I have an HP Pavilion DV7-3162NR product # WA801UA. When I boot it up I can hear the fan running & all of the lights on the front except the caps lock is lit up, even the wireless & it is an amber color. I hooked it up to an external monitor & still no display. The is no light codes as listed on HP website. Any ideas?

Did the BIOS screen appear on bootup?  If it didn't then you possibly have a graphics chip failure.  Retest connected to external monitor and reboot.

Is there a blinking cursor in the upper left? It can look like a blank monitor sometimes.

You might check the memory to make sure it is seated properly, and the hard drive to make sure it is seated properly.

Make sure there is no USB drive plugged in.  If there is and it is not bootable, that may also block the computer from starting.

Have you tried holding the del or esc key while powering up to see if  BIOS screen will come up?

If the display chipset has failed and is blocking the screen and external ports from working...then the laptop may be done.

The DV series from HP is notorious for bad cooling that eventually kills the mobo.

Your symptoms look like that. Try to get your laptop to a repair shop and see if they can do a reflow. That will give you a few more months, but it's time to look for a replacement.

You can do it yourself, but it's labor intensive and you risk killing it permanently.
Here's a guide for that: http://hardforum.com/showthread.php?t=1531323

Before putting the motherboard in an oven have you tried removing and reseating the RAM?
