AN5302K) has inputs for Horiz and Vert sync. Could I wire those to BNC also if all lines are on something like a 4PDT switch? Would I even need to put the blank on a switch that way?
what signal are you routing in that has separate inputs for H and V sync?
@@RetroBuiltGames VGA 😬
@@Ashene64vga would not work since that is 31khz while analog television RGB is 15khz
I think there were some 31khz TVs (mainly HD CRTs afaik) but most only accept 15khz
There are tricks you can do to make your computer's video card output 15khz though.
Alternatively you can get something like a GBScontrol which can convert VGA to 15khz.
I was wondering if you could help me with a project of mine? I’m trying to rgb mod a tv from the late 90´s. I really need help on this mod
ask your questions here, the community might be able to help.
Brilliant work. Alas I laugh at you in *scart*
haha thank you
Really cool. Wanna do my Panasonic 27" next? haha
after i do my 27" trintion... which intimidates me significantly.
@@RetroBuiltGames I would love to see the results.
You used composite IN on the TV to feed sync signal ?
correct. Sync is carried on composite, so that connection is still needed for RGB timing.
@@RetroBuiltGames Thanks ! 😀. Still i dont know...Opening a CRT is kinda scary. High voltage 😱
don't be scared, just respectful of those votages!
i wish more people were into consumer crts. Those PVM/BVM are way too tiny. i dont understand how so many people use super tiny screens
a lot of the appeal of smaller screens is to play on a desk, a lot of people struggle with space, or justifying bringing massive old tvs inside the house to their partners.
@@djcalle1975 anyone with a PVM usually has 3 of them lol.
if you hire someone to mod for you, what would be the cost?
$$$ out of $$$$ dollar signs.
it's fun doing it yourself~
Can we make it component video?
it´s basically the same as RGB
@@shiroumxm2052 the connectors and signal are different.
And for me, for instance, who had the luck of picking up a great component cable for my PS2 for cheap, don't want to buy an RGB cable :/
@@shocknawe I meant they look the same .
@@shocknawethe PS2 can output RGB over component cables because the pins used to output RGB and component is the same.
Don't put any disc on startup and under the clock settings you can change the output type from ypbpr to RGB
@@shiroumxm2052no it's a completely different video signal incompatible with each other. You have to convert it first.
Its chip methods.
I do two modification
And results low quality dark picture.
Not good for pandora or 60 in 1
Some arcade games nornal
And others bad.
Not good for all console.
In my opinion.
In usa try to buy rgb or arcade monitor
In Europe we have luck with scart tv
Just need good sony kv with remote control .
Or jvc toshiba etc.
Why would anyone want to do this if the color is darker than composite video?
for clarity/sharpness/color accuracy
@@RetroBuiltGames If that's the case, then I guess it just looks darker on video, right?
indeed
Hi, how I convert vga sígnal to rgb ?
I live in the UK, why did I watch this entire video?
to understand why Americans are always complaining.
Could somebody help me to find the BLK pin on LG 14FK3RB-L2 ?
has an all in one chip that doesn't have any rgb input
100!
4:00 you mean SPDT
indeed! thanks
This is quite confusing to me why American television sets don't have a scart connection !?
was one of those cheap + convenient choices made at the time. Like microwave meals, the USA does it fast and cheap.
@@RetroBuiltGames very cheap
Because composite video had already become a standard before scart
Scart only became popular in europe because govt agencies forced manufacturers to use it, kinda similar to how they forced apple to use type C
Most of the world just kept on using composite video until component/ypbpr became a thing.
@@tristan6509 I live in Algeria North Africa and over here even the crappiest sets came with RGB scart as standard and it continued all the way to LED TVs around 2013/2015
There is easier solution - being European
ha
If it's difficult to find the pin outs then give a LINK TO THEM.
sure
