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

Post the video from YouTube Link so we don't have to download potentially sketchy files.

Hi,

I tried another TCON, but it didn't work.
I got a panel with TCON from my friend and was able to fix it with that.
