For some resaon I cant see anything on my laptops display. It boots up but shows me nothing on the monitor. I have included a graphic that shows that the caps and scroll keys lights are blinking and the light right above the mouse pad is also lit but not blinking. Tried hooking up a monitor to it but no help. The monitor didnt even light up during the boot process. The laptop is a HP Pabvilion dv4-1275 mx. Help

When you hook up your external monitor you usually need to use a key press combination to activate the external video port (usually VGA). Check the keyboard for an image above one of the function keys that looks like monitors side to side, usually activated by pushing the Fn key and the function button, and see if it will display to an external monitor.

Also check carefully when booting that there isn't something actually on the display but very faint as it might just be the backlighting of the lcd display.

ok turned the lights off before and during boot no backlight. As instructed I hooked the vga cable back up to the laptop before  shutdown and during the reboot process  No response from the laptop
Let's try this again, keep the lights in your room on and boot the computer, if you tilt the monitor around you might see a faint outline of the bios or windows showing that the computer is booting but it's just the lcd backlighting. Don't turn off all your lights...

As for the vga cable, shutting down and rebooting was not what I suggested, you need to look for a key combination on your computer that is used to switch between the laptops display only, the vga display only, or both.

Looking at a screen image of your keyboard from a bing search it seems like the Fn + F4 might cycle through those options.

Turn on your laptop with it plugged into an external monitor, press Fn + F4 and wait a few seconds, then try it again, after a press or two it might cycle to the VGA output and you may possibly see something on that display.

If not there's a chance the computer might not be booting properly or the internal video card needs replacing.

nothing on display no matter how I tilt it, but it does show a gray background for a second. I understood the concept of the key combination picture of this crap laptop

ok so after 30 minutes the damn laptop is now showing the screen but it has a bluish haze to it. Is it the driver?

Your rigth is the damn backlight. Is it difficult to replace the backlight? I think they may cost up to $70
The steps are probably on HP's website for the model. It usually takes some digging but I bet you can find them and do the work yourself if you don't want to spend money on someone else doing it.

Good work!
