Are you good with a screwdriver? Here's a step by step procedure for replacing the LCD screen on a Dell 1500.

Is fairly easy, but be extremely careful of the ribbon cables, they break very easily!
Good Luck!

1500 has dim screen. Switched screens with working 1500 and screen works as it should. Hooked up external monitor to bad 1500 and had good picture on monitor. So screen is fine. I have tried FN + ^ arrow...


Fn with ^ key? Why? The Display Toggle-Over key is the F8 key.
Fn key plus UP Arrow key is to increase the Brightness.

You hold the Fn key down, and tap once on the F8 key.

(Of course there are at least 3 display options available;
A) Laptop internal monitor ONLY.
B) Laptop internal monitor AND external display device.
C) External display device ONLY.

You may have to hold down on the Fn key again, and tap once more on the F8 key)

You switched LCD screens with a working one, and it works OK.

Reason is you also switched the screen Inverter, too. Correct?

The screen Inverter is mounted to an area at the bottom of the LCD screen, and behind the Display Bezel,

Primer:
An LCD screen does Not produce light,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

(Click on the monitor image)

It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, (Or two of them); Or a series of LED's.
(Light Emitting Diode)

The Dell Vostro 1500 series of Notebook PC's, uses a single CCFL for a Backlight.

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

Average thickness is -> 2mm. That is a little larger than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height.

http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

View the last 8 photos.

It is just like Fluorescent lighting used in homes, and businesses also, because it has MERCURY vapor inside.
HIGHLY toxic.

A screen Inverter is used to convert the power, (Electricity), from the laptop, for the LCD screen, and Backlight.

(NOTE* Does NOT apply to laptops that use LED backlighting.
There is NO screen Inverter used)

90 PERCENT OF THE TIME the fault is a bad screen Inverter.

Primer over.

Me? I would buy a screen Inverter, due to the low cost, and ease of accessing to replace, and replace it, and use the old LCD screen.

[ You did check Video Cable connections -> PHYSICALLY, (Try to plug in tighter), on the Video Cable motherboard side connection, LCD screen connection, and screen Inverter connection; correct?]

In my dellvostro a860 , rite side of the screen colours are spreaded,it it looks like shade,,whats the problem in that i m not getting please help me..........


It is the screen Inverter, or the LCD screen itself.

Screen Inverter: A small circuit board located behind the Display Bezel, and mounted towards the bottom of the LCD screen,

http://support.dell.com/support/edocs/systems/vosA860/en/sm/display.htm#wp1183775

The yellowish long object, at the bottom, is the screen Inverter.

Here is another look at it,

Dell Support > Vostro a860 Notebook PC > Service Manual,

http://support.dell.com/support/edocs/systems/vosA860/en/sm/index.htm

In the list clicking on -> Display, will get you to the first link above.

Need guidance in replacing the screen Inverter, post in a Comment.

(Just a basic guide using a Vostro 1014/1015 Notebook PC. Not yours, but good for basic guidance. This is replacing the LCD screen,

http://www.insidemylaptop.com/replace-lcd-screen-dell-vostro-1015-1014-laptop/

[ Primer:
An LCD screen cannot produce light by itself,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

( Click on the small window with the monitor in it )

It needs an additional light source. A Backlight is the additional light source.
A Backlight can be a CCFL, (or more than one), or a series of LED's used as lights.

The Dell Vostro a860 Notebook PC uses one CCFL, for a Backlight, OR there are Vostro a860's that use LED lights.
(If you replace the LCD screen, make sure FIRST of what type of Backlighting it uses)

A CCFL is a Cold Cathode Fluorescent Lamp. Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

[Average thickness of a CCFL is 2mm. That is a little larger than 1/16th of an Inch.

A screen Inverter is used to convert the power from the laptop, for the Backlight, and LCD screen.

Most of the time the fault is the screen Inverter.

The Vostro a860 Notebook PC's, that uses LED's as a Backlight, MAY also use a screen Inverter.

For your problem it could be the screen Inverter, but I lean more towards the LCD screen itself, is the problem.

How to test a screen Inverter? Requires a very sensitive multimeter.
Read; Expensive,

http://www.fonerbooks.com/test.htm

For a layman who does not have access to a sensitive multimeter, the method is to just replace the screen Inverter, and see if it is the problem.
'Parts changing', I know, but if you do not have the proper equipment to test with?

Screen Inverter replaced, and problem still persists, replace the LCD screen,

Dell Vostro 1500 Repair manual and parts for backlight and inverter


You cannot replace the backlight. It is incorporated into the lcd panel and not available as a separate part. The inverter board is very easy to replace. It is located right behind the dell logo at the bottom centre of the display panel. Remove the screws on the front of the lcd bezel (under the rubber pads) and the inverter board is right there. Call 1-800-www-dell or look on ebay. Hope it's only the inverter board, as a new lcd panel is $350+. If the display is dead you can still use the laptop by connecting an external monitor to it.

Hope this helps!....let me know how you make out.

Dell Vostro 1500 - just replaced a broken LCD screen. New screen is dim. I already checked color connections and screen brightness (FN up and down). How do I brighten my screen?


You are probably not going to like my answer but your new screen may have a bad Backlight or connection, that is what lights up the lcd panel. Check your connection at the inverter just to make sure, sometimes these connection can get reversed or get loose during the reinstall. I would take it back apart and check it from the main cable on the back all the way to the motherboard.

The LCD display dims almost to black after 20-40 mins.


Power save settings or it may have an ambient light sensor that automatically adjusts the screen to "match" the surrounding light. Power settings in the control panel will hold the key.

Vostro 1500 LCD


Your unit uses a fluorescent backlight and an inverter to provide the high voltage for it. Considering that it varies in intensity, it isn't likely a failing fluorescent tube (these will mostly fail gradually and not recover) but rather the inverter and this is often a small separate board that is replaceable.

Screen dim


It could be both. But usually it's this order:

inverter, backlight, lcd, video card, lcd cable.

I always start by checking out the inverter first since it's the easiest as well.

The cheapest place to get a replacement is eBay for sure.

Best of luck!
