Because the KSZ80_OB_S4LV0.2 is vulnerable to thermal stress and component degradation, specific visual symptoms pinpoint exactly where the board is failing:

The PMIC generates critical voltages required by the liquid crystal display panel. When diagnostics are required, these test points are the first things a technician should measure: Because the KSZ80_OB_S4LV0
Requires an external, high-precision 12.1 kΩ (1%) resistor connected to ground to set internal bias currents accurately. Ksz80 Ob S4lv0.2 Datasheet
Component-level troubleshooting must be restricted to replacing individual surface-mount devices (SMDs)—such as ceramic capacitors, resistor networks, and PMIC chips—using a fine-tipped soldering iron or a micro-hot air rework station with targeted heat masking.
