De-Yellowing DS Lite Screens

[@indy5280]

What probably happens is that the polymers degrade. The digitizer is plastic which happens if it’s hot, or in combination of UV light and Oxygen. There also is plastic in the screens

[@boshi9]

Wouldn't that typically be an irreversible process though? Plus it yellows when the device is not use, i.e. not exposed to a lot of UV and heat.

[@indy5280]

@@boshi9 People have been doing something called a retrobrite. It is with the use of Hydrogenperoxide and UV light it starts a chemical reaction that reverses the yellowing

[@speedlolita]

My Game Boy Micro came a little yellowed. I left it on max brightness for about 3 hours and the yellowing was mostly gone. Glad this was discovered

[@robosoldier11]

same here I was pretty concerned but glad this ideally fixed it.

[@SDogo]

I'm pretty sure the top screen is de-laminating, that's why the black spots looks like they are moving.

[@dgan2304]

Why does that happen? Is it a defective device or just happens with heavy use and old age?

[@PotatoHunts]

Normally the yellowing on Ds lite’s is caused by a single layer inside of the screen, I don’t think the digitizer normally yellows

[@PyromancerRift]

It dont, i am refirbishing DS lites and all the screens were yellow, none of the lenses and digitizers were causing it.

[@The_RetroHero]

Nice! Good to know.

I recently did some experimenting with these, and this solution seem to coincide with my findings: I have 4 subjects, the one that looks most worn out is the the whitest i have, while the one with a broken hinge and basically no wear on the buttons is the worse worse, other 2 follow a similar pattern, i ended up sacrificing the lower screen of said "worst one", because i was under the assumption it was a plastic layer inside the screen that was yellowing, this was false, no layer showed signs of yellowing when put in front of another backlight, therefore, my conclusion is that the blue sub-pixels themselves seem to have gotten weaker over a long period of no use, making a solution like this very plausible.

[@MagnumForce51]

If it's blue sub pixels I wonder if running them on blue screens would be faster then white?

[@Jamesssssssssssssss]

@@MagnumForce51 It was my thought process simply because blue is on the opposite side of yellow on the color wheel.

[@MagnumForce51]

@@Jamesssssssssssssss It's about how the colors mix. Red+Green = yellow. Adding Blue to red and green makes it white if all are at equal intensity. Red + Blue but with less then equal Green = pink. While Green + Blue with little or no Red = a teal blue color. But if Blue is is the one that is less then the other two, the result is yellow which is why I believe it could be an issue with the blue subpixels. ;)

[@joe-un7gq]

@@MagnumForce51 I wonder if you could see that if you put a microscope (maybe one of those handheld ones) on the screen and comparing a yellowed screen to a non-yellowed screen

2:07 You should also try peeling the LCD layers off, it peels off like an onion. I peeled off mine and replaced the polarizer (beats paying $20 aftermarket screen), it's not glued in unlike those DMG gameboy. Apparently, the top polarizer was the only damaged part (yellow+circular shape) and there was also mold in between one of the clear ones. Cut the polarizer to size and clean with water, dry it and it was good as new! WARNING: DON'T CLEAN WITH ISOPROPYL ALCOHOL, it will damage the plastic. Just use WATER. I don't see many youtube videos teaching that so you could make a video out of it.

[@PotatoHunts]

Where did you get the Polarizer?

[@jackipiegg]

@@PotatoHunts Any lcd polarizer can work. Just need to cut to size.

[@FlowerPower-k9s]

YOU CAN REPLACE THE POLARIZER???? I thought about doing this but didn't find any resources. I have a bunch of DS screens that have these very thin and perfectly straight horizontal lines. I think its the polarizer. Do you have any resources? Is the polarizer inside the LCD or outside at the very first layer?

[@thebestSteven]

Got some DS line handhelds to clean/repair/mod, and had a nice condition ds lite with busted bottom screen, dirty nasty ds lite with good bottom screen. Awesome, best case scenario because top screen is harder to replace. I'll take screen from dirty ds put in clean ds. As I open it, it was a white one, the first thing I though is, this came from a smoker's home. Sure enough, I get it back together and wouldn't you know the screen works but is yellow. I believe the UV lights will help speed this up and not burn up your ds.

[@brandons8661]

I had the same conclusion after buying used DS's and seeing them get whiter over time. I was thinking I was hallucinating till i saw this video.

[@henriquearroxelas1510]

There should be some homebrew somewhere that just keeps a white screen 😂

[@RumyJCR]

or play a pokemon game and take the cartridge out, boom. white screens on both screens

[@AlexTheSuperNintendoGamer]

Very cool video, keep up the good work, my friend.

[@adultmoshifan87]

Hope it’s possible to de-blue a New Nintendo 3DS screen! If not, any professional repair folk in the South East of England able to replace the screen? I don’t mind if the replacement screen isn’t IPS, I only care about whether or not the colors display correctly.

[@Cj_Plays_Everything]

If it’s the bottom screen I would just repair it myself if I was you, if it’s in the top prob need to send it in.

[@Anthestudios]

I have the idea especially screens from Japan are quite yellow. Might take the plunge!

[@abdullahrex4769]

11 Y/O back in the day smoked cigarettes ,thats crazy!? Ik nice joke, cracked me at a sad moment.. Thanks

[@JoshRBuchanan52]

Super interesting video.

[@crosswalkX]

You should replace the top DS lite screen. To Jake64, I noticed the top DS lite screen in your video is glitching. Can you do a youtube video on replacing the top DS lite screen, because it's broken and glitchy. Let me know if you're interested in replacing the broken screen, I'm fixing my sister's DS lite screen. And keep in mind you will need triwing screwdriver and 4 way screwdriver and soldering iron for the speaker wires to top screen ribbon cable.

[@apadia8447]

nice. gonna try that.

[@basiceric88]

Has anyone tried this on a dsi xl? Mine was in perfect condition and then I turned it on after not using it for 1-2 years and the screens were all of a sudden extremely yellow

[@henriquearroxelas1510]

Nice!

[@Wesellyourentthriftshop]

The same thing happens to the PSP

[@Julio-591]

Dead pixels top screen 😊

[@Tomiply]

Yeah, as a monitor calibrator, I would never recommend running a screen on its max brightness for weeks. That's really bad. If someone has a yellow screen, I do NOT recommend doing this whatsoever.

[@Aeduo]

These screens aren't drawing a ton of current or producing a whole lot of heat. That's probably why it took a month and still didn't do a whole lot. Whatever small amount of heat (or light?) energy it was emitting was probably enough to cause the reaction. I believe the backlight had gone to LED by this point too? But yeah something like some crazy high power modern LCD beaming out 1000 nits for weeks on end is probably not good for the backlight, and whatever else might be sensitive to the heat. :p

[@JakeSimmons64]

Do you mind explaining why?

[@henriquearroxelas1510]

There should be some homebrew somewhere that just keeps a white screen 😂

[@Anthestudios]

Shouldn't be too difficult...? I'll have to check that out

[@Aeduo]

Probably just leave it on the health & safety screen, or if there's an image viewer that can span both screens, loading up a 256x384 image of all white would do.

[@MagnumForce51]

No need. Just try and boot a retail game with hbmenu... Easy White Screen simulator. :P
