Good evening everybody, does anybody have the pc engine duo block diagrams please?
I've totaly recap my duo but the led doesn't light on. I've 4.95v at both legs (A - K).
I think i've a shortcut Somewhere but i don't have the video cable to check if the pc engine goes on or not. The Lens moves just a little bit but the cd doesn't turn. Maybe the Lens is out of service.
Would like to check all the signals i Can, but need the schematics to do this correctly.

Hope somebody Can help.
Thanks.

Wish you all merry Christmas.

The LED only comes on when hitting run on the controller to start a CD game. It's not a power light.

You could temporarily connect a spare RCA cable to the AV jack by just soldering to the pins on the AV port to test. It would be good to know what the CD bios screen says or does when the system is powered on. You might not even be getting the CD bios screen to show up when the system is powered on.

I enjoy fixing these systems

tron: I hate strictlylimitedgames jash even more so when they get the rights for physical release of anything by taito. Feb 5, 2023 11:22:34 GMT *

spenoza: It occurs to me that this same limited physical release approach has hit other hobbies as well, like tabletop role playing games. Companies in that space that aren't Hasbro are all small and so they tend to do limited prints of books and then lean on pdfs. Mar 8, 2023 20:23:43 GMT
