Question about Televison & Video
A 4 flash shutdown is a vertical stop condition, meaning that the vertical deflection circuit is shutting down.You need to purchase the service manual from :-
Once you have the manual, check the plus and minus 15 volt supplies on the G board. They are fused and the fuses are the easiest place to check them. If the fuses are blown, I would be thinking a bad convergence IC, as that is a common failure on these sets.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

Tips for a great answer:
On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.
