Hello dear helpers!!! I really appritiate your WORK!!! Recently I / my laptop got into trouble with it's LCD display... It began with exactly half of the display (right side). the picture on that half began to (let's say) shimmer a little bit. It was about 4 weeks ago, I first noticed that. This occurs every once in a while since then. And three days ago my computer was overheating once during a game. It switched of automatically. I left it for about 30 min to cool down . When i started it again, i noticed a tiny (1 or maybe 2 pixels in width) white line through the whole display vertically. Yesterday it got two new "friends", about 1 inch between each. so there are 3 now. Any Idea what's going on??? Is this possible to solve?
I had the same happen to me.. it started with one white vertical line.. then got the whole rainbow (red, green, blue).. Solution: Try connecting an external monitor.. if there is no problems, then it's not the video card or chipset.. it's going to be the lcd.. you can get it on ebay for about $200.. hope this helps..

You should try this monitor and the video cable with another PC to see if it works OK, or try this laptop with another monitor to see which one is not working, I have a feeling something has changed in the laptop setup.
Please post back what you find.
Have you dismantled this recently? If so, check that the video cable from the screen to the motherboard is firmly in its socket.
If you have not, then try to connect it to an external monitor and see if the problem goes away, that will eliminate the graphics chip if it does. You then need to look at the screen itself, checking all connections are tight. Normally with a white screen, the backlight is working and I would think the inverter is too (although not definate), and it would apppear to be the connection between the mobo and screen.
If it still persists, there is a much deeper issue with the motherboard
Kindly check what are the latest installation you installed from your system or you can reboot your computer then press F8 to start the safe mode operation of your system then reinstall the latest software or driver utility software you install in your system that made your system work abnormal.
Yes, the connector next to the speaker connector is for the power adapter. It's different from the speaker plug so you can't put it in the wrong place. Hopefully you got the right power adapter with the monitor.
Here's the page at HP's site where you can download the User's Guide for this monitor. Hope this helps.
Sometimes intemittant video can be caused by a couple differnet things on a portable system.
1. Bad ground. Some LCD are grounded to the chassis through the hinges. If the screws for the hinges become loose, the ground becomes intermittant. So tighten any screws for the LCD hinges.
2. Sometimes the LCD video cable connection to the video card becomes loose from heat expansion. So see if you can find the service manual on the HP web site, and see how to reseat the video cable (should be listed under the LCD install/removal)
3. If neither of those resolve, then you may have a problem with the LCD itself or the cable that goes to the video card as hte cable goes thru the hinge assembly.
