FIVE Blinks---AKB circuit (AKB), the timer/standby indicator blinks for about
30 seconds then goes to the self-diagnosis function. Something is wrong with
the video. Check video out, Q705, 732, 761 and other components on the C
board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking,
try turning up screen slightly.

SONY KP-57HW40 TUNS OFF AND STANDBY LIGHT BLINKS 6 TIMES


6 blinks is usually associated with failure of the horizontal deflection amplifier - which shuts down the high voltage system as well.

The repair requires testing to determine the exact parts that have failed. There are, for example, a few hundred parts and a section of the Jungle IC chip involved. So, repairs could require something as simple as replacing some inexpensive passive components OR as complicated as replacing the jungle chip (very expensive).

most of the time it's the horz. transformer and transistor.
