Why does my TV turn on and then off shortly after?
The most common reason for a TV to turn on and off is a problem with the power supply. In many cases, the power supply board that distributes power to different components of the TV may be malfunctioning. This can lead to insufficient power reaching the internal circuits, causing the TV to turn off after briefly powering on. If you notice the standby light flickering before the TV shuts off, it’s a strong indicator of power issues.
Another possibility could be related to overheating. Many modern TVs have safety features that automatically turn off the device if it detects high temperatures. If the ventilation is blocked or if there is excessive dust buildup inside, the TV can overheat, causing it to shut down. In such cases, ensure that your TV has enough space around it for airflow and clean any dust that may have accumulated.
Could a remote control issue cause my TV to turn off?
Yes, a malfunctioning remote control can inadvertently cause your TV to turn off. Irregularities such as stuck buttons or a low battery can send incorrect signals to your television.
