REPAIRING AND NOT THROWING AWAY

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

PIONEER DDJ-ERGO-V DJ CONTROLLER ERROR CODES -

ERROR CODES - PIONEER DDJ-ERGO-V _  DJ Controller



Error Codes Display & Jog Dial Rotation Load Adjustments _ Pioneer DDJ-ERGO-V DJ Controller


ERROR CODES DISPLAY

  When abnormalities are detected during the time of carrying out power supply ON, or operation, it displays by LED.


How to Enter JOG Load Measurement Mode

* To enter this mode, while holding the F2 and F3 buttons on the Deck A/C side pressed, set the Power switch to ON.

* During this mode, the KEYLOCK LEDs on both sides are lit.  (Hold the two buttons pressed until the opening display terminates.)


* The load (light or heavy) on the JOG dial when it is turned can be objectively judged in this mode.

How to Measure

# When the JOG dial is rotated swiftly in this mode, the maximum speed and time required for slowdown, as defined below, are measured. When the maximum speed reaches 7 times normal speed or higher, time required for slowdown is calculated then evaluated as to whether or not it is within the specified range, then the result will be indicated by the LEDs.

# Either rotation direction, clockwise or counterclockwise, is okay.

Maximum speed

Maximum speed with normal speed defined as when one rotation takes 1.8sec


Time required for slowdown: Time required for the rotation speed to slow down from 3 times to 1.5 times normal speed.

To measure the time required for slowdown, the maximum speed must be 7 times normal speed or higher.

If the maximum speed does not reach 7.0 times normal speed, the JOG LEDs flash three times as a warning.

The number of measurements up to the fourth time is indicated by the LEDs.

First measurement finished: HOT CUE 1 lit

Second measurement finished: HOT CUE 2 lit

Third measurement finished: HOT CUE 3 lit


Fourth measurement finished: HOT CUE 4 lit

Judgment

After four measurements of time required for slowdown are finished, the mean value of the four measurement results is calculated and judged as to whether or not it is within the specified range. The result will be indicated with the LEDs.

The specified range is 100 ± 40 msec.

OK: VINYL lit

NG (lighter): LOOP OUT lit

NG (heavier): LOOP IN lit


The 5th time or subsequent measurement can be performed, but the number of times of measurement is not indicated with the LEDs. The mean value of the results of all the measurements is calculated, and its result will be indicated with the LEDs.



POWER-SAVING MODE

If a drop in voltage for VBUS power is detected, a power-saving mode will be automatically established, limiting the headphones maximum output level.


Two types of power-saving mode are provided, as shown below.
