Why Does My TV Come On Then Go Off?
If you want to fix your TV that keeps turning on and off, you need to know the potential causes of the problem. Here are the most common ones:
Power supply issues: Loose connections can cause your TV to shut off unexpectedly. The cord should be securely plugged into the wall. Otherwise, your TV may refuse to work or turn on and off. An aging power supply cord can cause similar issues.
Connected devices issues: Since technology doesn’t last forever, your TV can start turning on and off if you use outdated devices like old DVD players or cable boxes. This often happens when the connected devices send “wake-up” signals to the television without your intervention.
Remote control issues: A remote that’s running low on battery can also send errant signals and cause this.
Hardware problems: Hardware issues could be the culprit if your TV turned off suddenly with no visible issues. In most cases, the problem starts with the motherboard. If this critical component of your TV is damaged or worn out, it will likely overheat. Modern TVs can detect the heat and shut off to prevent further damage.
Power timer enabled: Modern TVs come with power times that let you turn the television on and off at specific times.
