Corner of the screen was hit with something and now where it was hit t

Hi @quinnfrost

If you mean that there's no image on the screen in the area where the corner has been damaged, then the screen will have to be replaced as it cannot be repaired.

Disconnect the power to the TV and then remove the back cover and check if you can locate the make and model number of the LCD panel. This will be different to the TV model information because TV LED panels are made to order by specialist screen manufacturers and not the TV maker themselves (except perhaps, Sharp, Samsung, Toshiba and LG who do make their own).

If you find the information, search online using that information to hopefully find suppliers of the screen.

Be aware that a replacement TV screen can cost nearly half as much as a new TV so perhaps a better option is to advertise the TV as TCL ( insert full model number) faulty screen, good for parts, to try and recoup some of the cost towards a new TV. Working TV boards are always in demand.

If you can't find a replacement screen you may just have to live with it as it is.
