Intermittent Video Blanking F320
SYMPTOM
Intermittent video blanking when receiving a YUV component video signal from a DVD player via the AV4 input.
SOLUTION
Upgrade the main software as explained below.
• Take a Memory Stick and check whether the root directory contains the "MEMSTICK.IND" file.
• Create the directory and subdirectory "MSSONY/TV" and copy the attached "MSHI1350.SDU" file to it.
Caution, make sure there is only one SDU file in this directory.
• Power on (the display panel should be on).
• Insert the Memory Stick. The Hitachi main controller (Flash IC) will be programmed automatically in
approximately one minute. During this time, the power LED is blinking (1 sec ON, 1 sec OFF).
• After the upgrading has completed, remove the Memory Stick. The system will restart automatically. If the
upgrading has finished successfully, the power LED will be blinking three times (0.3 sec ON, 0.3 sec OFF,
2 sec resting) whereas the Memory Stick access LED will be blinking slowly (0.8 sec ON, 1.5 sec OFF).
NOTE
The upgrading by means of the Memory Stick will only be successful if the main software is in good working
condition. If the upgrading process fails at some point, the main software will no longer work. In this case, it will be
necessary to disconnect the AC cable and to reconnect it while using a slim stick to press the forced power switch
S5301 accessible through a hole beneath the [AV MOUSE] connector.
