Remove the cover of the TV and find the ribbon wire that supplies the LCD of your screen. Clean it with a contact cleaner for possible lose contact. Then try to turn on the TV. Most cases lost contact is the cause of that line.

After checking for possible lose contact but the problem still appear, that is more likely the T-CON Board was partially defective. You can replace the t-con board whole assembly. That is available now in the market.
