2 Tv`s 1 , 4k with remotes 65", 42" never opened

These 2 tv`s were never opened they are in the same condition when bought new. we were going to have someone fix them but just got new tv`s instead. when powered on the logos flash for about 1 or 2 seconds, the tv`s stay powered on but have dark screens. found out all they need is the back lights fixed. Toshiba 65" , $90 and Sharp 42". $30, see pics for the model numbers. we have the remotes for both Tvs. screens are all in great shape no cracks tv`s were hardly used,
