Are the Power Timer and Sleep Timer on LG Smart TV the Same?
No. Both the options are completely different. Sleep Timer lets you set a specific time. After the time you have set, the TV will automatically turn off. For example, if you have set the sleep timer to 1 hour. After 1 hour, the TV will turn off.
On the other hand, Power Timer lets you set the time for the TV to turn on or off every day. For example, If you have set the Power On Timer option to 7:00 AM and the Power Off Timer option to 10:00 PM, the LG TV will automatically turn on at 7:00 AM every day and turn off automatically at 10:00 PM.
