Sorry to hear you are having problems. I have had this same issue before with this particular model. The following solution works 90% of the time.Perform a hard reset
as the first procedure.

Blink codes are often displayed after a
user adds memory to the computer but does not seat the module properly.
The LEDs may also blink error codes if a hardware component is loose
because the computer was dropped or jarred. Some HP Notebook PCs come
with one stick of memory but have two memory slots. The problem could
be that the stick of memory or one of the memory slots has a bad
connection. The memory module
compartment on most notebooks is located on the bottom of the case. The
exact position varies by model. However, on some models, the memory
compartment is under the keyboard. See your User Guide for the exact
location of memory modules on your notebook.
Use the following steps to remove and
reseat the memory modules:
Step 1 -
Remove the electrical power
To remove all power from the computer and
prevent accidental damage to the electronic components, do the
following:
1 - Pull the retention clips away from sides
of the memory module
2 - Gently pull the module out of the memory
module slot
After reseating the memory module, replace the cover over the memory
compartment before restarting the computer
Hope this helps FiYa! If you find this solution helpful, please take a moment to leave us some feedback.
Thank You!

this sounds like the inverter in the screen. I would start by subbing the lcd screen. Then try and external monitor. video problems are difficult. don't get frustrated

First remove the battery and power cord for about a minute. Then plug back in and see if that helps. Otherwise please read the following:
LEDs near Caps Lock and Number Lock keys blink when starting notebook
The
LED lights near the Caps Lock and Num Lock keys will blink if an error
is detected during the start up process. The LEDs will blink a number of
times in a sequence and then stop. The number of blinks in the
sequence indicates what component caused an error when it was being
tested during start up.
If the LEDs stop blinking and the
computer does not start, you can press the power button again to repeat
the tests. Count the number of blinks, and use the chart to identify the
error condition.
Knowing the number of blinks is helpful when you contact an HP support agent for technical help.
