Question Vertical Lines on LED screen

[angustiatulao]

I recently bought a TV less than a month ago and now it has 2 vertical dead line on screen. I called the service center and they came to my house after 3 days. After they inspect the TV, they said that there are ants in the tv and there's no way to fix the unit. Is it true? I have Devant 43UHD201. Thanks.

EDIT: As per the technician there are ants in the flex wire. Is it impossible to fix?

You could try an independent repair centre? unless the screen itself is damaged there ought to be a way to fix it.
