Pc engine DUO mute

[Arthur-Otaku]

I'm having problems with my Pc engine duo, the sound was gone, it's a internal problem, not an problem in cable, the sound is extremely low and I only hear anything with maximum volume of my TV. Any idea or sugestion? Thanks

Very common problem. No fix yet, as some component in your audio circuit is burned out.

I use Duo's like that for parts. Sorry!
