T-CON (Timing Controller) Board

Internal LVDS Ribbon Cable Set
These ribbons connect the Main Board to the T-CON board. Oxidation on the pins or a loose connection due to thermal expansion can cause data loss, resulting in vertical lines. Reseating or replacing these cables is a common low-cost fix if the T-CON itself is functional.
