I have hooked up an external monitor to my toshiba satellite l305d notebook. When i go onto screen resolution and detect it the external screen shows up, i just cant get a picture on it. It used to work, wondering if i can download a driver for it, whether the screen may be the issue (it works fine through hdmi for my ps3 but not the VGA with my laptop). i used to be able to connect the external monitor and it worked fine, now it just says there is no video signal detected

try holding down your Fn (function) key then taping the F5 key (change monitor) on startup. also you can try to plug in an external monitor to see if you can change back to laptop monitor.

Hi oysertails...
Try hooking your laptop up to an external monitor...if you can see the picture on the external monitor then your lcd screen may need replacement or the lcd inverter board.
Please take time to rate me

1) I would suggest you disconnect the video cable from the laptop (Motherboard) to the LCD screen, and the Inverter cables in the Display Assembly.

2) Then attach a VGA monitor to the VGA connector on the back of the laptop, so you can see what is going on.
(Laptop off, monitor off, attach the monitor)

I'm going to just assume damage to the LCD screen itself, and not possible damage to the entire laptop, since you just indicate a broken LCD screen.

If the laptop was closed during being damaged, the problem may lay deeper than just the LCD screen.

(For one example; If the laptop was closed, and damage occurred to the body of the laptop, the cooling fan assembly may be damaged, and the fan isn't spinning.

The Processor, and the GPU, need air to cool them. They operate within a certain specific temperature range.
Too hot and BIOS turns the Processor off. {No Processor operating, no computer)

If the LCD screen was damaged towards the bottom, damage may have occurred to the Inverter, also.

To disconnect the video cable from the motherboard:

1) Remove ALL power to the laptop. Remove the AC adapter (Charger) and Battery.
Work on a table.

2) Observe Anti-Static Precautions

3) Follow Steps 1 through 7 on this page, {Page 1}

4) Follow Steps 8 through 14 on this page, {Page 2}

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L305-L305D/remove-screen-replace-video-cable-2.htm

Follow Step 15 on this page {Page 3},

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L305-L305D/remove-screen-replace-video-cable-3.htm

You have to remove the Keyboard Bezel, then the Keyboard, then the Top Cover.
(Palm Rest Cover actually. Top Cover is Toshiba's nomenclature), to access the video cable's connector on the motherboard.

You have to remove the Display Bezel to access the Inverter.

The video cable's connector on the motherboard, is shown more clearly in Step 20 on this page {Page 3},

For more clarity here is a link to a free Service manual, for the Satellite L305D series of Notebook PC's,

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-toshiba

Scroll down with your eyes to the second Satellite heading. The one that begins with Satellite A10.
Go to the second line in this 'paragraph', and left-click right on - L305D

This is a PDF file. (The computer you are using now has Adobe Reader on it, which uses PDF files)
After you click on the file name, (L305D) it may take up to 30 seconds for the first page to come up.
It may also take additional time for the file to fully download.

I would use the Zoom Out icon in top header of the PDF file, to reduce the view size to 100 percent.
( It's the Minus { - } symbol )

Go to Page 176. (4.12 Display Mask)

In the top header of the PDF file is the page number box. It is to the right of the Down Arrow.

You can use the Down Arrow to go to Page 176, or;

1) Left-click once in the page number box
2) Type 176
3) Press the Enter key

With the video cable disconnected from the motherboard, and the Inverter cables disconnected from it (Inverter), and the VGA monitor connected to the laptop;
Install the Battery, THEN plug in the AC adapter. Plug the AC adapter into power.

A) Turn the VGA monitor on. Let it warm up until graphics show.
B) Turn the laptop on.

If the graphics from the laptop is Not displayed automatically when the laptop turns on;

Press, and hold down on the Fn key, tap the F5 key.

There are three possible displays available;

1) The laptop's LCD screen only.

2) The laptop's LCD screen AND an external monitor. (VGA monitor)

3) The external monitor only. (VGA monitor)

Tap until ONLY the VGA monitor is on.

{VGA monitor. Looks like a small TV. It is a CRT.
You can also use an LCD flat screen if it has a VGA connection, and a VGA cable.

VGA connector on laptop. Believe it is on the Right to the very front.
Don't know as I do not have a Satellite L305D-S5985 Notebook PC in front of me, and the User Guide on Toshiba eSupport is unclear.
Doesn't show the sides, top, and bottom of the laptop.

This shows you what a VGA connector looks like more clearly,

Good graphics on external (VGA) monitor?
Shut the laptop down normally.
Remove all power.

Connect the cables to the Inverter again. (NOT the video cable)
Reinstall the Battery, and AC adapter.

(Caution: It is NOT a good idea to have the AC adapter plugged into power, when disconnecting, or connecting to the laptop. You could get a voltage spike, and fry the AC adapter, laptop, or both)

Turn the laptop on.
Still good graphics?
Suggest you replace the LCD screen.

When obtaining an LCD screen, check the LCD screen's manufacturer code on the back of the LCD screen. Match it up to what the replacement LCD screen website indicates is a match.

Has to be a compatible LCD screen. The Inverter, and LCD screen are a matched set. They are both matched to the laptop.

It would be best to buy, and wear an ESD wrist strap. Connect it's alligator clip to a good ground source. For an example, I connect to an unpainted surface of the metal frame, of an empty desktop computer case.
Average cost of an ESD wrist strap is around $3 to $5.

Cheap insurance to keep from static shocking your laptop, and have an expensive paperweight.

Use a multi-compartment container for the various screws you will remove. Label each compartment for the area the screw/s come out of.
If a multi-compartment container is not available, substitute with a clean egg carton.
Label each egg holder.

Some screws look VERY similar to others. DO NOT mix them up.
(For one, a wrong screw could screw in halfway, then be stuck.
Won't go in any further, and if you try to take it out it may twist off.
Not to mention what a longer screw than needed, may do for damage in the wrong hole)

Post back in a Comment as to your findings. Also post any additional questions in a Comment.

You can see the disassembly process in this link:

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L305-L305D/remove-screen-replace-video-cable-1.htm
You can replace the screen with any LCD panel with this conditions:
Backlight: CCFL Resolution: 1280x800 Size: 15,4.
For example this one will work:

If you checked with external monitor, the inverter board sits under the screen housing is more than likely the problem, failing that! the lamp inside the screen housing, either way a computer tech is recommended.

Hi there,

The way to find out if it's just the screen is to connect the laptop to an external monitor. Pay attention to the F keys when you connect the laptop. On most Toshibas, you'll see a small depiction on the F5 key of a laptop next to a monitor. You either have to press that key alone, or hold down the fn key and then press the F5 key and let go to transfer the signal to the external monitor.

If the external monitor shows up good and you can perform all other functions on your laptop while viewing the monitor, you need only replace the laptop LCD. If it does not display correctly, then you're into the next round of troubleshooting.

Hope it works as above.

Good Luck

There are also another reason , the Back light lamp might be damaged also!

How about the LCD inverter? Did you replace the inverter? It is probably not the actual LCD but just the inverter that needs changing. Give it a go, they are inexpensive, try eBay.

Look carefully at the screen, you should see some very faint images while its booting up. IF this is the case you need to replace the inverter.

If your system won't display anything w/o the external monitor. there's something wrong with the LCD's backlight. you may have to contact your laptop's manufacturer and check if this laptop is still under warranty. you may have to get the lcd replaced.

thanks.
