Plugging into a different screen doesn't work

It is not working. Actually we can see the screen a tiny bit (on the laptop itself) but so faintly that we can't see the mouse arrow enough to use it for transporting data to a flash drive. Plugging it into another screen doesn't work at all

The Cold fusion lamp in your LCD and or the invertor board for the LCD could be bad that is the reason why a faint image . As for the external monitor you should enable it by the Fn+F5/F6/F7 key by pressing it twice at boot up before windows is fully loaded - this to ensure that the external monitor works with your laptop . If the resolution setting and frequency is not comaptible with external monitor you connect then you wont have display on your external monitor . Start windows in safe mode .

Power is on but no display in the screen


You didn't give much info to work with, but, Could be a couple of things. 1) The backlighting (CCFL) may be out. If you can see the desktop as a faint image in a very bright light I would suspect the CCFL, there is a tiny switch that shuts down the backlighting when you close a laptop, sometimes it can get stuck. Also if the laptop is dropped, jarred, etc. 2) the wiring to the CCFL could be pinched, broken, and the obvious the Light itself may have burned out. 3) There is a ribbon cable that connects the monitor to the motherboard that may have a bad connection.

After storm, my keyboard is not working . So i use my brother's keyboard and test whether it is still work or not . But it also doesn't work, so whats wrong with my computer ? Can any kind person...


It seems that you may have lost connection to the keyboard inside the machine or it could be the plug itself. Most of the ones i couldnt fix went online and got the on screen keyboard. Its a bit unusual to use but it buys time until u get a new computer or find someone local to check the internal connections.

Half of my computer is black? what can i do to fix it?


I"m assuming you mean the picture on the screen. One of your screens backlights has burnt out, or the screen is cracked/damaged in some way. Shine a bright light on it and look closely, if you can see the image faintly, then it's the backlight, they can be changed if you know what you're doing, but theres LOTS of tiny screws. You may want to buddy up with your local geek and offer him something yummy or green to fix it.

Otherwise if it's the screen itself, you can sometimes get your same model laptop off of ebay in 'parts' condition for the screen, or the LCD itself if you open the case, again, making good with your local geek can get this done for you.

An alternative would be to just hook up a regular screen to it, if it has VGA/DVI out, kinda robs it of it's 'laptop' status, but at least you can use it until you can fix it.

Black screen / works on external moniter


When you turn your laptop to different angles can you see extremely faint graphics? Try shining a bright light at it an turn it at a 60 degree angle to your eyes. If you can see any graphics then your inverter board is bad. It it located just below the screen in front of the keyboard. The inverter itself is very inexpensive (about $12). Having someone install it shouldn't take more than 45 minutes. Let me know if this helps you.

Computer works fine but has a blank screen. I have it hooked up to a monitor right now and it is fine except for the blank screen.


can you see anything on the screen at all? Look very closely at the screen from different angles under a strong light and see if you can see a faint image on it. If you do it means the back-light is not turning on which is usually a failed inverter board (cheap and easy fix). If you can't see anything at all on the screen then either the cable is not seated properly or is bad (not very common) or the screen itself went out (more expensive repair)

Dark pink Dell Inspiron 6000 display


Your wallet will be yelling a bit. The display problems are typical of the back lighting system going out. These are the lights inside the display that light it up enough for you to see it. Without them the images are still there but too faint to see. There is nothing actually wrong with the lcd just these lights.

A typical back lighting repair kit will be about $100 for the parts and then there is the labour. You need to consider the cost of repairs verses purchase price of a laptop. There are some very capable new ones out there for about $400. Unless you can repair it yourself (not hard) or your techie will work cheap for you on this, you do need to consider replacement. Before you rush out to buy a new one make sure there is no warranty left from either the manufacturer or the store you bought from.

I know of lots of people who would just use it as a desktop system with an external monitor keyboard etc.

So you need to consider if you need it portable, if you want to spend the repair money or if a new one would be money better spent. Sometimes if it is a higher end laptop it is definitely worth fixing even if it is a few years old.

Screen Problems with my Laptop


hi dear

1. That can be connection related problem. I check connection between the video cable and the LCD screen, try reconnecting the video cable. It’s necessary to take apart the display panel, unplug the video cable from the connector on the back side of the LCD screen and then plug it back in. In some cases reseating this connection helps. 2. If reconnecting the video cable doesn’t help, here’s what I do in this case. While the display panel is still disassembled, I turn on the laptop and wait until image appears on the screen. Then I move the video cable a little bit without touching the LCD screen. If moving/touching the video cable affects image on the screen, it’s possible that there is a problem with the cable. Apparently there’s a short somewhere inside the cable. In this case, replacing the video cable may fix the problem.
3. If reconnection the cable doesn’t help and moving/touching the cable doesn’t change image at all and the only way to get better picture is moving/touching the LCD screen itself, apparently there is a problem with the LCD and it has to be replaced.


oke

It's all black


If you power it on, take a flashlight and shine it on the lcd at and angle and look real close to see if you can see a faint image. If you can, then your backlight in the screen is not working.
Also, you can attatch an external monitor to it, while its off, then power it on and see if it lights the external monitor. Try that and let me know your results.
If you get a picture ok on the external, and you can see a faint image on the lcd using a flashlight, then it could be the backlight inverter board or the bulb itself inside the lcd went out.
If you don't get any picture at all, using an external monitor and can't see a faint image on the lcd using a flashlight, then I would say there's other problems with the laptop itself. Could be a mainboard problem, power issue, etc..
