Question about Dell E173FP 17" LCD Monitor

1 Answer

Dell Latitude LCD screen is dark, but computer is still working.

I have a Dell Latitude D505 that suddenly developed a problem with the LCD screen. I turn it on and can very faintly see that it is booting up, but it is so faint that I can't use the mouse or keys to login or use it. I have plugged a monitor into it and can use it just fine this way, so there is nothing wrong with the computer itself. Since I can see the screen very faintly I'm thinking tht the backlight must be working in some capacity, but is there a way to adjust the light? What could be wrong? Can anyone help?

It sounds like the backlight has burned out. The faint light you are seeing is ambient light in your room being reflected through the LCD. Try it in a perfectly dark room and see if you can see anything on the screen. The following page should give you a sense of what is involved in replacing a backlight: If you aren't comfortable taking things like this apart, I would recommend finding a local repair shop to replace the backlight.

Display is very dark and can barely be viewed. Brightness controls don't do anything. Any suggestions? It is a Dell latitude 505.

Sounds like the back light has gone.
You may be lucky and you just have a loose connection, its worth taking the front off the screen surround and re-seating all conectors.
If it is the backlight, you can get a replacement quite cheap (£10)

Dell Latitude D510 Screen Failed


The 14.1" inch screen is compatible with Latitude models D500, D505, D510, D600, D610 and Inspiron models 500m, 510m, 600m.

You may also need a screen inverter - in fact that is often the reason a screen is considered to be failing. The lcd inverter can be one of the most common items to become defective in a laptop computer. You may need a lcd inverter replacement if your screen is dim, dark, colored oddly, blinking, flickering or has dark stripes. Just something to keep in mind.
Hope this helps,

Vertical red line in display

I had a similar problem with a flat screen lcd for my desktop comp, and it turned out that I needed a new screen if i wanted to get rid of it, but it doesnt really cause much of a problem, so i didnt bother replacing it. If your laptop is still under warranty, (i dont know how long your warranty lasts) I'd look into getting it replaced if it really bothers you. But yes, its definitly the screen.

Backlight of LCD turns off

For latitude systems they have this ambient light sensor. it basically adjusts the brightness of the screen depening on room lighting. try to go to bios by hitting F2 on the dell logo. go to video and try to look for ambient light sensor. however, im not sure if your computer has that feature I have a second option for you though. based on the troubleshooting you've done, it seems that the video back lighting is affected by movement. it would be a good try to reseat the LCD cable. you can use this link to guide you in fixing the computer :
all you need to do is to take out the keyboard with 2 screw holding it in place. the LCD cable should then be accessible. it a thick cable that coming out of the Left hinge.

Hope this helps.

Black Spots on LCD for Latitude D505

If you?re positive that the black spots aren?t dirt or scratches on the outside of your screen you are probably dealing with dead screen pixels. Short of replacing the LCD screen there is no way to repair them.
