Can you fix my Roku TCL television?

Description

I have a Roku TCL 55" t.v. that has a black screen. I have tried the "Home x5, Up x1, Rewind x2, Fast Forward x2" code/fix a bunch of times (see link below), but after doing this fix for a while, the screen stayed black. So I need the tv repaired. Can you fix my tv, or do you know someone who can? How much will this cost? I don't need another code, I need the tv fixed. Please respond with contact info. Thanks! https://www.youtube.com/watch?v=zefoPrUklN8&ab_channel=WorldofTech
