Hi,

yesterday i did my first pro sound mod on my classic gameboy but i unfortunately noticed, if i lower the volume to zero, the display turns off and the gameboy crashes. Is that a usual side effect or did i something wrong? i just soldered the post pot pins (as shown here: http://lowgain-audio.com/images/Gameboy … olpot.gif) directly to the cinch jack. My Gameboy has also a backlight installed.

the crash demonstrated here: https://www.youtube.com/watch?v=6itt1l4FQ08

I just soldered a second one... without these crash. It seems i have to check the first one.

It's possible that maybe you shorted something out? Who knows, if you still can't figure it out, I would post close-up images of the board.
