    I did say that the settings do not make a difference.... i could set the light timeout and power saver timeout to the max, my phone's light still stays on for not more than 5 secs.

Vizio smart tv, model E550i-A0, I have a dark screen and cannot adjust brighter.


Hello.
Have you looked at the Vizio Manual? Page 23 has a few features that may need looking over.
  • "Smart Dimming- Improves the contrast ratio of the screen by adjusting the backlight intelligently. Select On or Off.
Smart Dimming may need to be set to off in order to adjust the brightness.

Here are a few more.
  • "Adaptive Luma" - Adjusts the average brightness of the picture to compensate for large areas of brightness. Select Off, Low, Medium, Strong, or Extend.
  • "Ambient Light Sensor" - The ambient light sensor detects the light levels in the room and automatically adjusts the backlight for the best picture. Select Off, Low, Medium, or High.

Samsung TV backlight is very dim on LN40B530P7N Television


Check if the sensor of the ambient light in the room is dirty (bottom of TV). If so, the TV thinks its playing in a dark room and so sets the screen to dim.

If that doesn't improve things, turn a flashlight on the sensor to fool it into thinking its a brighter room.

2006 grand Prix the drl stay on and will not go off if they do go off the come back on with nobody around the car keeps running the battery dead ????? Ready to burn it


Daytime Running Lamps (DRL)
The ambient light sensor is used to monitor outside lighting conditions. The ambient light sensor provides a voltage signal that will vary between 0.2 and 4.9 volts depending on outside lighting conditions. The body control module (BCM) provides a 5-volt reference signal to the ambient light sensor. The ambient light sensor is permanently grounded at ground G202. The body control module (BCM) monitors the ambient light sensor signal circuit to determine if outside lighting conditions are correct for either daytime running lights (DRL) or automatic lamp control (ALC) when the headlamp switch is in the AUTO position. In daylight conditions the BCM will command the low beam headlamps ON at reduced intensityy. Any function or condition that turns on the headlamps will cancel DRL operation.
There could be a DTC stored in the BCM pointing to a problem !
DTC B2645 Ambient Light Circuit

Turn the headlamp switch to the OFF position.
Do the low and high beam headlamps remain OFF?
Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
Go to Step 3

3

Remove the appropriate low or high relay.
Do the lamps turn OFF?
Go to Step 5

My phone vibrate automatically and display fades automcatically t


Hi,

If you want to stop the Vibration then press and hold the # kep for about 7 seconds, this automatically makes your phone silent. for the fading display you'll need to go to the display setting and set the backlight to stay longer say 1 minute before fading off.

Hope this helped.

My acer aspire 9300 screen is very dim and I cant seem to get it brighter . I can barely see the icons?


Try resetting the laptop to default settings in the BIOS. If that don't work, sounds like there's a problem with the backlight in the LCD Display.
Most laptops come with Ambient Light Sensors, that can adjust the display based on the lighting in the room.

No backlight


A couple things to try:

1st check the backlight settings

Turn on Backlighting and Control Brightness To use your device in dark environments, enable the automatic backlighting feature:
  1. From the Jump screen, press MENU t02003-15.gif then select Settings > Battery & Display.

  2. In the second group box, select the Turn on backlight when using device check box.

  3. Highlight, then select the Brightness slider to open it for editing. Roll the TRACKBALL right to increase brightness; roll the TRACKBALL left to decrease brightness. After you've made the adjustment, press the TRACKBALL to exit edit mode. t02007-55.jpg

  4. Select the length of time you want backlighting to stay on from the Turn off after pop-up menu.

  5. To use the device's light meter while the backlight is on, select the Use ambient light sensor check box.

  6. Press JUMP t02003-14.gif to return to the Jump screen and save your setting.
Now, when you press any button or key, or flip open the screen, backlighting will turn on for the set amount of time. Note that as long as you press a key or button before the set time elapses, the backlight will stay on.
Tips:
  • Even if you have not selected automatic backlighting, you can turn on backlighting at any time by pressing MENU t02003-15.gif + JUMP t02003-14.gif . The backlight will remain on for the time specified in the Backlight Turn off after pop-up menu.

  • When in key guard mode, you can turn on the backlight by pressing the RIGHT SHOULDER t02003-66.gif button.
If it still does not work, then you can try resetting the flex cable to the lcd.

Reseat the SidekickFlex cable

If that doesn't fix it then a new lcd assy will take care of the issue. they run about 45 dollars on ebay.

Have you tried checking the Battery and Display settings from the main screen Settings menu? There is an option to enable or disable the backlight, as well as set the brightness.

There is also a setting called "Use ambient light sensor", which sets the backlight and keyboard light to only turn on if it is dark when you are using it.

Backlight of LCD turns off


Hi,
For latitude systems they have this ambient light sensor. it basically adjusts the brightness of the screen depening on room lighting. try to go to bios by hitting F2 on the dell logo. go to video and try to look for ambient light sensor. however, im not sure if your computer has that feature I have a second option for you though. based on the troubleshooting you've done, it seems that the video back lighting is affected by movement. it would be a good try to reseat the LCD cable. you can use this link to guide you in fixing the computer : http://support.dell.com/support/edocs/systems/latd505/sm/keyboard.htm
all you need to do is to take out the keyboard with 2 screw holding it in place. the LCD cable should then be accessible. it a thick cable that coming out of the Left hinge.

Hope this helps.

thanks.
