Hi guys, I use this topic to avoid opening another one.
I decided to bring back to life a dead CDR² unit. I know mine had a middle gear issue, and send my regards to PC Kid from the French forum dedicated to NEC consoles, who provided me a new gear, that he made with a supplier he know. The easy part with the old one is it turn into dust very quickly with age.
Once done, I removed the little plastic chips stuck in the grease, check the complete rotationof the new gear and I used a original game and I did face to the "Wait a Moment" issue.
Ok so the CD spin it's a good point, but I decided to test first an audio CD, Tesseract Altered State, tracks are detected quickly then only scratching noise when attempting to read then stop quickly. I decided to adjust directly last pots while reading.
For that I removed the bottom case, put down an isolation paper to avoid short and give it a try on VR105.
the audio came back and the reading seems smoothy with less mechanical noises.
I did try a CD game (Spriggan) with success but I encountered some issues with SCD.
With Deden no Den I had Macroblocking picture right after launching the game and with Emerald Dragon green screen.
I think I'm not too far from fixing it, and I think perhaps I'll have to check again the VR105 (Voltage control oscillator right ?) I can have an oscilloscope for testing RF pin, so any screen example will be appreciated.
Thanks.
