Turbo Duo with only one channel sound in CD games
« on: August 11, 2025, 09:40:11 PM »
Hi, I have a Turbo Duo with a slight problem. I recapped the entire board but the music from the CD only sound through the left channel. All other sounds are fine, only the right channel from CD games and music CD don't work. Where should I look.

Thanks!!

Must have a bad trace or shorted Via hole. Check all the traces in this area. The Blue circle is the area where you need to check for bad traces or shorted Vias.
The red circles are the most common failed spots. Also check the traces for that same area on the Top side of the board.

Thank you. I checked the area you point me and it's fine. Also, I traced back down to the Ic 201 and the vias are alright. So I suspect that an op amp is the culprit. I'm going to wait until the weekend when I have much time.

Thanks!!
