Color
TFT LCD Module is very sensitive both electrically and physically. Users, are
requested to follow the Guidance of handling color TFT LCD Module on the
followings.
Be careful not to make scratch on the polarizer.
Surface of polarizer is soft and can be physically damaged easily.
Do not touch, push or rub polarizer surface with materials over HB hardness.
Keep clean the surface.
Wear rubber glove when touch the surface of LCD screen. Please use soft and anti-static material as cleaner.
Keep out of water.
Water on/in the LCD may cause electrical short or corrosion. Please wipe out dry or water carefully.
Prevent swift Temperature & Humidity change.
Instantaneous temperature and/or humidity change can make dew or ice which cause non conformance such as malfunction.

Prevent swift Temperature & Humidity change.
Instantaneous temperature and/or humidity change can make dew or ice which cause non conformance such as malfunction.
High temperature & high humidity reduce the life-time.
LCD is not proper to be used at high temperature and high humidity. Please keep specified temperature and humidity condition.
Keep out of Corrosive Gas.
Corrosive gas affects the polarizer and the circuit chemically and cause defects accordingly.
Electrostatic discharge can make Damage
There are electro-static sensitive components such as CMOS in LCD Module. Please earth human body when handle the LCD.In addition, do not touch the interface connector pin with bear.
Do not operate for a long time under the same pattern
Operating LCD for a long time under the same pattern can cause image persistence and can damage it. Please follow following guidance.
1. Turn the power off when do not use.
2. Change the pattern periodically.

PC mode can be entered by pressing PC button on the remote controller. User can return back to TV mode by pressing the PC or TV buttons.
After the switching to PC mode, VGA input will be displayed on screen, as soon as the mode (input resolution and frequency) is determined.
If there is no input from the VGA input, NO SIGNAL dialog will be displayed for 15 seconds. At the end of this period if there is no signal from VGA input, the TV will go to Sleep State. While in the sleep state, the TV will keep monitoring the VGA input. If VGA signal is detected, the TV will wake from Sleep State, to PC mode. Alternatively, the user may select to switch the TV on from Sleep State, just like switching on from Stand-by. In this case, the set will switch on from TV mode.

The MP1593 is a
step-down regulator with an internal Power MOSFET. It achieves 3A continuous
output current over a wide input supply range with excellent load and line regulation.
Current mode operation provides fast transient response and eases loop stabilization.
Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown.
Adjustable soft-start reduces the stress on the input source at turn-on. In shutdown mode the regulator draws 20µA of supply current.
The MP1593 requires a minimum number of readily available external components to complete a 3A step down DC to DC converter solution.
