Thanks for reply, caps were replaced and I dont see any bad trace, so I think this console hasnt solution.

@GTV reviews the Cosmic Fantasy 1-2 Switch collection by Edia, provides examples of the poor English editing/localization work. It's much worse for CF1. Rated "D" for disappointment, finding that TurboGrafx CF2 is better & while CF1's the real draw, Edia screwed it up... |

Console Repair/Mod Center / Turbo Duo CD-Rom issue
06/12/2018, 01:14 PM
Hi all,
I am new here, thanks to admins for activate my account. This is my first message .
I have a Turbo Duo, it was stored in a box since years...and I decided to check it because I bought a turbo everdrive.
I made the rgb mod, and its working fine. I recapped all caps too, sound is working fine now with hu-cards.
But I have a problem in cd-rom. I dont know if lens works. When I turn on the console, cd spins all time. I am not expert in Nec consoles, but this console has a push button which is pressed when cd tap is closed, right?
In my console this push button dont mind, cd spins all time. I have tested the push button and there isnt continuity, so its fine.
Lens is always in the same place, motor which moves the lens has 4V, I dont know if this is correct. I have tested traces and all is ok too.
Sorry for my English, I have recorder 2 videos. I have only a cd-r burned at 1x and a music cd to test cd-rom drive.

In my dropbox folder there is a pic too. In this pic, as you can see, I have replaced a 220 Ohm resistor because there was continuity. I have continuity in L101 too (in his extremes).
If anyboy can help me...
I have only a tester, no osciloscope or similar.
Thanks in advance.
