I was doing a "simple" repair but the board was already very worn and dirty and all 5 five pads for wheel came out with the pin volumen wheel, so , how can I connect this 5 points with other points on the board?
Thanks for the awesome tutorials. We have a load of gba sp mobo,s with charging faults if you ever fancy running through all the possible causes that would be amazing.Thankyou
Can you explain where each pad of the volume wheel goes to I accidentally pulled one up and I can’t seem to trace it on a working board. My current issue is the volume doesn’t go all the way down like I’ll still hear it if the wheel is all the way down
What are you using to power the gameboy? Is there a budget friendly option? Also can I use a multimeter in place of the oscilloscope? Or do I need one for this? Is so, what is a budget friendly option?
@@RetroSix hello retrosix good afternoon, maybe it would be too much trouble to share the diagram of the Gameboy consoles that you have, I think it will be very useful for us, your followers and the technicians, thanks

Hello there! First of all, awesome video mate. This is the most high-quality and thorough gba audio system explanation I've found. I would like to ask you. I switched the volume wheel off my GBA and now the volume doesn't turn fully off, with the volume wheel all the way down you can still hear the sound a little. Do you know what could be the problem?
@@RetroSix I removed the wheel completely and I can still hear that quiet sound. Testing voltage on pin 10 I can see I have 0.80 volts, where in your working tests you get around 0.40-0.50 volts. Do you have any idea what could be causing this? :/
Hello, sorry for my bad English. I wonder if you could help me, I get a game boy advance recently but well I got the same problem, it have no sound at all, so I want to fix it but I don't have the tools like the oscilloscope, so I hear you say you could solder a cable directly, could you tell me where I should solder it, I appreciate your help.
Hello @RetroSix, your video and wiki are very useful to me, I try to fix a GBA with no sound, I follow the trace and went to c45 point, I get 3V there, if I flip the board and take the same point I got 0.6V, this is the same voltage I get into pin 10,14 and 16 in the Amp and at the volume wheel too, did I need to short like you do or not. I didn't understand why I didn't get same voltage in front and back of the board for the same point. Thanks in advance
If you have different voltage from top to bottom your via is damaged and you should run a wire between top and bottom to rejoin the connection. However C45 is headphone out left and it should be less than 1V so I think you are measuring wrong place perhaps. Join our discord for more assistance discord.gg/retrosix

When you say "lets take a look" I hear "lets take a LUKE". Love the videoes, thanks for your contributions to the community!
Haha. Now I need to try and not think that every time I say it

Certainly will given time

Me too
Great vid!!
This is really cool! How do you get the camera to get so close up?
Microscope

Bench power and oscilloscopes here. retrosix.co.uk/Diagnostics-&-Bench-c141184571. You would need oscilloscope as multimeter won't do
Hi, I had an issue with very soft audio. Where do you recommend that I should start looking into ?
Trim and resolder speaker wires, check voltage on volume wheel middle pin should be battery voltage at full volume so about 3V
@@RetroSix Thank You, now I'll just have to wait for the multimeter to arrive.

Awesome explanation and pacing - appreciate it!
Thanks
Obrigado pelo vídeo, voce pode disponibilizar os arquivos e fotos da placa que você usa no video?
Darn... those vias are problematic as hell... Thanks for the informative video!
So I have a problem with audio. I get audio to one of my headphones and that's all. No external audio

That's third party wheel that's not the same resistance as original so never turns off
@@RetroSix Yes that may be the issue there. Do you know where I could get a good third party replacement for the volume wheel?
Currently there are none on the market so only from donors

Jump on discord.gg/RetroSix will be quicker to diagnose, and send photos of that area of board
