Title: PC Engine Duo CD problems
Post by: pauljh on April 14, 2015, 05:04:38 AM

Hi All,
  Anyone give any tips on fixing a PC Engine Duo CD drive?, the drive sounds fine, picks up the disk and then either spins for ever (with a black screen) or crashes after spinning for 30 seconds with a black/red screen (think a large black cross on a red background).

   Idea's?, pointers?  Ta!

This is the best place to start looking/testing -  http://www.pcenginefx.com/forums/index.php?topic=8926.0...probably would have been best to place in the repair/mod section...

does it plays audio cd fine, if not, could be the lens dirty, 100% isoproprol alcohol (never use less than 100 on a laser lens) and lint free tabs will clean it in no time.

if it reads cds then could be a hard ware issue inside

I don't think you can make 100%. You can find 99% though.

Well an Audio CD does spin and says its playing but no sound, BUT this may be because its got a hardwired scart coming out of the unit which doesn't carry CD sound (actually that doesn't sound right at all?).  I've tried a legacy old game and it just sits at "just a minute..", I burnt a copy of Dracula X on a taiyo yogen at slow speed and that gives the black "cross" effect..
My next question is how come noone's created a CD emulator that loads images from SD for the PC Engine CD yet (like the PSX one nearly completed)??? (or have they?)
