Hi, everybody!
I`m new here and need some help for troubleshooting. Have a Micromega Trio transport with CDM9 Pro. Was sent for upgrade and came home with broken ribbon/flex cables for both laser and motor. This happend during transport. Packing can never be good enough.....😱
I understood early on that getting spares for CDM9 Pro was difficult, expect for laser that can be swapped for the regular CDM9. After some exctensive searching on the web I got in contact with a german company selling new ones. Got hold of one within a week. Great🙂
Well great until assembly was ready and this happend: When I put powercord in the player the motor starts spinning at once and won`t stop. The on/off button does not react. When I put laser cable in/out of PCB contact the speed increase/decrease but does not stop anyway. After some fumbling around it suddenly operated 100% for 15 minutes and then failed again. I don`t know how these mechanisms really work and what "triggers" this behavior?
Lasers actually come in 6 different types marked 1-6. There are industrial type, CD types, Cd rom. CDM9 have nr.2 while original Pro has 4. Well mine is 6 which is the first I have seen..........
Any suggestions were to look. Laser? motor? power supply? adjustments?
Tips is most welcome!🙂

Both CDM9 (normal motor) and CDM9pro (brushless motor) was the first mechanism, where is in use a so called LDGU (hologram laser diode) from Sharp instead a normal laser diode. The reliability of this diode is significantly worse than by normal laser diode. What you have described is exactly the same fact, that I observe, if there is a bad LDGU by my service work.

Well, problem lost!
A lot of frustration, but there had to be something wrong with the powersupply and it turned out to be the powercord it self. The Micromega has a 9 pin cord and one pin was loose in one of the connectors.
Solution was so close, but yet so far away..........
Thank you for tips and help!

Hi ulle
do you have the details of the german company that you got the cdm-9 pro from?
I have a dead Micromega that needs one
Thanks C

Hi!
The company is Riedservice in Stuttgart.
www.riedservice.de
Good service and quick to answer. If you don`t live in Germany you have to make prepayment, but no need to worry. It is a serious company and they communicate well. Tracking number etc.
When you assemble the new drive take care of the flexicable and don`t do anything in a hurry. Cables are very fragile under pressure.
Good luck!

Hello, I'm new here, and in a similar boat.
I shipped a Micromega transport, and it arrived with a torn foil to the motor part of the CDM 9 Pro. So, I'm looking for a dead CDM9 Pro laser with a good motor section.
Does anyone know the part number to the motor, or what other applications it might have been used in?
Thanks, Samir.

Hello all,
I know it is a late reply but, if anyone is looking for CDM-9 Pro brushless motors.
I do have some in my possession.
Regards,
Michel

Hello ulle,
I have had those for so long that I don't even remember where they come from.
I know I took them off from CDM-9/46 drives to install DC motors so there is a good chance they could be new.
They look really clean so I wish I had an easy way to test them.
A fellow not far from me is in the process of buying one so I should know soon enough if there is a problem.

Do you still have these Michael as I am interested in purchasing one?
If so, how much are you asking for one and do the motors come with the ribbon cable that connects the motor to the drive electronics?

Hi Michel,
If you still have the brush motor with ribbon cable working for CDM9 Pro please let me know. I am interested for my CD player Theta. Thanks

Thank you for advices.
Thank you for advices.
What about this approach for reconnect torn flex leads like to find under

Links are death - often usual after several years.
the first both I have save and will upload here. But the last both are even no longer available under Wayback Machine
Maybe one of the members have save the images and can upload here
