Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some newer models of Sony TV sets, this code means that T8005 is defective on the D board. If your not a tech and have no solid state repair experience, play it safe and call out a pro to assist you in this type of repair.

hello ,Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. 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.

6 bliks on sony kp-46wt510


KP46WT510 Shutdown 6 Blinks. 6 Blinks = Low B+ OCP/OVP
SOLUTION: Replaced Flyback transformer. It had no rings on the ringer test.
HQ
Comments: Any load on the B+ line can cause 6 Blinks.
Example: If the 200v line is loaded down will cause a drop in B+ due to bright picture current demand.
