Question about Audio Players & Recorders

1 Answer

I have a kenwood KA 1060 amp, and recently changed the fuse on the first PCB board where the mains power lead connects to the unit as the fuse had blown. After doing so and testing it again the fuse has blown immediately again after two more fresh fuse changes. Do you know the source of this problem? Thanks!

Most likely the output transistors are shorted. This causes the output stage to draw too much current and blows the fuses. Expect a parts cost around $20-$40. Add in the local labor rate for the total repair cost.

Hi my kenwood ddx814 just turn on a red light in the bottom and a blue light in the top noting else working


The 2 din unit you have have sounds to me like you need to re set the unit.(if no re set button is present you will need to disconnect the ISO or other leads then re connect them)
If this fails you may have a problem with the internal power supply and this will need to be fixed by an audio engineer.
You do not say if the unit had any problems before the unit failed.
It is worth noting that large 2 din units i have seen have a problem from the PCB to the ISO connector but this is inside the unit.
The problem was that the soldering on the PCB was quite weak and this did lead to the connection becoming hot and the PCB etching lifting from the PCB.
This may not be the case in your unit but it is indeed prudent to have the unit looked at by an audio engineer but this will cost quite a bit so if you have a warranty use it.

Not getting power


Pull the fuses and check them. Make sure that the wires have power. Battery power should always be on(12V) and the remote wire should have power only when you turn on the radio. Also check to make sure you have a good ground to chassis. If your wires have power and the amp's fuses are fine, then the amp's fried. At that point if it's not under warranty, open it up and see what you find. I may be a cold solder point that need re soldering or a burnt lead on the PCB board. Pay close attention at the power end of the amp, where you hook up your wires, check around there especially.

I HAVE A CANON IR 3300 MACHINE I HAVE ERROR E00000-000


WHAT: Either the main thermistor doesn't attain 30?C 1 second after the power switch is activated or it doesn't attain 70?C 2 seconds thereafter.

WHY: It has a faulty fixing film unit, lack of connectivity with the main thermistor, lack of connectivity with the fixing heater, a faulty main power supply PCB, or the DC controller PCB is faulty.

NOTE: You can reset the error by performing the following in service mode: COPIER>FUNCTION>CLEAR>ERR.

CONNECTOR FIX: Make sure that the connector of the fixing assembly is seated.
A. main power supply PCB (J8) relay connector heater
B. DC controller PCB (J320) relay connector thermistor

FIXING FILM UNIT (THERMISTOR) FIX: With a multimeter, check the interval between pin 1 & pin 2 & between pin 3 & pin 4 of the connector (4-pin) of the thermistor for electrical continuity. A result of ?? means that the circuit is open (lack of connectivity). Resolve this by replacing the fixing film unit.

MAIN POWER SUPPLY PCB, DC CONTROLLER PCB FIX: Press the Start key. If the drive voltage of the heater is supplied by the connector J8 of the main power supply PCB, then the main power supply PCB should be replaced. If not, then the thermistor control mechanism is faulty & the DC controller PCB should be replaced. Use the following to ascertain this:
Main heater: between J8-1 (FSR1) & J8-5 (FSR COM)
Sub heater: between J8-3 (FSR2) & J8-5 (FSR COM)

Kenwood KAC 7202 amp not powering on


First you should test to be sure the amps main power feed is supplying 12+ volts to the amp. and that the other connections (head unit remote lead - input & output signal leads) are properly secured, if all is well then there maybe an internal issue with the amp.

It is not recommended to affix an amp directly to a speaker/kicker box, hence the vibration that may cause wire connections and/or internal electronic components to become loose or faulty.

As far as "should i take the amp apart and look at its guts"

NO, sorry but given the way you phrased your question I can assume that your electronic troubleshooting knowledge is not up to par, and that task would be a waste of your time.

Good luck

My 800 watt kenwood


Sounds like you shorted out the main power wire somewhere and killed the amp. Is the amp on the fuse intact or blown? Do you have 12 volts at the amp? check you connections and see if it helps.

Video output not working


it sound to me like you have a broken connection on yourvideo out jack on the main unit becouse you say the lead is fine and the tv screens work with another unit.this can be caused by the plug being pulled out in a wrong angle. ask an audio dealer to chech the solder connections in the unit to see if they are making a connection with the pcb(printed circuit board. hope this helps
