Important notice for LG TV issues

If the problem persists after troubleshooting, disconnect the TV from power and contact a qualified LG technician or LG support for further assistance. Avoid repeated use if hardware failure is suspected.

Important: If the issue persists after troubleshooting, disconnect the LG TV from the power source and allow it to rest for a few minutes before attempting another restart. Continued operation while recurring errors, display issues, sound failure, or system instability are present may lead to further damage to internal components such as the power board, main board, backlight system, or software firmware. If the problem continues after a reset or power cycle, do not repeatedly force restart the television, as this may worsen the condition. Instead, stop using the device and ensure all external devices such as HDMI cables, gaming consoles, or streaming devices are disconnected before further testing. For safety and proper diagnosis, contact an authorized LG Television technician or LG support center for a full inspection. Professional servicing is recommended especially when the issue involves power failure, no display, repeated boot loops, overheating, or persistent error codes, as these may require internal component replacement or advanced repair procedures.
