Hi welcome to just answer
How long have you owned this?
When was the time it worked?
When you tried to press the open button, do you hear the motor running?
You might want to bring your ear close to the system to hear the sound.
Also did your dvd came with system disk?
So the standby light does not stay on when you plugged the system?
The grinding noise is only when you press open button?
I did received the pictures. I am afraid that the system might need to be taken to a local repair shop for diagnosis. The power supply has a problem and the firmware has been corrupted. I am now thinking of your repair cost vs replacement.
The tray is pushed by a motor, a set of gears and sometimes a belt. The grinding noise is coming from gears that are trying to open or close the tray when the sensor is not working.
I am limited here online to what you can do to fix the system.
Thanks for the update. The unit is from 2002 and I think it's time.
Thanks for using just answer.
