Question about Pioneer PD-M406 6-Disc CD Changer
I replace laser pickup and need to know how to get in service mode?
time to clean the lens. any electronics store will sell a cd lens cleaner. if after that it won't read, you need to take the cover off and gently clean the lens with a q-tip and rubbing alcohol. blow it off to dry. if it still won't read, you'll need to replace the optical pickup assembly.

In service (tech) mode, the technician can check the machine and perform various test to isolate the cause of
a malfunction. While in Tech mode, the machine still performs all normal operations.
To enter the Tech Mode
To enter the Tech Mode, press "Menu + Back + Left + Right + OK + Stop + Menu" in sequence, and the
LCD briefly displays 'Tech Mode', the machine has entered service tech mode.
After entering the tech mode, select the item you want by using a button on control panel.
Scroll to Pickup roller.
I cannot see what comes up on the screen after this but I imagine it will ask if you wan to reset this counter. Press ok and that should do it. You may need to power down but I don't know.
