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.
Service Mode

Cutting of battery connection or AC power supply connection to end the service mode.
CAUTION  (When servicing FLASH P.C.B.)
1. Be sure to discharge the capacitor on FLASH P.C.B..
Refer to “HOW TO DISCHARGE THE CAPACITOR ON FLASH P.C.B.”.
The capacitor voltage is not lowered soon even if the AC Cord is unplugged or the battery is removed.
2. Be careful of the high voltage circuit on FLASH P.C.B..
3. DO NOT allow other parts to touch the high voltage circuit on FLASH P.C.B.
Factory Setting
PROCEDURE
1. Set the mode dial “Motion Picture Recording” mode.
2. Turn the power on, and then while keep pressing the “Zoom lever” to W side, “Intelligent auto/Manual” button and “Menu” button for more than 3 seconds until the top screen of the Service Mode Menu being displayed.
3. Touch the [ 1 ] of LCD.
4. Touch the [ YES ] of LCD.
