Software Recovery Tool for BA Board
111A
SYMPTOM
No picture may appear, while the green LED is on.
CAUSE
Damaged NVM data on BA board.
SOLUTION
Recover the TV set by applying the Software Recovering Tool using a Memory Stick.
1. Preparation – Memory Stick Requirements
x Remove unnecessary files from the MS before copying data.
x Use a Memory Stick formatter to format. Windows formatters are not supported.
x A format program can be downloaded from:
http://support.sony-europe.com/memstick/downloads/downloads_ms.asp?l=en&f=MSFRM#disc
x It is, however, recommended to use a Digital camera to format!
x After formatting, the content in the MS is just a “Memstick.ind” file.
x The flash size must be 16 MB or more.
2. Recovery procedure
2-1. In the Memory Stick, create a folder “eg2l_dvt” containing a subfolder “swupdate”.
2-2. Download the attached zip file, including the software recovery tool (RAM file) and NVM data (TAR file),
attached to this Technical Bulletin.

2-3. Copy the RAM file in the “eg2l_dvt/swupdate” folder.
2-4. Copy the TAR file into root directory of the Memory Stick. The MS root fold er should look as below (Make sure
that ‘Show hidden files and folders’ is activated in the Explorer Options).
2-5. Power off the set and unplug the AC cord.
2-6. Insert the Memory Stick into the erroneous BA board and turn on the TV.
2-7. Wait for about 30 seconds until “Initial setup” is shown. If you can see the EMMA log, wait until the EMMA
application is launched.
2-8. Turn off the TV.
IMPORTANT
After the recovery process, the TV can go in Error mode, i.e. LED changing from green to Red blinking 14
times (T-Con error) – due to generic NVM data not matching to current set size. Therefore, make sure to
write the correct NVM vers ion.
2-9. Follow the BA board replacement procedure as described in TB 09TV097. Although the BA board does not
have to be replaced for this issue, it assures correct settings and memory values for each model.
2-10. Update to software package #1.700 or higher, using the software attached to TB 09TV093.
2-11. Check the MAC Address value in Menu => Settings => Network settings => Network.
NOTE
: If the MAC address is empty (6 times “00”), this board cannot be used and must be returned for central
repair.
