The TV may not turn on if there is a power issue. The following situations may cause a power issue:
- A drop in voltage in electrical power
- Power fluctuations, such as brownouts or blackouts.
- A storm
If a power issue hasn't occurred, it's possible that the batteries in the remote control are weak or that something is interfering with the infrared (IR) signal to the TV.
NOTE: For model specific information regarding any of the steps in this solution, refer to the supplied operations manual. Manuals are posted on your model support page.
- If the Red, Green, or Orange lights are on or blinking on the TV, a separate article is available to troubleshoot the issue.
Make sure the AC power cord (mains lead) is connected securely to a working wall outlet. If the power cord on the TV is removable, make sure that the power cord is securely connected to the back of the TV.
NOTE: If the TV is plugged into a power strip or surge protector, unplug it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
Make sure that the power cord is securely connected to the back of the TV.
