Marantz CD67-SE

[aaronlubelski]

My Marantz CD67-SE does not read CD. When pushing the play button, the display blinks but nothing happens.

Some ideas how to fix it?
Does anyone have a service manual with schematics to troubleshoot the problem?

thanks, Aaron

Hello,

check if all voltages and the cd transport and laser movement are ok. Clean lens. Try to increase laser current.

This can help maybe - cd6000 is very similar

Thanks. I have checked most of the obvious voltages and they seem to be fine. All the movements are fine as well. How do you increase the laser current?
Unafortunately the 6000 schematics is quite different from the CD67.

Additional ideas ?

Thanks in advance, Aaron

Hello!
Do a search for the CD63 schematic, believe it's the same except the board layout...it's big, too
Cheers

The diagram for the CD63 may help, it can not be that different than the CD67.

Please post or send me the link. My e-mail is aaronlubelski@yahoo.com

thanks in advance, Aaron

Try these:
-switch off the unit
-open the top cover
-spin the spindle motor to check whether it's spining action smooth or not.
-if the spindle motor is ok,gently push the lens away from the spindle motor
-switch on the unit
-the lens should travel towards the spindle motor
-after it"hit" the end,the lens should move upward and downward few times,a not very visible red light should be seen
-insert a good CD,
-check the motor would spin or not.
-if the motor start spining,check if any tiny red light shining on the bottom side of the CD(it can be on the top side too)
-some sort of hiss sound maybe heard when the unit trying to read the content of the CD

Try these steps and inform me about your result🙂

Hi,

the cd67Mk2 is very similar to the CD6000 because both players are using the same servo units (Servo Driver 3x TDA7073A with Servo Controller SAA7372), the power supply is nearly identical but the cd6000 is working with two dac-units. I do not know the cd67se maybe this one is using the same stuff like the cd63 (Servo Driver 3x TCA0372 and Servo Controller TDA1301) ??? But anyway what kind of servo units are used - Power supply, dac section and the laser part are similar. The mainboards of all these players starting with CD43, CD53, CD63, CD67Mk2, CD6000 etc. are looking nearly identical but the parts are somewhat different.
