May not be a do it yourself repair, could be main board or even a loose connection at a plug inside the display panel (fatal) or outside of it.

The horizontal lines on the screen are virtually NEVER caused by a bad T-con board. These horizontal lines indicate a defective LCD panel (screen). The Screen has small ICs that become defective overtime and that it isn't fixable unless replacing the entire screen.
