Standby light on Sony TVs blinks 16 times is abnormal I thiks. It may come up to 8 blinks or so. You jsut switch off the set by AC mains switch at the front panel, switch it again with it and count the exact numbers. Never switch it On_Off by remote hanset.
If it happens even after this process, you just do the following
Press the following button on your remote control as stated "Display"_"Channel"_"5"_"Vol Minus" [not plus] then "Power".
You may get "OVP" "OCP" "V STOP" etc displayed on the screen.
Just report the result to me through Fixya. Ok.
Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
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 slightly.
