How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before accessing the control panel.
- Check brightness settings: Some LG Studio models allow display brightness adjustment in the settings menu; increase brightness if set low.
- Inspect connectors: Remove the control panel and reseat the display connector on the PCB.
- Look for heat damage: If the display area of the PCB shows discoloration or bulging capacitors, replace the main PCB or display module as applicable.
- Replace display assembly: If the display itself is failing, install a new display/control assembly matched to your model.
Note: Display issues are usually progressive; early replacement can prevent complete failure.
