Question:

Why is my TV's brightness changing automatically?

Answer:

Subject:  The Brightness Is Dimming Or Flickering Automatically

If the brightness on your TV changes automatically (randomly dims and brightens), you may have the Energy Saving function set to Auto.

The Energy Saving function adjusts the brightness of the TV to reduce power consumption.

When you set the Energy Saving function to Auto, the TV changes its brightness automatically depending on what you are watching on the TV.

These changes in brightness can look like flickering.

To correct this problem, change the setting of the Energy Saving function to Off, Low, Medium, or High.

To change the setting for Energy Saving, follow these steps:

1. Press the MENU button.

2. Use the up or down arrow to select 'Setup',and then press ENTER.

3. Use the up or down arrow to select 'Energy Saving', and then press ENTER.
4. Use the up or down arrow to select any setting other than 'Auto', and then press ENTER.

  

Press the EXIT button to leave the main menu.

If the flickering continues after setting the Energy Saver setting from Auto, test the TV on a different source.

The flickering may be caused by the external device or the cabling connecting it to the TV.
