Title: Turbo Duo dont Read CD games but read audio cds
Post by: Dsantos82 on September 12, 2024, 09:25:00 PM

Good afternoon everyone, I have a problem, I recently imported a PC ENGINE TURBO DUO from Japan, the system reads audio CDs well but the games don't read at all, I did a full recap, tested it with the laser from another console that works well and have already replaced it ics 105-106 and 501 the problem remains, does anyone have any idea how to solve it, I would be very grateful for any ideas.

I've had a similar issue with a CDR-30 (suitcase CD-ROM drive) and had to tune the VCO pot.
Here's (https://www.retrosix.wiki/laser-tuning-pc-engine-duo) a nice summary of the Duo pot adjustments. I'd give that a try.
