4. Software Updating
You can update our PDP's software through a special RS232 cable (shown as below).
9 PIN D-SUB FEMALE 3.5 mm Stereo Earphone plug
This RS232 cable includes a 9 PIN D-SUB FEMALE, a 3.5mm Stereo Earphone plug and 3 wires.
Built the cable as shown.
UPDATING STEPS:
1. Prepare a PC, and unzip update.zip;
2. Connect the cable:
connect the 9 PIN D-SUB FEMALE end to a computer, and connect the stereo
earphone plug end to RS232 terminal on the back panel of the PDP;
3. Run the application FlashUpgrader.exe, then choose bootcode.inf in the dir bin,
appoint a correct COM port (e.g. COM1 or COM2) and click Flash;
4. Turn on the PDP and the updating process begins. (Warning: Must not turn off the
PDP in the updating process!)
5. Run the application FlashUpgrader.exe, then choose pwSDK.inf in the dir bin, and
click Flash;
6. Restart (power off and power on) the PDP and the updating process begins.
(Warning: Must not turn off the PDP in the updating process!)
7. When the updating finishes, the PDP will restart and work with a new version of
firmware.
PDP Service Manual 2005/07/06
Turn off the TV first, and then disconnect the RS232 cable (to avoid damage to the
RS232 of the PC).
5 Display Cell Defect Specification
In some cases, a panel may have defective cells that cannot be controlled.
These defective cells can be categorized into three types;
(1) Non-lighting cell defect : defect in which the cell is always off
(2) Non-extinguishing cell defect : defect in which the cell is always on
(3) Flickering cell defect : defect in which the cell is flickering
The display cell defect specifications define the allowed limits for display cell defects and
are used as the criteria in determining weather a panel is shipped.
