Re: NAD 502 CD player LCD problem

I had the same problem, and miguelovitch's solution and site were very helpful. I was able to replace the burned out bulbs with two white LEDs. The trick was determining that the power supplied to the bulbs is 15 volts DC. Once I figured that out, I picked up Radio Shack part 276-0017, 2 5mm high brightness white LEDs, and some 560 ohm resistors to drop the voltage to the LEDs. (The online LED circuit calculator I used sugested 470 ohms, but I went one higher for safety.)

The results are quite satisfying, though I should not have pointed the LEDs directly at the display becuase they do make a bright spot.

Now if I can only figure out how to get my home theater receiver's remote to control the CD player!

Hi, I have a NAD C541i cd player when i turn it on i get three blue line on the display, i open the draw and insert a CD disc but the blue lines stay on the display and the disc don't play. can you...

The blue lines you mention should flash when trying to find
the 'Table of Contents' of your CD, even if a CD isn't loaded.
If when a CD is loaded and these lines flash for a while without
any CD info e.g track no. / disc length then it's more likely that a problem has occurred with the laser.
Various NAD CD players use the Sony KSS-213 Laser unit
and for some reason particularly with NAD CD players, they tend
to drift out of calibration over time so what i usually do when i come across this is very finely adjust the pot trim on the laser itself and testing a CD between adjustments.

NAD C521 on / off button light

"POWER ON: Press this Green button to switch on the power to the disc player from Standby mode. The LED will change from Amber to Green, and the EFL display will illuminate."

So besides the L.E.D. the unit has another visual indicator that it's turned ON, the display lights up. Is this worth pursuing a fix?

Nad 502 CD will not recognise and play CD every time

HI.This will occur when the optical assembly becomes unstable. this ((Whole One Piece)), assembly incorporates the spin/load motor, optics housing /arm, tracking device and tracking rail. This is connected to the loading dock assembly. This 'NO Disc' or CD NOT PLAYABLE, code is the result of a failed or burned out lens, or misaligned loading mechanism. It is possible that you have a dirty lens cap. you can try using a cleaning disk in this case to confirm actual lens failure. if the cleaning doesn't restore normal reading capabilities, this will confirm my diagnosis.

You will need to have the optical assembly replaced in this case. once replaced, your unit will be able to read and track once more

Nad cd player cd541i noise

That one is going to need Tech service.

I've worked on several of the NAD players.

Sounds like a focus or gain adjust needed.

Nad c520 high pitched ringing

Hi, From your description, it sounds as if the noise is coming from the circuit that controls the display backlight. If I recall correctly, the C520 has an EL backlight just like the C521 (which I have one of). On the front of the circuit board, there should be a little yellow trimmer potentiometer that controls the brightness of the display. It may be that the noise will go away if the brightness is turned down some. If  the noise varies as you turn the controller, but doesn't go away completely, the backlight may need servicing.
