    Thanks and you have been very helpful but I guess my inquiry wasn't fully disclosed but ater several hours the TV does come back on. This just keep reoccurring. This is full description of my issue( We turn it off and then teh next day the timer/standby light is blinking 10 times it blinks and when i do as instructed by Sony to reset it, it will blink 5 times but only the sound come in but not the video. If we wait until the next day the light has stopped and the TV comes back on(Video/Sound).

    Tmer light blinks in a ten blink sequence. Np picture or display of any kind. Is it possibly a power supply issue? Or perhaps could it be a lamp burntn out?

    STKs are big black ics which do control convergence as well as startup if one is bad set will not come on,also check little blue capacitor that is right behind hori output transistor 2kv 1200pf this also will kill high voltage. STK392-560 or 570s replace them both.If they are using 110s upgrade to 180s other wise use same replacement number on ics.

    Let me ck my code menu i have at shop i think maybe your high voltage trippler could be going bad. Also ck blue cap see if it might have small burt pin hole.

Sony TV


hello 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

Hi, 5 times blink of standby light shows that TV needs White Balance adjustment. No need to dump it, adjustment is also not so difficult. Let me know if you want to give it a try to guide you.

Sony Wega KDP-57WS655 Standby light blinks 9 times and wont turn


Service Manual of KDP-57WS655 says if TV standby light blinks 9 times then problem is Zero Corssing Detector and you need to replace diodes, D6116 or D6301 which are open on G Board.
