Need help, what's broken in the panel?

Question

LG

There are two LG panels in the hall, and so the workers did the repairs, and after the repair, one panel, when turned on, does not show anything, only a dark background and lines of artifacts are visible (attached a photo), and the second is normal, who knows what specifically broke down in the TV set and whether it is subject to repair,
perhaps not very noticeable in the pictures, but there are stripes, and this is not the case with the cable, but with the TV set,

but it should be when you turn on such a picture

Answer 1

I think there was a destruction of the canonical jumpers in the ninth rotor. It can be fixed, but it needs to be sent in for repair.
