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 3D HIGH DEFINITION VIDEO CAMERA - HDC-SDT750 - HDC-TMT750 - SERVICE MODE – ERROR CODE – FACTORY RESET - DISCHARGING THE FLASH CAPACITOR

PANASONIC 3D High Definition Video Camera - HDC-SDT750 - HDC-TMT750 - Service mode – Error code – Factory reset - Discharging the flash capacitor

Category: Digital Camera Repair and Service

How to enter to service mode
Factory reset procedure
Flash capacitor discharging

PANASONIC HDC-SDT750 - HDC-TMT750

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.
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
Replacement Procedure
1. Remove the MIC AMP P.C.B.. (Refer to Disassembly Procedures.)
2. Remove the Lithium battery (Ref. No. “B6401” at component side of MIC AMP P.C.B.) and then replace it into new one.

NOTE:
This Lithium battery is a critical component.
(Type No.: ML-614S/ZTK )
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.

How to Define the Model Suffix (NTSC or PAL model)
There are seven kinds of HDC-SDT750/TMT750.
a) HDC-SDT750PP
b) HDC-SDT750EB/EF/EG/EP
c) HDC-SDT750EE
d) HDC-TMT750GT
e) HDC-TMT750GK
f) HDC-TMT750GD
g) HDC-SDT750GC, TMT750GC
What is the difference is that the “INITIAL SETTING” data which is stored in Flash ROM mounted on Main P.C.B..

NOTE:
After replacing the MAIN P.C.B., be sure to achieve adjustment.
The adjustment instruction is available at “software download” on the “Support Information from NWBG/VDBG-AVC” web-site in
“TSN system”, together with Maintenance software.
