SOURCE: Acer Aspire 5735 LCD changes bight-dim-bright, etc.

You could have a faulty inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

NEED TO ADJUST BRIGHTNESS


You didn't post the Make, Model of Laptop or the OS? All I can suggest is to Open the Control Panel, select Power Options, set to High performance, Change Plan settings, adjust brightness or when to dim display. If you are on Battery power the displat will dim to conserve battery power. Plugging in will brighten the display. If you have a NVidia Graphics Adapter it can be a bit different. Do ALL your Windows and Laptop Manufacturer's updates.

Acer aspire 3000 display dim can i make it brighter?


You should be able to adjust the screen brightness using the "FN" key and the keys that have a sun on them with a arrow up and down. Or you can right click on the desktop and change the screen's brightness in the display properties. And sometimes laptops are set up to automatically lower the brightness when the power properties are set to power saver...like when running on batteries only and no ac power connected.

Backlight only stays on for a few seconds on compaq c700 that is only a year old


When the external AC power supply is unplugged from a notebook, the LCD display will dim to conserve on battery power. During times of heavy battery power operation; such as during the startup or boot process, the display may be very dim or barely readable. If the display remains dim when the notebook is operating on the Windows desktop, follow the steps below to resolve problems with display brightness Restart the notebook with AC power Follow the steps below to determine if the dim display is due to a hardware failure:
  1. Connect the AC adapter to the notebook and a working electrical outlet.
  2. Power down the notebook PC by pressing and holding the power button for 5 seconds.
  3. Press the power button again to start the computer.
If the display is still dim after restarting with the AC adapter connected, try changing the LCD brightness. Adjust the LCD brightness using the function keys From the Windows desktop, hold the fn key and press the f7 key c00776226.jpg to increase or the f8 key c00776225.jpg to decrease the brightness of the display. If using the function keys does not resolve the problem and you have a Lid Actuator on your particular model, check the movement of the Lid Actuator switch to determine that it moves freely and is not stuck. NOTE: The key numbers ( f7 or f8 ) may vary depending on the notebook PC; however, the images on the keys should be familiar. Check the movement of the Lid Actuator switch The Lid Actuator switch is available on some models. It is a small button or switch located above the keyboard near the hinge for the LCD. Pressing this switch when the computer is on may turn the notebook display off, or it may cause the notebook to enter a different power state. Press the switch two to three times while observing the display. If the display does not return to normal brightness when the switch is released, the switch may be sticking and need to be repaired. Contact HP service and support for further assistance. If the display turns off when the switch is pressed, the power management function may be set to hibernate or turn off when the lid is closed. Install updated BIOS and drivers To resolve certain hardware and software issues, use HP Health Check to automatically search the HP web site for an updated BIOS as well as any updated software and drivers. To launch HP Health Check, follow the steps below.
  1. Click Start , type health into the search field, and then select HP Health Check from the list. HP Health Check displays a list of available BIOS, software, and driver updates for your particular model.
  2. Click the description link for any BIOS, software, or driver updates, and then follow the on-screen instructions. You can only install one update at a time.
  3. Repeat steps 1 and 2 above for all updates that you want to install.
You have now installed the available BIOS, software, and driver updates for your particular computer model. Contact HP service and support If the display remains dim after doing the troubleshooting steps listed in this document, contact HP service and support for further assistance.

Acer aspire 5043wlmi laptop starts but know function of lcd but works on desktop monitor


The computer's power management system automatically dims the screen when using battery power, which is one of the power-saving features.
To adjust the brightness:
  • Hold down the Fn Key located at bottom left of your keyboard next to the Ctrl key, and adjust the screen brightness using the left/right arrow keys located at the bottom right of the keyboard.
If that's not it then

A dim or dark screen does not necessarily mean a bad inverter! It could be a faulty lcd backlight bulb, inverter cable, inverter, or in some cases a motherboard failure. If your still under warranty then I would get Acer support on the phone and see what they can do.
An Inverter converts direct current (DC) to alternating current (AC).

Wave Radio-dial face,display very dim.


Our Bose did the same thing after a power outage. This one doesn't have a CD button, so we tried holding down the Clock button and used the volume control and that seems to have fixed it.
