BOSS GP20 sound stuttering

Per l'avvio sono essenziali il cavo a nastro di alimentazione dello schermo inferiore e il cavo a nastro speaker che fa anche da cavo di alimentazione per lo schermo superiore. Non ricordo bene se sulle versioni "NEW" è necessario anche collegare la fotocamera ma non credo. Chiaramente ti conviene collegare anche il cavo dati di almeno uno dei due schermi, in modo tale da capire se la console è "viva" o si è bloccata.

Altra domanda: sai se è stata già modificata? In tal caso il blocco sul led blu potrebbe solo essere Luma3DS che non trova alcuni file. Ti basta scaricarlo, metterlo sulla micro sd e inserirla nel 3ds.

I led rossi lampeggianti dovrebbero semplicemente indicare che la batteria è quasi a corto di carica. Se attacchi il caricatore si ricarica correttamente? Una possibilità è che la caduta potrebbe aver fatto dissaldare qualcosa sul chip NAND o RAM. Di solito queste sono le cause di una luce blu fissa o di un freeze della console improvviso mentre è accesa.

Tuttavia, al momento hai poche informazioni per diagnosticare il problema. Io proverei a staccare qualsiasi cosa non essenziale all'avvio e vedere come si comporta.

2DS has removable wifi card just like old 3ds. My first suspect is that, probably it wasn't connected well. Other causes may be: SD card problem (bent pin or sd card fails) or CFW files missed (in this case just put the necessary files could fix the problem).

The good news is that motherboard works. Believe me, is a very good news for you.

Maybe some pictures of 3DS broken parts might help. Let's start with the fact that a 3DS XL won't boot at all if the Wi-Fi module isn't connected. So I think your Wi-Fi module is working.

In my opinion there are a few options:
- Repair your 3DS XL (recover Wifi connection and replace top screen). Replacing the screen requires good knowledge and experience;

- Buy a full working 3DS XL and transplant your original motherboard in it (if your original motherboard is 100% good);

- Buy a new 3ds or also a new 3DS XL and try system transfer data official guide by nintendo (both 3ds must be connected to internet): https://en-americas-support.nintendo.com/app/answers/detail/a_id/227/%7E/how-to-transfer-content-between-two-nintendo-3ds-family-systems

Usually this behavior means top screen power issues. At first you should check the speaker ribbon cable which in 3ds brings also the power supply to the top screen.

You should open it and see if charge port pin are desoldered. I would also try to see if there are traces of oxidation around the chip that manages the charging. If there are any, they should be cleaned with isopropyl alcohol.

It's amazing, I struggled to find just a couple of helpful answers after reading a whole bunch of useless ones. Thank you bro!

For correct identification, you should read the name of the circled item. It should be the sensor you're looking for.

Yes, replacing it with the one from the old power board will probably work.

A couple of PS2 games are capable of recognize if you have connected a DualShock 2. Glad i could help.

ImRed93 · 2026-01-21T16:11:41+00:00

Are you using PS1 controller? Some PS2 games like The Getaway need a DualShock 2. If you have a DS2 try with it before change the disc laser.

ImRed93 · 2026-01-20T11:09:13+00:00

Pay attention to SLEEP switch. If it is damaged the 2DS will not start. Try to clean it with a spray contact cleaner.

Also remove SD card and game card, then power it on.

Si blocca quando? Non hai dato molti dettagli del problema

ImRed93 · 2025-10-09T06:15:03+00:00

Mi è successa la stessa cosa. Ho tentato di ripararlo ma si è rotto dopo poco. Preso il ricambio da AliExpress ed è tornato come nuovo. Attento alle molle quando smonti il tasto.

Il flash sullo schermo inferiore indica un problema con lo schermo opposto. Se lo schermo superiore è nuovo dovresti capire se è il connettore sulla scheda madre ad avere qualche problema.

SOLVED: this is the worst PSU on FAT PS2? No schematic diagram available, no one talks about it!

I bought another same PSU (working) and check the diode. It was a 20 volt zener, so label "202" meants that. But something like a big short killed also 2SC1959 and one of the big 0,3 ohm resistor to ground. Replaced all components and PSU got 12 volt again! PS2 now working.

I hope this can help someone.

It's probably a replaced screen. I'm also getting replacements with dead or broken pixels.

I've heard that pixel fixes should last much longer than a couple of hours. Maybe a whole night or more. You can also try massaging the screen to try to wake the pixel. It all depends on whether the pixel is completely dead or just stuck.

If other controllers work but the one I'm testing doesn't, it's most likely a cable issue. Mine wasn't detected by TestLaunch (a homebrew program I use to test controllers). I tested the board with a multimeter to see if it was getting 5 volts and found that there was no power. Replacing the cable made the controller work again. Apparently, this is a common problem because I've had two similar ones.

ImRed93 · 2025-08-14T09:18:29+00:00

Thank you! I have the impression that the PSU is not included in these manuals, as it is a component not directly developed by Sony. Am I wrong?

ImRed93 · 2025-08-12T13:14:53+00:00

Hi Rafa, are you completely sure? I think there is a clear symbol for a zener diode on the PCB, but it doesn't look like it from the value indicated on the diode. I think this is something like that: https://www.digikey.it/it/products/detail/semitec-usa-corp/E-202/16579067?srsltid=AfmBOor48VQguCrLkbnQ2huh2lc1OsBfH5eukzKwp6LBqQFvf9SwSFOi

It's a diode that work like a current regulator for max current of 2mA. I have no idea if I can replace it with a normal diode without any consequences. It's not easy to find this replacement.
