Hi

This error means that one of the fans is NOT spinning! To check.... unplug the tv.... turn the TV around to a well lighted area so that you can see the fans in the back... plug the TV in and turn it on. Watch for the fans in the back... and see if they are spinning. If not... that is the reason why the TV will not turn on! It could be the fan next to the lamp was stuck for some reason. Remove the cover of the TV from the back... and clean the fan, also make sure all connectors to it are properly connected.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks

    Hi



    If the fan is perfectly fine then this is happening because 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.



    After you repair the unit, you MUST clear the values on this diagnostic screen. These codes do not reset themselves after the fault is corrected, so if you don't clear them, you'll be seeing "old" fault codes the next time you enter this screen. Clearing is done by going into the service mode (display, channel, 5, volume plus, then power ). Press 8 and Enter, which returns everything to the factory preset condition.



    Please do accept the solution if the issue is resolved or else revert for further assistance.

    Thanks

Hello
Five consicutive blinks at a time and the stops and again blinks five; is its self diagonosis procedure. All modern Sony sets has this function included in its circuits. If the system control IC inside it detect any fatal fault inside its circuits system, it will give a signal to its power control unit to shut it down its high voltage outputs to protect the other components from further damage. In your set; as Sony describes; I quotes:-
  • 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.

  • Actually the components marked in numberes will not be the same as in your TV. But the fault will it be.
    If you have enough knoledge in electronics and have a concept of soldering and have a good quality multimeter; youreself can do this work by home. OK

    That means the tube is getting weak and a tweak of the A1 control could help.
