Most likely your Y Sustain panel has gone bad. I would have a qualified service center evaluate it to be sure.

SOURCE: My Samsung 42 inch plasma TV is cracked, do you

all you can do is

Google the make and model of your TV followed by Replacement screen
you will only get it off the internet, no local shop or supplier will have one

If your tv is under warranty get it repaired / replaced

otherwise you can do it yourself

its relatively simple to do
