Hi I have hp dv4t, my screen has parallel flickering lines. When I press on bottom of the screen, I get good picture (no flickering). Do you think this is cable problem or lcd screen problem.

Laptop Tech,

I havea M2000 presario that has a problem with the screen being completely gray when you boot it up. after doing some research I felt that it was the inverter. So I just replaced the inverter with a new exact model inverter and the same happens as before. The external video continues to work, and everything lse boots, but the screen stays the same gray. Help! I dont know what else I could do!

@ nimesh,

i have presario m2000 compaq it has problem to the lcd have a many colored lining but not a broken so how can i try to remove that line please

First, you have to test your laptop with an external monitor. If you have same problem on the external monitor (many colored lines), this is graphics card failure. If that’s the case, your laptop not worth fixing because the whole motherboard has to be replaced.

If the problem appears ONLY on the laptop screen and external image shows up correctly, this could be one of the following:
1. Bad connection between the video cable and motherboard or LCD screen. Try reseating the video cable on both ends.
2. Bad video cable. Try replacing the cable.
3. Bad LCD screen. Try replacing the screen.

I cannot tell which one is causing the problem without testing the laptop.

My M2000 displayed a yellow vertical line so I Purchased a New LCD screen, installed it is displaying the same yellow line that made me rip appart the old one. The supplier thinks it may be the video cable/ribbon. Of course It out puts perfect to an external moniter.

pete,

I’ve got a M2010US laptop. The screen has about a 2 inch vertical band on the left that is darker than the rest of the screen. The line between the dark and normal part is very distinct. Would this be the backlight going out, as opposed to the inverter

Nope, it’s not related to the backlight lamp or inverter board. The screen is still bright, it means the backlight lamp and inverter work properly.
In your case most likely it’s just a failing LCD screen. You’ll have to replace the screen.

I would think the inverter going out would cause the entire screen to be affected.

This is correct. When inverter or backlight fail, the entire screen goes very dark.
