Question about HP Pavilion zv5430us (PR466UAA) PC Notebook
Hp zv5430us laptop has no video. Blank Screen. It Started out with a checkerboard pattern on screen and latched up the computer. Rebooted and it worked fine a few days. Did this a few times again until finally it went totally blank with no picture at all. Tried the external monitor 15pin video out jack. It doesn't work either. Any chance reloading original operating system and drivers could fix it or is it the motherboard?

Take the main battery out, does it run everytime on a/c line pack
power.??? this is first test of any laptop. test 1.
sure there is a chance but that is not step2..
test test to is while doing test 1, see if there is the screen prompts
in text as it did its whole life. "hit ESC key to enter setup(bios)
can you get the screen to show above,battery out?
yes, good do the ESC key, BIOS entry, .see BIOS work.
great , if yes, the the HDD is not booting windows? what?
NO, SCREEN STAYS DEAD NO MATTER WHAT.
Suspect now is the power pack. as low as $15 cost.
the pack is 19vdc, does it measure that? if not its bad. (or the pc is shorted)
at HP, the support ended. and is offically Retired
got any beep codes , or keyboard blink codes there?
does the fan run? and blow, are the vents lint free or packed.

The laptop has a built-in video card and the video RAM uses part of the main RAM.
First, re-seat the RAM modules and if the laptop still does not boot up normally then remove the RAM and get it tested at your friendly computer repair shop.
If the RAM is OK then connect an external monitor to the laptop, power up the monitor first and then the laptop. The video data should divert to the external monitor automatically, if you do not get any video image on the monitor then the video card in the laptop is faulty and a motherboard replacement is required.
A replacement motherboard may not be a cost effective solution and If it was me, I would put my money on a new laptop. I would then remove the hard disk and insert it into an USB adapter case and use it as an external USB hard drive.
