gameboy repair 

removed my first burned polarizer today, from a game boy pocket lcd. it was less difficult than i thought it would be. (tedious but not difficult.) pics show what it looked like beforehand, the middle of the process, and after the polarizer was removed completely (including all the adhesive). i don't have new polarizer film yet, but my sunglasses are polarized, so i used them to check to see if the screen still works (it does!)

i removed the polarizer by carefully lifting it with an exacto knife and peeling away... and then just scrubbing it with isopropyl alcohol and a q-tip for like 45 mins. (i used the exacto knife a few more times, very carefully, to lift some stubborn bits.) the eventual goal here is to install a backlight mod. i know they sell fancy ips lcds for the pocket now but honestly i kinda love the look of the lcd on the pocket

still waiting on my polarizing film and i do wonder at this point how many people have walked past my office wondering why i'm wearing sunglasses and playing gameboy, like some magazine ad from the 90s

gameboy/electronics repair 

another first for me: I resoldered a surface-mount chip in this old flash cart of mine for the GBA. I opened the cart up and found that the SRAM chip (in the upper right corner) had separated from its solder pads somehow—one side was completely loose, and a bunch of pins on that side were bent. I used fine tweezers to bend the pins back, then soldered it back in place (with the help of a lot of chipquick flux). it's not pretty but it does work!

the only problem is that the company that made this flash cart no longer exists, and the software to flash it only runs on Windows XP (if you can even track down a copy). so I'm stuck with the games I flashed on there back in like 2012. fortunately these games are bangers: Metroid Fusion, Klonoa, and Mario & Luigi Superstar Saga

gameboy repair setback! 

boo i ruined this one when i was desoldering the ribbon so i could get to the back light (the front half of the ribbon is very delicate and it's easy to accidentally rip the connectors right off of it, and no way to fix because the connectors lead straight into the tiny tiny matrix controller chip). oh well! now i have an extra gameboy pocket motherboard for some future mod...

gameboy repair success! 

i finished (mostly) this backlit gameboy pocket build! i ended up using another gbp screen i had for the backlight mod. the bivert chip i bought was a dud, i think, but the backlit display looks fine without it imo. this model of the gameboy pocket didn't include a power led, but the aftermarket lens i bought has an opening for one, so i ended up rigging the most homemade power led mod imaginable (just soldered a through-hole led and resistor between vcc and ground)

just finished this custom DMG with an aftermarket IPS LCD, shell and buttons! I love how it came out but it was a surprisingly tough build. I accidentally zapped the original motherboard I was going to use (the DMG's design makes it too easy to send -30v straight to the CPU) and killed the first fancy LCD I tried to install (which the vendor kindly replaced). and THEN I discovered the speaker didn't work, so I had to reopen to diagnose. but it's all fixed now and works great!

the dmg has this reputation for being indestructible, but in my (small) experience, repairing and modding them is like a high wire act. there are no fuses, the dc voltage circuit is unregulated, the ribbon cable connecting the screen pcb to the motherboard is just held in with friction. (that cable has the line for the B and Left buttons right next to the LCD negative bias, so if you don't insert it juuuust right, you'll short the contacts and fry your CPU like I did)

@aparrish
i prefer it too. my favorite is the og lcd with a bivert mod and rgb backlighting. definitely think about the bivert mod!

@aparrish combined with your cw, I interpreted "polarizing film" to mean you were making an explosive documentary about your controversial, cutting-edge gameboy repair techniques

gameboy repair, pol mention 

@valrus next up on fox news, watch this controversial footage of a bespectacled liberal new york city college professor playing video games on the job

gameboy/electronics repair 

@aparrish wow, i don't think i've seen one of those before. what vendor is that? you might still be able to flash it with a GBxCart RW. have you checked this list? https://flashcartdb.com/index.php/Main_Page

@Ludonaut this is the URL on the cart (from the most recent wayback snapshot that works) web.archive.org/web/2009060503

I tried flashing it with my gbxcart rw last night! the software doesn't detect it, and using the "generic" setting didn't work 😔

gameboy/electronics repair 

@aparrish whaddya mean it's not pretty?? I shall insistently disagree

gameboy repair success! 

@aparrish now THAT is one sweet Gameboy! I never remember those having a blacklight.... Memories of playing under a lamp or the sun

gameboy custom build 

@aparrish nice! it looks really good. i have so many of these in pieces that i should refurb

gameboy custom build 

@aparrish
yeah, gameboy color is where it's at. gba too, but I feel like it's harder to make those as cute.

the one thing that's nice about the dmg is that it's big compared to the others? that ribbon cable though... 😣

gameboy custom build 

@aparrish Nice build. I once ruined th LCD while removing the polariser. From that moment on I used the IPS v5 kits. Those are plug and play and have a much better image. And with two wires you can get AV out.

@aparrish it’s beautiful !!

@aparrish
wow, love it!! 😍 I should get back into gameboy modding, it's so fun!

gameboy custom build 

@aparrish wow! I have fond memories playing the second dream land. -32 volts! Woah, does the screen need that or something?

gameboy custom build 

@JamesAkers yeah it's the negative bias for the stock lcd. i don't think the aftermarket ips even uses it—in the future when i do ips mods i might just desolder that line so i don't have to worry as much!

@aparrish I like the colours 👌
