    Nintendo Gamecube missing component DOL-CPU(P) - 01 (Side A)

    So today I was checking on a GC board that I got from a friend and he told me the GC would get an error and doesnt want to read games after a couple of hours gaming on it. So I suspected it to be some bad solderconnection or an capacitor, when checking the solder connections of various components one of them was so loose that it flew off. I think the component right next to it is the same. The board says it's DA15 and I've never heard of that designation. The Text on the component says A1, and this also doesnt help me out. Maybe one of you guys knows what part that is so I can order it instead of buying a broken board and stealing it from that one.

    Well, you can measure the resistance between 1, 2, 3 pins with a multimeter and check that these are diode assemblies or digital transistor assemblies, especially since they are designated Dxxx on the board.

      pure coincidence, i just got a gamecube to strip down for a good clean and fitting a modchip.
      i'll see if i can identify the part at the weekend.
      i think the problem is unrelated though, the dvd drive may have issues but the area in your pictures is i think related to video output - i'll find out.
      your friend should play games from an SD card btw.

        Thank you, I dont think so either, i guess its the capacitors, now I am on my way to order a new set for the GC. I don’t have any other idea what could cause the issue except for the disc drive itself.

          i wouldnt try to fix the dvd,
          just fit the €4 modchip and get a €2 micro-sd adapter from aliexpress.
          this is the thing you need with the modchip to get it going:
          https://github.com/emukidid/swiss-gc/releases

          the modchip redirects reads from the dvd to the sdcard,
          swiss is your boot-menu & ISO loader

            He wants it to be fixed without the modchip, he's a videogame collector and wants it to be like original, he already has almost every game on dvd, so for this device I only need the capacitors and the part that is missing, were you abled to figure out what this part is/does? And btw thanks for your help already

              not yet, need a couple more days.
              i had to spend half the day cleaning it and finding a new fan.
              also it has a lithium battery that will be dead by now.
              it's not rechargeable, it's just a cr2032

              your friend better understand that the lasers do wear out if he uses it a lot.

                The marking on your missing component is not A1, but A2, and it looks like a -1SS309 diode assembly.

                  well mine has different markings.
                  and the 4 arent the same, it's 2 pairs of possibly complimentary parts
                  the missing one is "M5C"
                  the one next to it is "M5B"
                  they are going to the internal serial port used for stuff plugged into the base.
                  probably buffers or line-drivers - i'll try to id those numbers

                    pins 1 and 3 go to the serial port,
                    pin2 goes to ground - but on the complementary part it goes to vcc
                    pin4 goes to the main chip and the serial port.
                    pin5 is not used

                        Are you sure that the other component is not A1 marked, bc right next to it there is one component marked A1 and the other one is marked A2

                          The A1 marking is hard to see; if A1 is there, then this is assembly 1SS308.
                          A1=1SS308
                          A2=1SS309

                          If 2 pin is connected like the third assembly, also with 2 pin, then this is A1.​

                                Just checked, you were right tysm you saved my Gamecube! Do you know by any chance where I can get a cheap laser for the GC?

                                  Nintendo Switch lite shuts down after nintendo log and replaced M96T36o
                                  by fab13
                                  Hello everyone

                                  After checking the defective USB-C port and close to a short circuit on the M96T36 chip (8ohm) I have changed both components.
                                  I specify that there is no other short circuit or heating component(Vu thermal camera)

                                  First, the problem arises: Error 2101-0001 after the start-up screen ("Nintendo" logo), poor soldering.

                                  Secondly, I install a new M96T36 and the problem I have is a brief display of the "Nintendo" logo (no short circuit, no sure charge chip, no sure charge port, no sure charge management chip percentage)....

                                  Xbox Series X - crashing to dashboard shortly after launching games
                                  by survivalbloke
                                  Hey all! I've got a XBOX Series X which came in with the complaint of games crashing to the dashboard after launch. I've tested a few games so far. Red Dead Redemption I observed will load up fine and sit on the menu no problem, but once I actually load into the world, it will not complete the load-in, and crash, stating something about an error must be sent to Rockstar, etc.. Truck simulator seemed to work fine. Minecraft loaded up and zoned into a world, but within a few seconds, it too, crashed to the dashboard. Where are the logs stored? What should I check?​

                                  First, before anyone bothers with the usual "your PAL TV doesn't support NTSC" or vice versa...

                                  This is a regular Australian market SCPH-7502 PAL console, with a modchip, running on a 2003-era PAL TV (LG Flatron RT-21FA31 CRT) and several LCDs, all of which are dual PAL/NTSC and have no issues whatsoever displaying either signal.

                                  It is not a TV or cable issue (I have four PS1 composite cables which work flawlessly with the other three PS1s and two PS2s I have lying around). FWIW, PAL PS2s output NTSC in 60Hz mode, despite the games saying it's "PAL60"...

                                  Gamecube DOL-001 Cap Values/Original Cap Models
                                  by Alexander Gutsch
                                  Hey all!

                                  I need some help identifying the original model of the caps you could see on the pictures below. These all are from a Gamecube and should be replaced as a precaution/repair of the disc drive not reading discs. I know the voltages and capacities are easy to get from most of them, but since I do want to get some high quality replacement parts, I need the ESR or ripple current too to find some equivalent replacements.
                                  I also added a picture of an Excel sheet I made with the designators and the diameters of the caps.
                                  Thanks in advance!...

                                  Nintendo Switch Oled - Joy con charging
                                  by tommy97
                                  Hi everyone,

                                  I'm having an issue with a Nintendo Switch OLED that suffered liquid damage. After a full cleanup and replacing the Joy-Con rails and joysticks, everything was working fine for about a week. However, now the Joy-Cons won't charge or connect again.

                                  I tested with a second set of Joy-Cons, and the issue persists. Measuring the voltage on the connector shows 3.7V instead of 5V, which I believe should be the correct value.

                                  Any insights or suggestions on what could be causing this?
