This is a common failure with this set, it is in the power supply, switch mode regulators in the ps need replaced, the repair would be typically cost around 200 - 250 from a shop to repair. if you want to fix it yourself i can get the part numbers just post back and let me know if you are a do-it-yourself er.

Pressed power, heard the unit turn on, heard the tv show sound for a moment then it went into standby mode and the red light flashes six times, then pauses, six times then pauses, over and over and over. ...


Either your power supply is bad and needs replaced, or their is other circuitry issues. Bets to have a trained technician look at this and give you a quote for repair, it might be cheaper in the long run to replace the set.

Sony Wega KV-34HS510 standby blinks 7 times in red


Hi and welcome to the site,

Initially, the Sony KV-34HS510 uses the DA-4 Chassis. On this chassis, 7 blinks refers to the fault "Horizontal Deflection Stopped" indicating a problem with the horizontal section. Offhand, check, replace the HOut transistor and have the FBT (flyback transformer) ring tested.

Good luck and thank you for asking.
