Sony KD-55AG9 TCON?

[bbrain]

Hi,

I have this problem with my Sony 55' AG9.
It flashes 4x.
I have found the service manual, and seems it is the TCON.

Before I buy a TCON can someone check the vid?

open it and post photos tp all boards separately and one to the whole back together

on the T-CON you have EVDD >22V,,, just disconnect it and see if the tv will complete boot ( screen will remain black) yours sign TV booted and work the audio optic port on main boards will lit red color and remain on
