Hi
I dont speak dutch, but it looks like you have a mx6000 stand, but you have a mx8000 tv.
You can use the same stand, but just swap the motor for one with 5 pins.
I have a motor for a mx8000, the plug on the cable has 5 pins. I would sell it to you for £65 including delivery to Holland.
Payment would be by paypal only.
Let me know if you are interested.
Graham
