Massive TV Spares or Repair (Newcastle-under-Lyme CW3)

This huge TV I think is an LED screen. My 7 month old baby silverback gorilla of a grandson hit it with the remote and the screen is doing some strange things. The TV repair shop said they couldn’t fix it but they didn’t see it.
Maybe someone here might like to try?
I don’t have the remote.
I might be able to deliver for the cost of the fuel.
