Over time your blue CRT in the back of your set develops a fungal growth that covers up the glass and prevents light from shining through clean this off with a cloth dampend with waterd down bleach. While you're in the back of the set clean all 3 of the tubes of with this solution. After that wipe the back of the screen off with a dry cloth. Wipe the delfection screen of as well this is the screen that is diagonal to your front screen it actually deflects light to the back of the screen you watch. These can become very dusty over time and block light. This should fix your problem. If it doesn't the fluid in your 3 cathode ray tubes is cloudy and will have to be changed by a tech.

Dim screen acer 5100-3019

Try going into power option settings and taking the brightness to the max there. Start, control panel, power options, then you should see a setting for battery and for plugin. Hope this helps.

Monitor dims when we turn lights off in room.

You need to give a more detailed description of the problem.
The LG 47LH90 is an LED backlit TV with 'local dimming' technology. This means that there are lots of white LEDs behind the screen and these can be controlled in groups to allow localised areas of the screen to be dimmed to produce better contrast between light and dark. It is very likely that when the room is dark, this local dimming is more noticeable. The actual individual LEDs cannot be controlled and so the area that is dimmed will generally be greater than the area that is required to be dark 'blooming effect'. In addition, LED backlit displays only maintain their contrast through a tight viewing angle. If you sit too farto the right or left, then light from non-dimmed LEDs will leak through and the screen will look lighter.
In short, there may not be any fault with your TV.

My Vizio LCD TV screen fades to dark. Sound stays on.

I w having this same issue when watching a Blu-Ray disc. I found it to be dependent upon what picture mode the TV was set to. By this I mean certain picture modes would cause the TV to dim during dark scenes of a movie. Changing the picture mode helped a lot.

The Tv sounds like it has a fault. Firstly, switch tv on in a dark room and look through the back cover grills at the tube neck. If it is lit up a dim orange, the heater is ok, and the problem is either a loss of voltage to the tubes first anode (A1) or a field collapse problem ( a line across a black screen which is blanked out by the tv protection circuitry) could be a black level clamping fault on the video driver chip or faulty video driver chip.

Our sony tv has a standby button that keeps flashing and we can't get the tv to come on, it sounds like it comes on but the screen is black. Is there something specific on the remote we need to push to get...

does the tv give a pulsing sound to the same rthyum as the flashing standby LED? If not, when you switch on the TV, you should feel static on your hand when touching the screen on switch on. Also, if you look through the back cover in the dark, you should see the tube neck dimly lit up orange. These checks will give you a more precise answer to your problem .

I just got a Clarion DXZ385USB deck installed, but the screen does not appear blue as in the product pictures. It is dark and barely readable. Dimmer is turned off. Any ideas?

I didn't have to connect the illumination lead. If you have the battery wires(yellow) connected, the screen will light up pretty bright. When I connected the illumination wires(orange), I got the same dim screen light effect.

Sorry to tell you this but you have a bad FMT board which is not available. When this board goes out it will display a checkerboard pattern on the screen, or it may not even turn on the timer light will just keep flashing.

Monitor too dark....

Usually every laptop has the option of adjusting the screen brightness as you would want the screen to be pretty dim when running on battery to conserve battery life.
First thing to check would be just that.
