Replacement LCD/LED Panel Assembly
Horizontal lines indicate a catastrophic failure of the row-gate drivers or the electrical traces within the TFT (Thin Film Transistor) matrix of the panel. These drivers are bonded directly to the glass substrate and cannot be individualy replaced or resoldered. Replacing the entire panel assembly is the only method to restore the integrity of the row-addressing signals.

T-CON (Timing Controller) Board
While horizontal lines are usually panel-internal, a malfunctioning Timing Controller board can occasionally cause synchronization errors across the entire horizontal refresh cycle. This is less likely if the lines are static and distinct, but a failure in the T-CON's voltage gamma IC can produce similar artifacts.

Main Logic Board
A faulty System-on-Chip (SoC) on the main board may incorrectly process LVDS (Low-Voltage Differential Signaling) data before it reaches the display boards. If the horizontal lines are intermittent or change behavior when navigating smart apps vs. HDMI inputs, the processing logic may be the point of failure.
