Console Repair/Mod CenterQuote from: NightWolve on 05/05/2018, 10:27 PMSure! But didn't you say the CD doesn't even spin ? You got other problems to deal with before even thinking about this I think ??Yup, it wasn't spinning at first, but it was troubling me and had spare time on the weekend so I decided to give the first page tutorial a go.
As a starting point I used the xls file where a forum user wrote his ohms readings on the pots of a working Turbo Duo, and then I started tweaking using BlueRaven's and BlueBMW indications on the first page of this post. I got it working to the point that some original music cd's worked (minus some slow loading and a bit of trouble reading con the outer tracks) and the five or six burned games I tried worked alright. I knew it wasn't a permanent fix, but I was able to play games.
But yesterday I tried to hook up a small 2MHz portable oscilloscope to try adjusting the pots using your tutorial indications and couldn't get a proper waveform so I assembled again the console and called it quits. I don't know what I touched, but the thing is that now it has problems reading CD's again, so I guess I'll reset the pots to the starting point and and try to get it at least reading burned CD's.
I think the moral of the story is: "You need proper tools and knowledge to do a good job" or also "If it's working don't fix it!"
Here are some pics during the process:
