What if the screen is cracked

It had picture but now it has just sound I guess ill just replace the screen then
The tv with crackrd Screen Panel or broken the screen panel,will cost the same as a new tv to do a screen panel replacement.Because the tv screen panel is 90% important to the tv.Bcause u will not able to buy the tv screen panel anywhere else,only by the tvs corporations themselves,tvs screen panels are limitted produced and 90% important to the tv,it will cost to replaced as much as new tv,so tvs with damages or broken screen panels are only worth as salvages tvs for it good electronic boards for parts and uses for exchages for salvages sales for replacement electronic boards for other tvs only.
