Internal LCD eDP Cable
The eDP (embedded DisplayPort) cable is a micro-coaxial harness that bridges the system board to the LCD. Frequent hinge actuation can cause micro-fractures in the signal pairs, or the connector may slightly unseat, leading to intermittent synchronization loss that manifests as flickering or horizontal artifacts. Replacing the cable restores signal integrity and EMI shielding.

LCD Panel Assembly (14-inch)
If the flickering persists regardless of hinge position, the failure mode likely resides in the LCD's Timing Controller (T-Con) or the LED backlight driver circuit. These components are integrated into the panel and cannot be serviced individually. Failure in these circuits results in the inability to maintain a consistent refresh cycle, leading to visual strobing.

System Board (Motherboard)
The integrated GPU (iGPU) provides the video clock signal through the eDP interface on the motherboard. If the motherboard's power delivery phase for the display rail is unstable or the physical eDP port has cold solder joints, the signal will drop intermittently. This is the least likely but final hardware failure point in the signal chain.
