Before you start messing around flashing the bios reseat the LVDS screen cables.If the gold pins are tarnished clean them with a pencil eraser.Remove the RAM as well,and clean the pins also try known good working RAM.

If you are going to flash the bios you must choose the correct one ,there are 5 different ones listed at HP support , ROM Family SSID 2B06/2B08/2B13/2B0D/2B21.

Jumper 4) FDO should unlock the flash descriptor,you can`t flash the full bios without this unlocked.

2) BOOT BLOCK and 3) BOOT WRITE should also be jumpered.

Flash the wrong bios and it`ll be bricked.If you have an SPI programmer i highly recommend that you make a backup of the bios first,and post it here.
