My screen on my kenwood dnx 6990hd says (DC OFFSET ERROR) What does thay mean


Basically that means there is an overload or some form of power issue with the machine.
The best thing to do is reset the unit to start with. Do you have the manual?

Kenwood with dc offset


DC offset is most often caused by the bias level for the output transistors changing for some reason. This could just be that the control is dirty and needs to be cleaned and re-adjusted, or the biasing network has a problem, most likely the diode or transistor that is being used to set the reference. The diode or transistor is often mounted to the heatsink for thermal feedback, which allows the bias to change depending on how hot the output transistors are getting, There is no mention as to how high the DC offset is. The usual range for DC offset adjustment is less than +/- 1 volt. If your offset is higher than this, there usually is a problem with the bias circuit that needs to be repaired. If it is MUCH higher, then one of you output transistors or driver transistors is most likely defective.

Error u60


code u60: Job offset home position sensor does not detect home position for the Job Offset Assembly.

check
home possition sensor actuator
home posiition sensor
sns harness ... is there any damage or misalignment. replace broken parts.

if that did not help
Test the job offset home position sensor.
run the service diagnostics offset home position test.
Does the sensor function correctly?
If yes you well have to replace the engine control board. That will give you that error. Hope this helps if you need more help let us know at iteminconline.

DC Offsets on output - protection don't allowd to switch on


you don't want to do this( bypass the protection0
that d.c. output will burn the coils in your speakers with out making a sound!! you have a biasing problem
or like you said a d.c. offset problem it is best to work on this problem with out a load on the amp, this will allow you to trace back where the trouble is starting at. caps will cause this sort of problem but leaky transistors can also do this, even diodes.
this will require an experienced trouble-shooter.

What does the offset light mean on sony xplod amp


THIS IS "DC OFFSET". MOST AMPLIFIER PROTECTION CIRCUITS REACT TO THIS CONDITION BY SHUTTING THE AMPLIFIER DOWN. THIS IS A CONDITION, NORMALLY BROUGHT ON BY SHORTED OUTPUT TRANSISTORS, THAT ARE TRYING TO PASS THE POWER SUPPLY DC CURRENT TO THE SPEAKERS, WHICH IN A MATTER OF SECONDS, WOULD BURN THE VOICE-COILS IN THE SPEAKERS. MOST TIMES THIS WOULD BE CHARACTERIZED AS HOOKING THE SPEAKERS UP AND OBSERVING THEM SIMPLY POKING OUT OR IN CONSTANTLY WHICH CREATES MUCH EXCESS HEAT. THIS IS WHY THE AMPLIFIER WILL SHUT DOWN TO PROTECT THE SPEAKERS. YOU CAN TRY TO DISCONNECT THE SPEAKERS AND THE RCA INPUTS THEN POWER THE AMPLIFIER UP. IF THE DC OFFSET LIGHT STILL ILLUMINATES, THEN YOU WILL HAVE TO HAVE THIS UNIT REPAIRED. ONCE REPAIRED, BEFORE REINSTALLING IT, MAKE SURE TO CHECK YOUR SPEAKERS FOR DAMAGED VOICE-COILS, WHICH COULD HAVE BEEN THE PRIMARY CAUSE OF FAILURE. OK. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE....V
