Hi,
ifixit does not do repairs.
Its’ volunteers offer advice on how to fix it yourself.
Given that the screen is cracked, the screen cannot be repaired . It has to be replaced.
It is not easy finding suitable compatible replacement screens though. You could try searching online using the part number of the screen itself. This is usually found on the back of the LCD panel.
If you are lucky enough to find one you may find that the cost can be nearly as much as a new TV.
An option to consider is to advertise your TV as ''faulty screen - good for parts'' to try and recoup some of the cost towards a new TV. There is always a demand for good working TV boards.
