Sony Bravia showing 4 red blinks any idea what this means, fault?


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/

Sony bravia kdl55hx729 3d led tv turns on 3 seconds shows picture than four red flashes


Hello,
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!

My bravia will not stay on.


Hi,
If Bravia tv wont stay On and shuts Off itself that means it got some internal problem, you will see red light flashing on tv front in specific blinking time that is an error code, let me know how many times that red light is blinking after three seconds long pause to diagnose problem.
Thanks.

I have a SONY KDL-40S2400. When I turn on the tv it will turn on for about three seconds then turn off. After it turns off the standby light (red) will flash four times.


ITS A BACKLIGHT PROLEM BACKLIGHTS ARE DRIVEN BY A INVERTOR BOARD THAT NEEDS REPLACING OR CAN BE REPAIRED SO BEST IS TO CONTACT SONY SERVICE CENTRE OR IF U WANT TO REPAIR ITSELF LET ME KNOW I GIVE U THE PART NO.

Four blinking red lights.


Either on of the backlight inverter boards is bad or a backlight has failed inside the panel.
