For a while now I’ve been having peculiar problems.The screen has a tendency to “freeze” with white lines crossing it and a slow “frosting effect slowly taking hold until the whole screen is gone. On bootup the light behind the screen illuminates it white but not with a consistent flat color. I found that altering the angle of the screen worked to some extent but peculiarly enough putting pressure on the top left corner from two points (with my hand, nothing else can hold it in place with reliable picture) gives me picture and sometimes I could have the monitor “sit” in an angle “sweet spot” that would grant me a working screen – this itself was not 100% foolproof as a little nock or nudge would cause it to fail again or sometimes it would just go. At times the screen doesn’t scramble to white and will resort to going black (not pure black) or garbled colors. The problem is erratic in its issue but always resorts to a screen not working.

I think this is the LCD screen failure. You’ll have to replace the screen.

This persisted for a month maybe more until I took it upon myself to open it up, thinking it might be the connectors or something else. Testing the connectors didn’t work, instead, it seems the only sure-fire way to get it to work is the pressure I apply on the top left, applied from behind usually with a forward push to ensure it works. Putting the bevel back in place, it now won’t fall into working condition at all – I assume this was because part of the screen casing was holding the problem at bay yet now it doesn’t, at all.

Does this require me putting my hand into my pocket for a brand new screen or can another solution be met? I don’t have a peripheral monitor to test out but I am pretty sure it isn’t a graphical issue as an outward source applied to the screen lid itself wouldn’t impact on the hardware inside the computer.

Also, just to sate my curiosity, what could be causing this?

Any help is appreciated.

I have a HP9500. Today when I turned it on, all the blue lights came on, the hard disk was accessed, and I got a surprise – a totally black screen!

Are you sure that the LCD screen was COMPLETELY black? Maybe the image was on the screen but the backlight was off?

It’s good that you fixed the laptop for now, but the problem might reoccur later. If the screen goes black, take a very close look on the screen. If you still can see a very fain image, most likely this is the inverter or backlight lamp failure.

I checked with an external monitor and the laptop was working fine – just the on-board display was black.

I scanned a bunch of sites and found out that if you remove the battery, presse the “on” button for 30 to 40 seconds, this removes any static charge. One site said to leave the external power supply plugged in, but I didn’t do that. I then reattached my battery and the dang thing powered up like there never was a problem.

I have an hp zv 6000. can i use the instructions for the dv6000 for screen inverter replacement ?

I think you can. Even though zv6000 and dv6000 are two different models, all steps for taking apart the display panel will be similar.

In Feb ‘08 I spilled coke on keyboard of HP DV6000. Removed as much as possible very quickly. Laptop will not start with ON button. Starts OK with remote. Reports battery in but not charging. All functions OK. Time has not healed my laptop.

It’s hard to tell what is causing the problem. Liquid spills are tricky to troubleshoot. It’s necessary to disassemble the laptop and take a look inside. I cannot tell what is wrong without doing that.
