QuestionSir-
I just picked up an older (1988) Nakamichi OMS CD player from EBAY in mind condition, with the original box and packing. When I plug the unit into any standatd DC power outlet- or the back of my Receiver, I press the CD's power/Off-On switch and get nothing. The unit makes a very temporary "clicking sound" when the "On" button is depressed. The green LED display lights up momentarily (1 second), but then the unit powers off as if it's not getting any current to keep it on. Any ideas? Is it a contact-hardware issue? An age issue?
AnswerDear Ron,
Where do you live? Standard electrical outlets in the US--and indeed a great portion of the world--are alternating current or AC versus direct current or DC. Most hi-fi products that require 110-240 volts (depending on where you live and how your electronics are configured) of AC power. There are some that require only a small amount (6-9 volts) of DC power, but those applications are mostly mobile, that is, for cars and boats.
If your power is really AC, then check the rear panel of the unit for its power compatibility. For instance, in the US it will be 110-120 volts at a frequency of either 50 or 60 cycles per second; in Europe and Asia it will be 220-240 volts at the same frequencies. It could be that your unit is designed for use in a 220-240 volt environment, and you live in a 110-120 volt locale. You can find out more about international electrical standards at http://kropla.com/electric2.htm
If none of this is the cause, then the unit itself has issues. If it's in unused condition, then the age should be immaterial. You may have to have it checked out by a qualified repair technician--that is, if you can't get your money back.
Good luck. And thanks for choosing allexperts.com!
Kindest regards,
