Good fixes. Sometimes the connector for the cables running from the LCD to the T-CON do not make good contact. You might try moving them around to see if it affects the picture. You can even carefully disconnect and reconnect them.
I have come across one person that fixed a display by resoldering as many joints as possible on the main board.
When these boards are made they use a wave solderer and with the new RoHs standards and shoddy workmanship a lot of 'cold joints' are developing. If you do this, use RoHs compliant solder.
