Hello,
the hp laptop's screen has stopped functioning recently, so that every time i turn it on, all the fans spin and the lights come on, but the screen is completely blank not even showing the bios. all the lights turn on and there are 2 sets of 5 small white lights that blink in 3 second intervals (one on the left of the keyboard, one on the top of the keypad, right to the altec lansing sign)

 
It could be anyone of these issues

1.loose cabling for the monitor (trouble shoot by using external screen)

2.bios issue, fix by clear/download latest bios

2.5 driver issue, hard to implement fix

3.heat issue, solve by opening it up and making sure fans/heatsink clear of dust and gpu/cpu is making good contact with heatsink

4.broken lcd (either inverter or the cft), hard to troubleshoot without buying replacement screen/inverter

5. motherboard traces damaged, hard to diagnose (try using a hair dryer/heatgun on area around gpu)

6. dead monitor cable (very hard to determine)

7.dead gpu (after all above fixes have been gone through)
