tha't an easy task to handle
See the pictures below
if your whole screen shows an image and the cracks are in front of it then its just a cracked digitiser
if you dont see the whole image and tyou see horizontal and vertical line or an image like spilled liquid then your Lcd is also cracked too


this is a broken Lcd (the screen is distorted by the lines or no picture at all)


this is just a broken digitiser (the screen below the broken glass works fine )

hope that was helpful

You have to take it into a shop and the cost will be more than a new set. You cannot buy a screen that big and install it yourself.

If the set got struck on the screen the screen itself may not be cracked but the panel (The entire front where you view the image is called a display panel) may be damaged inside.

A good photo would tell me--usually it will look like a odd burst or lines and or colors more pronounced where the screen was hit and spreading out in a uneven pattern---Google for "Pictures of Damaged LCD or Plasma screens"

If there is picture in the TV then probably it is the protective screen that has cracked and not the picture tube.Please check carefully.

Can you please post the picture or video of the fault?

Yes, thats correct.
If lcd tv screen got hit by some thing then lcd panel got cracked and does show distorted lines or cracks instead of picture and lcd panel have to be replaced that would cost you 70% to 80% of new tv price.
New TV is better option.

If the main PCB is not cracked too bad, it should not be expensive to repair. You have lost vertical deflection causing the flat line.There may be a crack at the flyback, where the vertical IC gets its operating voltage, or a crack at the pins of the vertical IC itself.

your screen has a small crack inside, but the screen is not used to take your pictures, so the pictures turn out fine.

Yes lcd screen is cracked. No way to repair, other than changing screen. Cheaper to buy new tv.
