@ Lanny,

How do you replace the LCD cable in an HP Pavilion dv4-1220us. I presume I need to start with the above procedure of replacing the screen. What are additional steps to get at connection to base of computer

You’ll have to remove the top cover assembly as it explained in STEPS 1-15 in this HP Pavilion dv4 disassembly guide.
After the top cover removed, you can access and unplug the LCD cable from the motherboard.

When inverter fails, the backlight will not work BUT you still should have a very dim image on the screen. Take a closer look. If there is NO image at all, not even dim image, most likely the problem is not related to the inverter board. Also, test your laptop external video. Even if laptop screen, inverter fail, the laptop still should output video externally. Does external video work?]]> In reply to Fritz.

@ Fritz,

Does the HP dv8t Quad Core model have a screen inverter? I have replace my ram (both modules) and the motherboard and the screen is still blank. Power and hard drive lights come on. Sort’ta at a loss, don’t want to write the laptop off its still in good shape.

I have a pavilion dv4-1509tx with a lcd screen and not the one with the inverter.

I had disassembled my laptop to clean the cpu fan as i had heating issues. The last step was removing the motherboard which wasn’t mentioned in your guide which turned out that there are two screws securing a port (i don’t know what port it is? a flat port). The reason im here on this page is that after i assembled my laptop, when i tilt the screen at different angles the whites turn purple (when i open the screen the colors are ok and then if i pull it a little bit towards my self or if i shake the screen, the whites turn purple). I thought that maybe the video jack wasn’t in place or was loose, so I re-disassembled and assembled it, but with no luck. What could be the problem? The video cable itself of something else? If its the video cable then where could i order it and any serials or models of it?

Emily,

I just replaced my broken screen(I have the version with the CCFL backlight) and as far as I can tell, I did everything correctly according to your instructions. When I go to start up my screen, all I get is a black screen. You can tell the backlight is on, the screen is just blank. Do you have any ideas what I may have done wrong before I attempt to disassemble it again?

It’s possible the video cable not seated correctly on the back of the screen. Try reconnecting the cable.

Problem is the backlight is out I think….. Well it had been displaying complete blackness until my friend took the whole thing apart and put it back together again! Lol now i can see that the screen is displaying but its not lit up so its hardly visible. What do you suppose needs replaced on it?
