It's the lcd video cable. The wires are damaged so when you move it up and down at some point they touch and at other times they don't.

Replace the cable and you're good to go.

HP Compaq nx9020 scrambles the screen on start


"scrambles"? Has the Laptop been cleaned? Fan and vents? Overheating? You may have to open the unit to clean, also replace the CPU and GPU Thermal Paste, if the Graphics Adapter hasen't been damaged by overheating that may help. It may be Done. Try booting to Safe Mode with Networking, that will apply the generic driver. Perhaps the driver is incorrect or corrupt. post results.

Laptop has black screen on startup. what do i do to repair this.


I have a similar problem:


I have a Compaq Presario SR2010NX desktop computer. Recently, very occasionally, the computer would freeze and the screen would scramble. It almost looks like someone chopped up the picture on the screen. Then we would have to manually shut down the computer and restart. It would always work fine afterwards.

Yesterday the computer did it again. It restarted fine but when my boyfriend tried to install a new mouse the computer froze again and the screen went scrambled. Well this time it did not start back up. I tried to unplug the computer from the wall and restart but that got me to the COMPAQ screen and then the computer froze again and the word compaq was doubled all the way down the screen. We continued to try to start it in PC recovery but it would get the the program and freeze. I actually got it to run once but I couldn't see what it was doing because the screen was scrambled.

Now we have restarted it so many times that it will start up, light turns green, and stays green. The computer sounds like its starting up and it seems louder than normal. The computer doesn't do anything and the screen is black. The lights on the keyboard do not turn on but the light in the mouse does. The CD drive will light up and run as well but nothing happens after that. I can't see the cursor and the keyboard does not work.

I opened the computer up, cleaned the dust off, tried to re-install my old RAM and that did not work either. I disconnected the CD drive but that did not work. Tried to start the computer with nothing plugged in except mouse, keyboard and monitor and that did not work.
I don't know what to do! Help!

if the screen is the same scramble at start up as in desktop screen then the lcd panel is at fault ,the videocard in from memory on the motherboard

there are chips along the top of the lcd inside the case,some times they fail and do the same scramble result,replace lcd panel and away you go,
