Question about Sony KP-57WS500 57" Rear Projection Television
COMES ON AND TURNS OFF AND THE TIMER LED BLINKS ABOUT 12 TIMES
TV's have a circuit that monitors the high voltage and shuts down the set if it senses something amiss.
On projection types, figure on just replacing the entire board that has the flyback transformer on it.
Hope ya fix it!

Tips for a great answer:
Five blinks - AKB
circuit (automatic kine bias), 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. In addition, unit could be in IK blanking, try turning
up screen A2 slightly.
