Attach an external monitor to the laptop and boot the laptop.
If you get video to the screen then it is probably the inverter for the laptop screen has failed and can be replaced.
If you have no screen available, then turn the laptop on, shine a bright light into the screen from an angle and see if you can see any kind of images at all. Best to wait 2 minutes from when it is first booted to allow enough time for Windows to load.

Hope that helps =)

No display on screen of my old insite laptop

Are you sure it's going into power save? When you boot it up does everything seem to work except the screen is black? If so, that's not power save.

Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.

The power. Is on the computer is running, however. The screen is blank. What wrong no picture

See if the problem is in the Display Assembly, or the graphics chipset.

[ The Display Assembly is essentially the laptop's monitor.
A) The plastic Display Bezel in the front.
{Thin plastic frame in front of the LCD screen, and surrounds the LCD screen. Resembles a picture frame}

B) The LCD screen assembly.
{An LCD screen is composed of layers. The layers are held in place by a metal frame. This frame also resembles a picture frame}

C) The screen Inverter.
{Converts the electricity from the laptop for the Backlight, and LCD screen}

D) Webcam if installed

E) Backlight
{An LCD screen does not produce light. It needs an additional light source.
A Backlight is the additional light source.

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

F) Brackets on each side of the LCD screen assembly, plus various screws ]

[Graphics Chipset:

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

The graphics chipset is a GPU.
Graphics Processing Unit,

Most of the time with a laptop, the GPU is soldered directly to the motherboard in a laptop.
Not removable ]

Laptop OFF, monitor OFF, attach a VGA monitor to the VGA connector on the laptop.

The VGA monitor can be a CRT monitor, (Looks like a small TV), or a flat LCD screen monitor with a VGA cable.

This is an example of what the VGA connector will look like on your laptop. May be on the back, or on the side, (Top right of page),

Turn the monitor on. If a CRT monitor allow it to warm up.
Turn the laptop on. By default the display should automatically be on the external monitor.
(VGA monitor)

If not press, and hold down on the Fn key, and tap once on the display toggle-over key.
(One of the F function keys at the top, (F1, F2, F3, F4, etc), will have a monitor symbol on it, with an arrow, or another monitor symbol close to it. This is the display toggle-over key.

If I knew the Model Number of this IBM laptop, I could tell you, and possibly show you, where the VGA port is on the laptop, and what key is the display toggle-over key)

Still no display on the external monitor? (VGA monitor)
Tap the display toggle-over key again. (Remember, you have to hold down on the Fn key at the same time)

No display on an external monitor, means there is a problem with the graphics chipset.
Generally requires motherboard replacement.

Display on the external monitor, means there is a problem with the laptop's internal monitor.
(Display Assembly)

As stated, an Inverter converts the electricity from the laptop, for the LCD screen, and the Backlight.

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

Average cost of an Inverter varies, from $22 to $45.

Post in a Comment as to the Model Number.
This is in a white Service Tag, or sticker, on the Bottom of the laptop.
Perhaps I can find an HMM for this laptop.

Lights come on, but blank screen

Hi estees823,

If you see power lights but nothing appears on the screen, it could be a "POST" (Power-on Self Test) problem or simply LCD problem.

Here are some steps that you can try.

1. Remove the battery and the ac adapter then press the power button for at least 20 seconds to drain electric charges left from the system. (You may need to repeat this step to get it work.)

2. If above step doesn't work, try to plug in an external monitor and see if you get display from the external monitor. You may need to press the Fn + F4 or F5, depends on the key designed on the keyboard to toggle between displays.

3. If you get display from the external monitor, I'm sure your having problem with the LCD components. In this case, check and replace faulty LCD backlight, LCD cable or LCD inverter. The LCD inverter is often a culprit.

4. Try to reinsert the memory module/s (RAM) of the unit, try using one RAM at a time to see if it works. A faulty RAM will cause the laptop not to POST.

5. If reinserting the RAM doesn't help, most likely your motherboard needs to be replaced.

Hope this helps.

I have another vga monitor connected to travelmate 2300. what buttons do i press to make it work?

The key sequence can vary depending on laptop, however is often either: Fn + F3, F4, F5, F8, or F9. This means if you were fore example to press and hold Fn + F3 at the same time it'd switch between your laptop display to your external display. The function key will often be labeled as CRT/LCD or have a picture of a monitor on the key or close to the key. Unfortunately, the keys pressed to switch displays is dependent on the model and manufacturer of the laptop. If none of the above key sequences work, consult your laptop documentation or consult your laptop manufacturer

I have acer laptop model Aspire 5738Z series. When i switch on my laptop,no picture is coming from the LCD totally blackout...but there is power indicated in the main board. Before it happened i didn't use...

I'd recommend that you find an external VGA monitor and connect your laptop to it to see whether you can get a picture on the external screen whilst the laptop is switched on. You may need to toggle the display mode by pressing a specific function key (Fn + F5) in order to get the laptop to output the VGA signal. The exact function (Fn) key can vary from F5, F8 or F9 etc depending on your laptop but in general you're looking for a function key with a square on it. If you can get a picture on the external screen but nothing on the laptop LCD it might be that the inverter has blown. If you're feeling brave replacements can invariably be found on eBay and an online guide will walk you through the procedure. Good luck.

I have a Compaq presario CQ61, an when i turn it on the screen is black other than some really dim writing i can hardly see. Help?

Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

Connect laptop to external lcd monitor

This laptop has a blue VGA port. Plug your monitor into it. You might have to adjust the BIOS to recognize the external device.
Once connected, your laptop may automatically switch to the new external display or you may be required to press a sequence of keys in order to switch from the laptop to the external display. The key sequence can vary depending on laptop, however is often either: Fn + F3, F4, F5,F8, or F9. This means if you were fore example to press and hold Fn + F3 at the same time it'd switch between your laptop display to your external display. The function key will often be labeled as CRT/LCD and/or have a picture of a monitor on the key or close to the key. Unfortunately, the keys pressed to switch displays is dependent on the model and manufacturer of the laptop. If none of the above key sequences work, consult your laptop documentation or consult your laptop manufacturer.
Some laptops also have the ability to have the display on both the laptop and external display and/or one or the other at a single time. Laptops with this ability can switch between these modes by continuing to press the same function keys until in the mode the user wants.

When pluging in an exterior monitor, nothing apears on the exterior monitor?

Try power up the monitor first then the notebook.
This will automatically switch the video output to the external video port first. If this doesn't work then most likely there is a video card fault.

Black screen on acer 242lc lights come on power up

You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Here's a link for ordering that part. From all that you described it most certainly sounds like the motherboard is done for, unfortunately. Hope this helps.
