Turn up your brightness if you can. If you can't and there is still no backlight, you may have a blown inverter board or dead backlight. It may be covered if you are under AppleCare.

VX37L Screen Suddenly Went Blank, Now No Image, Sound Only on Cable Input, VIZIO Logo Lights Up


Hello,
turn on the set, grab a bright flash light and dim the lights in the room. Shine the flash light on the screen, if you see a faint picture on the screen, you are dealing with a backlight problem. There are several things that can cause this. One, a bad backlight inverter, two, faulty 24vdc power supply, three, bad main board, or a bad faulty backlamp.

The screen light on my phone doesnt work


More than likely, you've turned the back light off all together. Go into the menu, and display settings and find the backlight options.

If it's set to 'on' and to stay on for at least 3 seconds, yet nothing works: turn your phone off and then back on again. If still nothing, take the battery out, put it back in and start it up again.

If there's still no backlight, contact your supplier or the store you bought it from.

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.

Because your screen is broken and that can only be fixed if you have it replaced.

Sidkeick 3 backlight


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.
