Troubleshooting
If the TV seems to have a problem, first review this list of possible problems and solutions. Also, review the Troubleshooting Section in the
Issues | Solutions and Explanations |
|
|
Flickering and Dimming | Try disabling some of the TV's energy efficiency features. |
| Disable Energy Saving (System > Eco Solution > Eco Sensor) and/or Energy |
| Saving (System > Eco Solution > Energy Saving) and check again. |
|
|
Screen Color is Not Correct | Run a Self Diagnosis Picture Test (Support > Self Diagnosis > Picture Test). |
| If the picture problem is caused by the TV, the problem should be visible |
| in the Picture Test. If the problem is not visible, next confirm that the TV's |
| video input ports are connected to the correct external video device output |
| ports and that none of the connections are loose. Finally, if possible, test |
| your external video devices by connecting them to another TV. |
|
|
Screen Brightness | Adjust the following settings: |
| Navigate to Picture and adjust Backlight, Contrast, Brightness, Sharpness, |
| Color, Tint (G/R) and other picture quality adjustment settings. |
|
|
Blurred Images | Turn on Auto Motion Plus (Picture > Picture Options > Auto Motion Plus). |
|
|
Unwanted Powering Off | Check if Sleep Timer (System > Time > Sleep Timer) has been enabled. |
| Sleep Timer automatically turns off the TV after an amount of time that |
| you select. If the Sleep Timer has not been enabled, see if No Signal Power |
| Off (System > Eco Solution > No Signal Power Off) or Auto Power Off |
| (System > Eco Solution > Auto Power Off) has been enabled. No Signal |
| Power Off turns off the TV if no signal has been received by the TV for a |
| specified period time. Auto Power Off turns off the TV if there has been no |
| user input in four hours. |
|
|
Trouble Powering On | Confirm that the power cord is connected and that the remote has live |
| batteries and is functioning correctly. If the power cord is connected |
| properly and the remote control is operating normally, there might be |
| a problem with the antenna cable connection or the cable/satellite box |
| might not be turned on. Check the antenna connection or turn on the |
| cable/satellite box. |
