How to Fix / Troubleshooting
Safety first: Disconnect power before accessing internal electronics.
Steps to improve display:
- Check ambient light: Confirm that the dimness is not just due to bright ambient light.
- Inspect connectors: Remove the front panel and reseat the connector between the display module and the main/UI PCB.
- Examine PCB: Look for heat discoloration or swollen capacitors in the low-voltage section of the main control PCB.
- Replace module: If the display remains dim or flickers, replace the display / UI assembly or the main control PCB depending on which contains the backlight driver in your Princess model.
