My Compaq computer is switching on and powering up normally, but although the opening screen (the encrypted texts, the logo of Windows X.P) shows up, the screen is blank. I switched it off and temporarily removed the battery several times over, but it keeps showing a blank screen. The opening proceedings are fine, but there is nothing displayed on-screen that follows. Please may you help me?

moe, the first thing I'd do is to attach it to an external monitor. If the external monitor comes on, it is something with your LCD. Could be the cable, the inverter or the LCD panel itself. If the external monitor does not work, you are having issues with your video card, which is an integrated part of your motherboard. You can download the service guide from here and it should help you with your laptop. Hope this helps, good luck.

I dont know but i hooked it to an external monitor and it didnt show anything. Is there anything i can do and is it worth it.

by

That is a depends question. Depends on what it needs. If you are sure it comes on but your display is not showing anything, it sounds like a bad video portion of your computers motherboard. Sometimes this can be resolved by a reflow, sometimes it will require a new motherboard. A replacement should not cost you more than $100 and it is cheaper than a new laptop....

If i connect an external monitor, it showing but problem with the attached LCD. When i turn on the laptop, the light of the LCD panel is working but the screen is blank. Sometimes it automatically working, if i restart the laptop again the same problem arise.

Please suggest.

I have the same problem but somehow the screen is fine but alittle pink when I open it on safe mode and I do here a buzzing sound sometimes at the right corner of the computer.

by

Hannah Santhe, that sounds mole like a mother board or inverter issue than a LCD issue. I'd repalce the inverter first.

hello ,

i had the same problem , the screen is black but when I plug another screen by VGA it works ,

and the web cam works .

after 3 days searching and checking i found the problem and fixed it .

the problem is the video cable that connect the screen with the motherboard . because the screen closes and open many times , that causes the same cables are broken or corrupted .

the solution is to buy a new video cable ( before you buy, you have to specify the exact referance of the video cable ).

or , it is what i did ,

to fix the cable or cables that are broken by connecting them .

i did it it works correctly like it never happen. :)

Thanks! this is so helpful! How could you determine which cables were broken? There are lots of pins on the connectors on each side of the cable, and I don't know which one goes with which one.

Thanks a lot!!

Hi,

Try booting your laptop using optical disk or bootable usb and see if your laptop gives you boot menu if not then either your screen has gone bad or VGA is overheating. if your screen has gone bad you can test that by connecting your laptop with an external VGA LCD using VGA cable and see if your laptop is displaying.

Good Luck.

This is quite common on laptops with Nvidia or ATI graphics chips, and is normally due to repeated overheating. How old is your laptop? If it is no longer in warranty, then your repair options can be quite costly. I had a Packard Bell SB86 which after 2 years use suddenly gave me the same problem. Check out this link: www.fixyourlaptopyourself.com. It explains how you can fix a range of laptops with this type of problem yourself, and without too much hassle - unusual technique, but it worked for me.

If you haven't already, you should remove the RAM, and reseat/replace one module at a time. Faulty RAM or a faulty RAM slot can cause no video display. You don't always get a beep code to tell you this.

It Can Be Causing The CPU Or GPU On The Motherboard.... You Can Consult Your PC Or Laptop To An Technician

By The Way.... Do Not Do It By Yourself It Can Cause Electrical Shock.
