[Console Repair/Mod Center / Re: CD-ROM2 Potentiometer Reference Images]

   Alrighty, so I had some success! I started off with Vimtoman's photo which got me back to disc's spinning but not reading. Got the "Please set Disc!" error...

   Then I followed up with the guide LowRes posted. I used an audio disc, removed the cdrom2 from the briefcase and plugged in power and headphones directly, flipped it upside down and started making some minor tweaks to the pots until the audio wasn't garbled anymore. Tested the skips and everything seemed to be operational. Popped in a disc of Dungeon Explorer II and sure enough it fired up.

   The biggest improvements came from the 102 pot. I could literally hear the audio clearing up in real time while I tweaked it. I can't tell if it's 100% perfect because I don't have any other experience with pc engine disc games to compare but this was leaps and bounds better than staring at an error screen and having a non spinning drive.

   I had to search for "calibration" to find Vimtoman's photo of the potentiometers in case that helps anyone in the future. Maybe someone can add it to the calibration guide or sticky it somewhere. It's a great starting point. Thanks for everyone's help!

Howdy folks,

  Picked up a faulty CD-ROM² drive. Need some reference images of the potentiometers so I can get a baseline of where I should start. The one I received had them all turned to one side. I've played a little bit around with it myself and have gotten it to spin up at one time but never could get it to read the disc.

   If anyone can post up a quick photo of their working units POTS I'd be super grateful. Thank you! Might help some other people in similar situations.
