DUO with "please set disk"

[kisaku]

Hello, before touching something i would like to ask here.
My DUO black is doing "please set disk" when i put a game disk. Audio disks work but sometime audio goes bad. Is it a Caps problem or a calibration lens problem?
Thanks

It could be either. Start with a cap job first. If your system hasn't had them changed yet they should be done anyways.
