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.

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,

Click on Display.

An LCD screen does Not produce light,

(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.

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?]

For additional questions, or to have me clarify anything I have stated above; please post in a Comment.

My screen is so dim on my dell vostro 1500. my kids play educational games on it and i'm worried it's so bad for their eyes. the fn key does not work. please help!m thank you.

You can try to go to the power settings and adjust to brightness of your portable system. There should be a battery icon on the lower right portion of your computer, double click it and you should have the power setting. On the bottom portion, there should be a lever where you can set the brightness higher. if this does not work try to adjust contrast in the nVidia Control Panel (assuming you have an nVidia card).

In Vista, go to
Display Settings->Advanced Settings
Click the GeForce tab
Click "Start the NVIDIA Control Panel"
Click the "Display" category
Click "Adjust desktop color settings"

The screen on my Dell Inspiron E 1505 is dim to almost black. Looking closely I can see a little bit and when hooked up to an external monitor I can see my desktop. Is this an expensive problem to fix? ...

sounds like a specific issue with the LCD of the notebook. if the ac adapter is already connected to the system and same issue, try to adjust the brightness level of the LCD usually by pressing FN + up arrow key or FN + right arrow key. if this does not work, you can try to remove and reconnect the LCD cable to the motherboard. If all else fails, proceed to get an LCD replacement either through warranty if available, or by ordering a new LCD.

Monitor black out

Someone adjusted the brightness on the system for AC power mode. Turn on the system with the AC power plugged in, hold down the "Fn" key in the lower left of the keyboard, then press the up arrow in the lower right. This will increase the brightness; set it at whatever level looks good to you.
