lg 55uh 770V vertical band

[bluettino]

Hi all.
I have a  lg 55uh 770V  with vertical band. No audio powering on. Backlight ok. I attach some a picture that show the problem.
There's a IC very hot, indicated by the screwdriver.
The voltages seem ok, 28 V vgh, vgl -5,x V. One of the COF connector feels very hot, but only the one indicated in the last photo.
Is there any possibility of repairing?

Thanks in advance for the help
