(When letters/numbers appear in the 
display)
When the self-diagnosis function is activated to 
prevent the system from malfunctioning, a 
5-character service number (e.g. C 13 50) with a 
combination of a letter and 4 digits appears on 
the TV screen and the front panel display. In this 
case, check the following table.
When displaying the version number on the 
TV screen
When you turn on the system, the version 
number [VER.X.XX] (X is a number) may 
appear on the TV screen. Although this is not a 
malfunction and for Sony service use only, 
normal system operation will not be possible. 
Turn off the system, and then turn on the system 
again to operate.
