wow photos, nobody does them , nice.
no HP PC stated, but is w10
sanyo is projection system.
NEW HDD means w10 was loaded fresh sure.
so load there software
what was the OS before the ***** of HDD< ?
sure go to sanyo and get the applications, for w10
only sanyo supports that projector no body else.
its it connected with VGA?
it only connects these ways for sure

  • RCA Type x 4 (Video, Y, Pb/Cb, Pr/Cr) composite.
  • and Mini DIN 4 pin x 1 (S-Video)
  • (VGA) HDB 15 Terminal x 1
what PC you have unstated.
nor what cables you use from proj. to PC stated.
but you do need the sanyo application from them.

ok, im reading your manual
so that screen above is not window but is sanyo only menu.

my guess is you lost the manual here

IDK now to reset this projector but it may need that too.

ok, this is very simple and basic but recovery is not.(can be impossible) we have no idea at all how the OS W7 got there, or the history of the HDD, (ever replaced) OS UPGrades? vista to 7? that LOGO is just BIOS. as is F10. so PC not dead BIOS not dead. but f11 is that dead? recovery? have your read thje manual yet, see HDD tests. that is first, no OS made runs on a dead HDD or one that is weak, smart tests failing is weak.l OS fails to boot, OS is dead, missing or corrupted or HDD is bad.that is the problem. are you backed up? that is Q1, every time to the ends of time. are you? if yes or no data personal there, or apps personal with licenses. then do the full blown HP F11 restore or try W7 startup repair, google that. if the HDD is good an never slammed. means HP recovery partition not gone or wrecked then F11 work power on , hammer F11. see? power on see if hdd test is in the BIOS my HP has that, I run that and if HDD fails, it does not lie, if that passes I run full demo linux media and run full HDD smart tests if those fail, new HDD time. there is no other way with HDD bad. HP sure does not sell media kits after 3 years, your is way way older. 10 years old it seems, even some with VISTA. read here. https://support.hp.com/us-en/product/hp-compaq-dx2390-microtower-pc/3658390/manuals

The news is all bad. The print head has died or has developed enough of an electrical fault that the machine no longer recognizes it. The machine may be saved by replacing the print head - if you can get one from HP as a service part. You would need to contact the HP help desk to find out if you can get one (have the serial number of your machine on hand) and what it would cost. Then throw the machine away and buy something else.

Possibly you printer has two ink tanks ? a small black one and a large one ? If one is empty it will not print black. The better solution is to use a q-tip and some alcohol to clean the head. If the cartridges have been replaced - possibly the new one is defective? U might also try using the head clean option in the printer properties. Additionally sometimes the contacts for the cartridge are dirty or if they have been touched with fingers they will not work, alcohol again is recommended to clean those.
