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.

    Sony KV-34HS510 blink codes


    I would question that diagnosis, Did you get it online somewhere or did you have a tech check your B+ voltages ?
    6 blinks is almost always caused by 2 chips on the "D board", they are both marked MCZ3001D you can order them here if you are a consumer not a tech 800-575-9833. Not to say that the jungle IC & those 2 caps couldn`t cause a dead set symptom but these 2 IC`s are notorious for the 6 blink code, I have personally fixed approx. 10 sony sets with the 6 blink code with those IC`s, hope this helps
