KDL-46HX800 blinking 4 times wont turn on
I hope you can help me. I am a newbie in the TV repair area, I have a SONY Bravia KDL-46HX800 which it is in standby and when I want to turn on, the lights turns green and after 2 seconds it turns red and blinks 4 times.
I have been googling it and I could dissassemble and make sure it has 3.3v in the stand by pin. I would like to identify which board (Power Supply, main board or led driver) is the defective one so I can order a replacement.
These are some photos of the power board:
Thank you very much.
