These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

SOURCE: Sony Vega Service Codes

KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.

There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.

If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.

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.

Wont turn on blinks 7 times

Hi there.
In sony tv`s the seven blinks code(sony error codes)usually indicates a high voltage shutdown(t.v has exceeded 33k volts). That is often caused by the power supply regulation and/or horizontal circuit fault.
Hope this help Merry Christmas

    SONY KV32-FQ70U BLINK ERROR

    Try unplugging the TV for about 10 minutes and then tunung it on again. Try a factory

    To reset the TV to factory settings
    1
    Turn the TV on.
    2 Hold down on the remote control.
    3 Press and release the POWER button on the TV front panel. The TV will turn itself off,
    then back on.
    4 Release .

    I'm assuming step 2 means hold down the power button.
