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!

"No disc" message while CD is in


either a dirty or bad optical pickup in the unit that reads the disc so it can play.

Unit works fine but LCD display does not illuminate. Can be seen in a low ligfht room but it does not light up like it did for years. Do these LCD displays just die???


The older LCD's have backlights hidden behind the display that burn out over a period of time, this is a tricky repair because the unit needs to be stripped down and the covering removed. Soldering skills for most jobs will be required.

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.

Seems a lot of reports like this have been noted and unfortunately the FIX cost more than replacing the electronics. My suggestion...make your move to a new unit.

Top console is not working on Pro 1000 Dual Scratching CD Player


Check controller cable between base and remote. Look for bent pins. If appears ok, you may have an internal loose connection. Try and narrow down if loose section is on base or remote. You could have it resoldered if needed. [email protected]

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?

I have the same problem and it's due to dirt!
I'm going to try using compressed air, but -
this definitely works:

:) Seriously:

tilt the cd player to a 45 degree angle (flat, basically - as if they tray were horizontal.)

I had my player for 10 or 12 years, and this problem is only coming up now. My house gets very dusty.

Also - vertical load disc players are hard to clean. X_X (inside the disc tray)

I love this stereo too!
I don't want to have to go out and buy another stereo!
