Special Software Instructions for BAL Board or

LCD Panel Replacement

The 2010 models utilize a “generic” type BAL board. In the past, many different main boards needed to be stocked due to differences in software requirements. The software loaded on the board was specific to the model and its features along with the type of LCD panel installed during production.

Replacement BAL boards will now be stocked with basic software. Once the replacement board is installed in the unit, the most current software is to be installed using a USB storage device containing the necessary software downloaded from the ASC support web page.

In addition to software installation for specific models, 2 items must be checked and adjusted in the service mode. The adjustments are Segment Data (model ID) and Destination (region ID). The procedures for the software installation are located on the ASC website (http://www.sony. com/asp). The adjustment procedures are located in the service manual.

This new method of supplying main boards significantly reduces the complexity of replacing LCD panels and main boards. Information about the LCD panel is stored on the TCON circuits. This information is automatically loaded onto the main board when the unit is powered up. The need to lookup data in the LCD panel manual is no longer necessary. With the correct software version and proper settings of the Segment and Destination data the BAL board and/or the TCON or LCD panel can be replaced more efficiently.
