The power light turning orange means the monitor isn't getting a signal from the computer. Or the monitor has a problem. If the screen shows light in the corners, the inverter is working. (If the inverter stops there is no light at all.)

The first thing to try is connecting another monitor to make sure your computer is actually starting up. If that monitor also shows nothing, you have a computer issue to take care of. Otherwise the monitor needs service.

My viewsonic va702b will flicker on for less then a second then goes off. The green light stays on but has a black screan. Whats goin on.


This is a common problem with this model. The capacitors in the power supply board have failed and are preventing the unit from powering up. Here is a link to a repair kit with the correct capacitors and a pictures showing where the one are located that need to be replaced. Very easy repair.

No Image on screen, Faint inage on the screen when held in front of a light, Outputs to external monitor, when you toggle Fn & F2 screen flashes on for a second


Hi

This is an inverter problem normally. But still there are ways to diag. the problem please follow the below steps just to rule out the bad inverter.

1. Try to check if the small button used by the LCD to turn off the LCD back-light is stuck. you can find it in some corner or little adjust-cent to the power button.

2. The signal cable connecting from motherboard to the LCD may be loose.

3. If your power adapter is not supplying enough power to the motherboard will also effect the brightness.

4. Make sure you have used the option to bright the back-light by using Fn+f4 or f7 in some laptops.

How do i dim the screen brightness on a dell inspiron 1525 laptop


Look at your keyboard some of the keys have blue symbols on them, that's the second function. At the bottom left of your keyboard next to the control key there's a button that says Fn on it hold that down and then press one of the other buttons to use the second function. The brightness control is the up and down arrows. Hold Fn and press up or down to change the brightness.
Also if your laptop is set to a lower power setting the display wont be as bright. Click on the little battery symbol at the bottom right hand corner of the screen a little menu will pop up that says select a power plan if its set to power saver your screen wont be as bright.

Screen will not stay bright


That's the battery saver feature of that Philips portable. If you use an A/C power adapter, the light will stay bright.

Hope this helps!

Nintendo DS lite power light comes on but both screens stay dark?


When you boot the Nintendo DS you can change the illumination settings in the main menu.
One the main menu, you will find a sunny symbol in the lower left corner of the screen. Click on that and you should be able to change the level of illumination. If you are also wondering if you can change the brightness during game play, you can't. Games such as Mario 64 DS come with support for brightness change but otherwise you have to do it before game play.

Monitor going black after a few seconds can be caused by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4 bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.
