This can be sign of GPU or LCD failure. However I would first check all connections between the motherboard and LCD panel inside the unit are all present and connected correctly.

there are several reasons why picture of crt monitors did not display good picture. if your monitor had horizontal line at the center of the screen?...the faulty is in the vertical deflection, check the vertical oscillator also the fusible resistors & capacitors around that section. if there had vertical line at the center of the screen?..check the horizontal deflection, horizontal output transistor also check the YOKE.

My computer screen started to show horizontal lines a long time ago. It's not the computer, it's the screen because I had this screen on my computer and went to buy a new one. About 2 to 4 years later


Hr scello try to renew or install the screen card driver.

I think your pc is missing the driver.
When the driver is not correct or missing, you get a bad picture on your screen.

Visit the pc or graphic cards homepage insearch for the screen driver.

Good luck

When watching movies on my computer, I am getting a weird line through the middle of the screen at times, also, when things are moving on screen faster, more lines seem to show. I guess they don't really...


i think your vertical IC ( if vertical lines are shown) / horizontal IC ( if horizontal lines are shown) of your monitor has damaged. you may contact a mechanic and change the corresponding IC

Horizontal lines on screen HPCQ509


Lines on the screen are usually caused by a hardware malfunction in either the lcd, lcd cable or the GPU.

Do the lines appear immediately after power up the computer? Or only when Windows starts?

Can you hook the laptop up to an external monitor to test?

How long have you owned this laptop?

Black screen with horizontal green lines


Hello yoyoxide.


from my experience can be something related with the video card. I recommend you the followig (Hardware diagnostics):

-Look for one of the discs that came with your computer, it should say (Drivers & utilities).
-Boot from the CD. If you don't know how to do it do the following:
1.Insert the Drivers&Utilities Disk.
2.Restart teh computer.
3. When you get the Dell logo, press F12
4.Select Boot from CD/CDRW-DVD (something like that).
-You will get a prompt to run the diagnosics.
-Just follow the wizard
-I recommend you to run diagnostics for everything.
-You will see if you have any problems with your hardware.

It seems that you have a pretty new laptop, so probably it's under warranty.

Horizontal lines on Screen


Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!
