If audio is OK, the fault should be with its backplight inverter baord. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Viewing it in "

G'Day!
Unfortunately, what you're describing is a repair
issue. You won't be able to address the problem with troubleshooting.
There is a part inside the TV that needs to be replaced. If you're
under warranty, this will cost you nothing. If you're not under
warranty the cost will likely be a minimum of $200 parts and labor.
However, be warned that the cost could be considerably higher.
