Please do not attempt to disassemble this device, if you don’t have needed tools and sufficient experience. This is not an easily repairable device for a customer. Contact the service centre for Panasonic to get it repaired. No user repairable parts inside.
How to Replace the Lithium Battery
The lithium battery is a critical component.
(Type No.: ML-614S/DN Manufactured by Energy Company, Panasonic Corporation)
It must never be subjected to excessive heat or discharge.
It must therefore only be fitted in equipment designed specifically for its use.
Replacement batteries must be of the 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.
1. Remove the Monitor P.C.B.
2. Unsolder the Lithium Battery "ML-614S/DN" and then replace the new one.
How to Define the Model Suffix (NTSC or PAL model)
There are eight kinds of SDR-H100/H101, regardless of the colours.
 a) SDR-H100P
 b) SDR-H100PC
 c) SDR-H100EB/EC/EF/EG/EP, SDR-H101EB
 d) SDR-H100EE
 e) SDR-H100GT
 f ) SDR-H101GA/GN
 g) SDR-H101GK
 h) SDR-H101PR/PU/GC
What is the difference is that the "INITIAL SETTINGS" data which is stored in Flash ROM mounted on Main P.C.B.
To define the model suffix to be serviced, refer to the nameplate which is putted on the bottom side of the Unit
After replacing the MAIN P.C.B., be sure to achieve adjustment.

LG DM2740 – How to upgrade the firmware, system reset, amplifier and MICOM schematic - DVD Micro Hi-Fi system


LG DM2740 (DM2740, CMS2730F) DVD Micro Hi-Fi System - Signal system: Standard NTSC color TV system
Stereo mode: 80 W + 80 W (4Ω at 1kHz)
 The pick-up incorporates a strong magnet, and so should never be brought close to magnetic materials.
 ✓The pick-up should always be handled correctly and carefully, taking care to avoid external pressure and impact. If it is subjected to strong pressure or impact, the result may be an operational malfunction and/or damage to the printed-circuit board.
 ✓Each and every pick-up is already individually adjusted to a high degree of precision, and for that reason the adjustment point and installation screws should absolutely never be touched.
 ✓Laser beams may damage the eyes. Never permit laser beams to enter the eyes.
Also NEVER switch ON the power to the laser output part (lens, etc.) of the pick-up if it is damaged.
✓ NEVER look directly at the laser beam, and don’t allow contact with fingers or other exposed skin.
 ✓Never attempt to disassemble the pick-up.
Spring has excess pressure. If the lens is extremely dirty, apply isopropyl alcohol to the cotton swab.
(Do not use any other liquid cleaners, because they will damage the lens.) 
✓Take care not to use too much of this alcohol on the swab, and do not allow the alcohol to get inside the pick-up.
