Follow this procedure to troubleshoot a TV picture that is too dark. Refer to the manual provided with the TV if additional model-specific instructions are needed to perform any of the steps listed.
If Picture mode is set to Cinema or Custom, the screen may become dark. If the screen is still dark after the picture quality mode is changed, change the setting Backlight, Picture, Brightness and adjust the brightness to your taste.
Example of setting method: Check Picture Mode from Settings - Display - Picture and change the setting.
NOTE: When a TV is in a store they are set up for Shop Front display settings which are very bright and vivid. However, some Sony TVs may be shipped with more energy-friendly settings to comply with energy savings programs such as the Energy Star. Depending on such settings, the picture brightness level can be higher or lower.
If Power Saving is set to Low or High, the screen becomes dark.
Example of setting method: Select Settings - System Settings - Eco and set Power Saving to Normal or Off, and then check whether the problem is resolved.
Some TVs have Light Sensor feature; the picture will become brighter or lower depending on room lighting conditions.
Turning off the Light Sensor or Automatic Brightness Control (depends on your TV model) may increase picture brightness.
- View programming from a different source, such as a DVD player or VCR, to see if the issue is being caused by the device providing the signal to the TV.
NOTE: If the dark picture issue is displayed when viewing from one device only, the dark picture issue is being caused by that device, not the TV. Contact the device manufacturer for additional troubleshooting information.
- If it is a projection TV, consider replacing the lamp.
IMPORTANT: The method to replace the lamp differs by model. Refer to the instruction manual for model-specific steps to replace the lamp.
