REPAIRING AND NOT THROWING AWAY

REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

Richtige Fernseher haben Röhren!

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.

PANASONIC HC-X900 - HIGH DEFINITION VIDEO CAMERA - HOW TO ACCESS TO SERVICE MODE – HOW TO REPLACE THE BATTERY – FACTORY RESET

Panasonic HC-X900 - High Definition Video Camera - How to access to service mode – How to replace the battery – Factory reset


Panasonic HC-X900:  How to Discharge the Capacitor on Flash P.C.B.
CAUTION:
1. Be sure to discharge the capacitor on FLASH P.C.B..
2. Be careful of the high voltage circuit on FLASH P.C.B. when servicing.
Before disassembling, perform "6.4. Forced full flash emission" for discharging capacitor.
The capacitor also can be discharged according to the following procedures.
Discharging Procedure
1. Refer to the disassemble procedure and Remove the necessary parts/unit.
2. Put the insulation tube onto the lead part of Resistor (ERG5SJ102:1kΩ /5W). (an equivalent type of resistor may be used.)
3. Put the resistor between both terminals of capacitor on FLASH P.C.B. for approx. 5 seconds.
4. After discharging confirm that the capacitor voltage is lower than 10V using a voltmeter.
How to Replace the Lithium Battery
1. Remove the SD OP P.C.B..
2. Remove the Lithium battery
NOTE:
This Lithium battery is a critical component.
(Type No.: ML-614 Manufactured by Energy Company, Panasonic Corporation)
It must never be subjected to excessive heat or discharge.
It must therefore only be fitted in requirement designed specifically for its use.
Replacement batteries must be of same type and manufacture.
They must be fitted in the same manner and location as the original battery, with the correct polarity contacts observed.
Do not attempt to re-charge the old battery or re-use it for any other purpose.
It should be disposed of in waste products destined for burial rather than incineration.
Service Mode
1. Indication method of the service menu
Set the mode switch "Motion Picture Recording" mode.
2. While the power is turned OFF, keep pressing the "POWER" button, "Zoom lever" to W side and "iA/Manual" button for more than 3 seconds until the top screen of the Service Mode Menu being displayed.
