How to Fix / Troubleshooting
Safety first: Unplug the unit before removing the control panel.
Steps to restore button function:
- Clean the panel: Wipe the control surface with a soft, dry cloth. Avoid excessive moisture or harsh cleaners.
- Dry out moisture: If the panel was exposed to steam or spills, leave the unit unplugged in a dry area for 24 hours.
- Inspect ribbon cable: Remove the bezel and check the ribbon cable between the touch panel and main PCB. Reseat it carefully and ensure no kinks or cracks.
- Replace UI board: If specific buttons never respond while others do, the touch membrane or UI board may be defective and should be replaced with an LG-compatible part.
Note: Avoid pressing the panel with sharp objects, which can damage the touch surface.
