What is tv turns on by itself at 3am?

As an AI language model, I do not have personal experiences, emotions, knowledge, or opinions, but here's some general information:

Having a TV turn on by itself at 3am could be a sign of a malfunctioning electronic device or power surge, where electrical signals trigger the TV to turn on randomly. It can also be a result of incorrect or unspecified settings or programming that are scheduling the TV to turn on at a specific time. Some people believe that paranormal activity, ghosts, or spirits can be the cause as they are believed to be more active during the witching hour (3am-4am). However, there is no scientific evidence to support this claim. It is advisable to troubleshoot the issue by checking the TV settings, unplugging the TV from the power supply and letting it rest for some time, or consulting a technician to diagnose and repair any defects.
