Sony Vaio E Series VPCEH37FX screen goes dark, but fine otherwise


If you can see faint dim images on the screen, then your back light or power inverter has failed. They are not adjustable or repairable and must be replaced. If you can't see anything on the screen, the LCD has failed and must be replaced. Sometimes it's hard to see the dim images so use a flashlight to help determine if there is any image on the lcd.

Dell f700 powers up but screen remains blankno picture at all


If you still can see an faint or very dim image on the screen.
Use a flashlight to see if you can see a dim display on the LCD.
If you cant see anything it isn't worth fixing, If you can then you need to change the inverter. You can get them for around $20.

Audio really does not matter here---in a very dark room shine a flashlight at the screen with set on to see if you see a very dim image on the screen or not.

Check it on an external monitor to see if the video card is good. If the external works, then the LCD or backlight is bad. Look with a flashlight. If there is a very dim image, then it is probably the backlight. If no image, then the LCD.

Black screen after a year of use


Sine a flashlight on the screen and check for a dim image. If you see a dim image the back light needs to be replaced. After doing that you will want to try using another monitor cable and see if that helps. If it doesn't with the computer on and the monitor on disconnect the cable from the computer. If the monitor shows a no signal error the graphics card needs to be replaced.

Dim picture


This is the way how to examine where the problem is. If the screen is going dark. You have to check that you can see the image on screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons (Power on both cpu and monitor), there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken. If you cannot see any icon on the screen. I would say that there are some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or dark spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
