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

[Baspotv]

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.

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:

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

[stj]

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.

[stj]

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

[stj]

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

Thank you so much and sorry for the late respond, I had many problems to solve in the last few weeks
