Computer powers up, bit screen won't turn on.

[livinghost123]

My HP All In One screen won't turn on. The power button's light comes and the AC adapter port light comes on. I've taken the back off to see if the fans worked, and they do, but the screen won't come on. I've detached all USB devices (mouse, keyboard, etc) and I emptied the CD ROM, to restart the computer. Didn't work. What can I do? Also, I noticed that when I pressed the caps lock on my keyboard the caps light doesn't come on. Help me please.

Excuse my typos, I was in a rush and I'm on mobile.

I have the same exact problem as, http://h30434.www3.hp.com/t5/Desktop-Audio/HP-19-All-in-One-Screen-Still-Black/td-p/4985222, listed. Please help. 😞

Welcome to HP Forums, 

This is a great place to get support, find answers and tips,

Thank you for posting your query, I'll be more than glad to help you out 🙂

As I understand

No worries as I'd love to help, however, I need a few more details to provide an accurate solution:

Did you interrupt an update recently or was there an update that had been installed lately before this issue occurred?

Did you check with an alternate monitor to see if there's a display on it instead?

While I await your reply, please attempt the below steps:

Attempt a BIOS recovery
 

If the above steps work and the display turns on: Perform a hardware test to be on a safer side.
 

If the steps didn't work, use the below links for further assistance:

Alright, sorry for the late reply.

I didn't interrupt any updates, and there weren't any recently. Unfortunately, I don't have an alternative monitor to check the display on, currently.

I've attempted the steps you provided several times, but to no avail. It should be noted though, my computer never restarted once I reached the final step. I noticed that the guides were for Windows 8, but I have Windows 10, maybe that's why it didn't go to well for me.

Also, this may be irrelevant, but a few months back, I had to replace my hard drive after I got a "Blue Screen of Death," that I was told occurred because of the Windows 10 update.

Thank-you for replying. 🙂

You're welcome. 🙂

As @Riddle_Decipher is out of the office today, I'm replying to you. I appreciate the steps you have performed and have certainly done a good job.

Though the steps from the previous links were for Win8, they would still work for Win10 too. 

I would like to mention is that if the issue still persists and if the PC does not boot to BIOS then it indicates towards a hardware failure. I won't say a hard drive failure because the PC should still boot to BIOS if there's a hardware failure. 

I recommend you to reach out to HP phone support to explore the hardware service options for the PC. 

Please do reach out to us for any questions you may have. Cheers! 🙂

Thank you very much, I guess there's no way around a repair. Thanks again for the help. 🙂
