Quick Answer
Pool control panel display problems range from simple brightness adjustments to failed LCD screens. Start by checking brightness settings and viewing angle - many displays have auto-dimming features. Look for backlight glow in dark conditions to confirm power. Check for protective plastic film on new installations. If the display is completely dark with no backlight, you likely have a power supply or display failure requiring professional repair. Touchscreen issues often indicate digitizer damage from excessive pressure or age.
