deads'ville.
my old PC CQ60-220us, thanks for full number !!!
what os? VISTA?
those are called flash codes and have meaning!
the screen never once shows TEXT or HP /Compaq logos. right?
nothing to me means just the the TEXT IS GONE
"hit ESC to enter setup" or F2,F10,,etc....
carbon14 dated by me at 2008, ? (MY HP has F1 info page shows day made, a BIOS page F1) The year mATTERS.
steps below. for dead pc. means screen dead, and BIOS keys dead.
- take the battery main out, they short, remove it ;after all you can run like that for ever on the line pack, a fact. so do so now.
- does it power on, seems yes, does it stay on? (heard and seen)
- does the fan blow< spin and not packed solid in lint?
- use flash light pointed at screen , turn PC on the use the flashlight see data now? yes, bad black lamps CCFL, ask
- beep codes or caps lock flash codes,? write them down and tell the helper what the are? its code. like Morse code.
- there are more tests. does the CD eject button work?
my wild guess, (unseen by me) is the CCFL lamps are dead.
the LCD on this PC has lamps for the back lamp that all burn out
at 20k hours of usage. (short lived, if used constantly)
other tests are: ask
- boot from free linux disk see of screen works?
- replace coin cell battery they usually don't last 10 years. 7 max.
- power pack bad and is weak, some fail weak
- keep in mind black screen failures have many causes.
- bad power, bad screen, shorts inside the pc, bad RAM.
- also the GPU chips in 2008 were bad, defective, solder ball failures. making the screen dead or very odd.
here is a black screen page.

HP is the best maker of PC.s (not custom made as I do)
but has best docs.
but they do have 1
weakness, BIOS docs and Beep/blink codes
horrible support there, due to changing the rules 20 times. or more.
HP also modified the BIOS to their needs, making generic lookups
on say Award BIOS useless.. ouch.
The older the PC the worse this gets, books covering that.
