Subject: Firmware upgrade (ver. 47.09) to reduce Field Effect Transistor (FET) failure in SC board.
Cause: Vertical sync pulse from D board to SC board is not always synchronized. As a result, the over current
damages the FETs.
Firmware Upgrade Preparation:
1. Firmware data is stored in the D board (Part # TZTNP01HJTU).
2. Download firmware upgrade file (UpgradePZ700U.ZIP) from Extranet.
3. Unzip and extract files to your computer and then copy to the root directory of a SD card as shown below:
