Hello,
Recently I got a gameboy Dmg.The screen had lines but I managed to fix that.The volume pot was battery corroded,so the pcb pins of it.The question is,what the first left pin is about?I tried to find where it goes but it is connected only on an empty pcb spot(no copper)I am uploading and a photo(the red hole it that).
Thanks in advance.
That pin appears to be connected to the ground plane on the top side of the PCB (bottom pin of VR1 in pic): https://imgur.com/6Pzp8m5
Nice,thank you! But how it was possible to be connected on the back side of the pcb?Copper was coming from up to down?Should I apply solder on the top side?
Could be that a via connects a solder joint on the bottom to the ground plane on the top, and the alkaline may have damaged the via. Should probably make sure with a schematic around VR1.
I'll try this tomorrow,thank you.
Just bought a volume wheel replacement.The problem is,like most pots I found hadn't the correct thickness.
Does somebody know what's the model of the correct pot?Is this product correct?http://retrogamelab.com/index.php?route=produ … &product_id=210 or
