Bravia KDL46EX720. Red LED blinks 4 times and TV wont turn on. What is the problem?

I tried unplugging the power. Afterwards the TV would turn on for a few seconds but then turn back off, and then the red blinking light would resume blinking 4 times and then pausing and then blinking 4 times again repeatedly. I tried googling what that error code means. I could not find anything about that exact model number but on an older sony tv it meant there was a fan issue. Can anyone tell me what that error code signifies and how I may be able to fix it.

Hello Scott,

Welcome to the Sony Community Forums.

4X Blink – Balancer Error
The 4X error code is only used on models incorporating local dimming LED backlighting. If a failure occurs on the LD board the TV will shut down and display this diagnostic code.

Please contact Consumer Electronics support for repair options.

Hi jpernia!

 
Thanks for the message. Follow the steps below to troubleshoot the TV. 
 
Do a Power Reset.
 
1. Turn off the TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.
 
If the issue still persists after performing power reset, that may be an indication that the TV needs service. You may refer to this link to locate the nearest Sony authorized service center in your area.
