Horizontal Lines As Soon as Boot Up-HP Pavilion DV6
As soon as I hit my power button to boot up, my laptop screen flashes with multicolored lines across the screen. Nothing I do, even taking the battery out, rebooting, NOTHING can get me to a normal screen. Replaced the LCD screen, still have the problem. Any ideas?

The graphics is handled by the integrated graphics processor on the CPU.
If the laptop is still under warranty then get HP to fix it.
As I recall, the DV6 and DV6000 series had a known issue involving the GPU heatsink coming loose, and would cause problems exactly like you're describing.
You can google "hp dv6 recall" to read up on things yourself.
I can't find the recall list at all to see if mine is on there.
