Resolder all the resistors. They say 2.7 in the manual, but the print on the component is 2R7. For solder use 60-40 rosin core with flux. The thickness should be a small diameter, but most any solder will work, you will only be putting a very small dab of solder on each solder connection. Just enough to make it melt and reflow, no more. This is no guarantee that it will fix your unit, but it is the most common cause. You may find that the display being out for yours is something different. If you have a voltmeter you can put the radio on a bench and check the voltages (DC) on those resistors when it is powered on. You will need a small power supply capable of about 3 amps to power up a car stereo. I don't remember what the voltage are supposed to be, but you should start at one end and have a high voltage and as you go from one resistor to another, the voltage will go down in equal increments. It is a voltage ladder and with all the resistors being the same value, you should have the same voltage across each resistor.

NAD C320 BEE - goes silent. Only yellow light.


Hi,
Just came accross your post accidentically, while reparing my own C320BEE. May be it 's too late for you now, but it could help others: I had the very same symptoms as you described and after a long search found out that the trouble was R45 in one of the 18V regulators. (R45: 33 ohms 1/2W fuse resistor, situated more or less half-way between the two "metal towers" on the main board. Replace by a somewhat stronger type 1W or so.
Likewise R46.)

Kenwood cd player kdc4060ra


SYMPTOM: No Display.
COUNTERMEASURE: Re-solder the following components on PCB X34-415:
R43, R44, R46, R47, R48, R49, R50, R51, R55, and R57.

Ok so if you remove the top of the unit and cd player down the right side you see a line of surface resistors that say 2R7 on them, they all need to be resolders to the bord theres 9 total.

Hey did u find the curcut # on the kenwood kdc-x590 if so pleas let us know !!! thanks for ur time


Are you talking about the circuit that lights the display? If so, you need to resolder the surface mount resistors in the front right corner on the top of the board. Front right while facing unit with top off and CD deck out. you will see a series of surface mount resistors and they all are connected in series. All of them need to be resoldered. That will make the display work again.
