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.
