Power Supply Fluctuations

Solution: Ensure a stable power source by connecting the TV directly to a wall outlet. Inspect the power cord for any damage and replace it if necessary. Use a surge protector to safeguard against voltage spikes.
Overheating
Description: Excessive heat buildup inside the TV can trigger an automatic shutdown. Prolonged usage, poor ventilation, or dust accumulation can contribute to overheating.
Solution: Allow the TV to cool down by unplugging it for a few hours. Ensure adequate ventilation by placing the TV in a well-ventilated area and avoiding covering the vents. Clean the TV regularly to remove dust and debris.
Software Bugs
