Hi

It could be an issue with the monitor or the software or the drivers for the graphics card.

Pls uninstall the display drivers, restart the drivers and reinstall the display drivers and then restart the computer once again and check the display.

Also pls install the monitor software that came with the monitor.

Also you may try downloading the original display drivers and any driver updates from the graphics card manufacturer website and check the display.

If the above steps doesnt work, then the monitor has to be serviced or replaced.

Tip

LCD monitor displays background fine for a second then goes black


If your LCD monitor displays your desktop fine as it boots up and then goes blank after a few seconds, but you can still faintly see your desktop then this may seem like a brightness issue but it's not. The picture displays very faintly, this is because the LCD backlighting isn't working properly. Which in turn is either because (most likely in cases like this) the inverter circuit has failed or the cold cathode tube has blown. If you're new to the electronics business and are not sure how to solder and connect circuits then this is the job for a qualified repair technician. So i suggest you head on down to your local PC store and have a technician take a look.

If you want to try it youself go here to order some spares.
If the monitor switches off and you can't see your desktop faintly then this may just be a power saving issue. Yo fix this check out my other tip here.

If your monitor is less than a year old then I suggest you take it back to where you bought it and have them send it in for repairs or swop it out with a new one. LCD monitors usually have at least a 1 year warranty sometimes it can even be up to 3 years if you register yours when you purchase it or if it's a really expensive screen.

If the monitor is a good 4-5 years old then it may not be worth fixing or may be too expensive. I suggest you invest in a newer widescreen option. LCD monitors have drastically come down in price over the years and you can easily get a wopping 23" for as little as $180.

2 tiny black spots on screen, one looks like a check mark and one is a dot. Toshiba laptop satellite series. Dead pixels? How can they be fixed. Ran a program that is multi colored flashing lights to no...


Unfortunatly you do have dead pixels, but you cant fix them. Lots of lcd displays have them, some are more noticable than others, it dosent mean your lcd monitor is going to fail soon or anything like that, even brand new lcd monitors have dead pixels it is a comman anoying problem with them.

Lenovo 3000 n100 lcd display works but only less than a minute before display goes black. Connect an external monitor and it works fine.


possible problem is your led light on your LCD or its Flex. you might need to have it replaced. Try to check your LCD when it turns black under the light if you can see a dark image of your desktop. If you can see your desktop then the backlight has a problem. If there is no display, your LCD needs to be replaced.

The l226wtq goes black


Try shining a flashlight on the screen, or without the flashlight, try to see if you can distinguish anything on the screen at all, if you do, the backlight is dead, or the monitor has an internal most likely unfixable problem.

Hi I am fairly good with computers but i dont know how to fix this problem. My advent 7113 laptop turns on the power light comes on and they the fan starts but am not sure if the harddisk boots. Then...


It sounds like Either the onboard video card or the LCD controller has gone bad. To verify which one connect a monitor to the VGA adapter on the back of the Laptop. You may also have to hit a key combination to swap displays (Usually <Fn> + <F5> but may be different the keys usually have an offset that indicates its function.

If the Monitor displays the same black and white anomaly then the vid card went bad, if it displays a normal screen your LCD controller is faulty.

Either problem would likely need service from an experienced technician

Hope this helps

Laptop comes on but monitor remains black


Hello,

IT could be one of two things. First make sure that you have the laptop set to display on the LCD. Most laptops will have a Function key labeled by Fn then you will need to look at the function keys at the top F1-F12 and find the one that either says CRT/LCD or has a picture of a screen or monitor. Then, after you have found that key, you will need to press and hold the Fn key and tap the appropriate function key, this will alternate between the LCD (laptop) and CRT (monitor). If you have trouble finding the correct key combination for switching displays should be listed in the manual.

If that doesn't correct it, then I would try locating a desktop CRT and connecting it to the monitor connection on the rear of the laptop and again pressing the keys to switch between CRT/LCD. If it shows on the CRT then I would say that the LCD on the laptop is bad.

Thanks

My emachines monitor has no picture, hard drive is functioning properly. Monitor is black


if you do not get a screen with a LCD monitor its likely you have a inverter problem or BACKLIGHT problem. you might need to replace the LCD backlight or replace the monitor on the desktop.
check to see if the laptop can get a picture by plugging in a monitor to it, im sure theres a connection for external monitor.

theres also a FN (function key) command to switch from lcd to external monitor. always test before commiting to replacing a monitor.

The desktop, you might want to test another monitor on the desktop just to be sure the monitor is gone or dead. if you see on the monitor a OSD saying "No power or No Signal" or you can pull up the OSD(on screen display menu). then the monitor is not dead.

might be the computer even though the computer powers up doesnt always mean the computer is working.

i would check the motherboard for blown capacitors or funky smelling(burnt plastic)aroma. Make sure the computer is off before checking.

get back to us!

thanks

PC or monitor, signal problems


your monitor is telling you it's on it's last legs..either that or your compaq has a bad video section. either is more vital than a video cable being loose.
