Hpuser2020:  any luck with screen problem? I have also replace inverter and still same problem. LCD is working since I can see really dim images also external monitor works fine. Any solution? anyone?

Same problem. It's been happening for the last few days and I've usually been able to get it started somehow, but yesterday it didn't. I tried the whole battery thing and it didn't work. The HP logo in the back lights up just fine, though.

Is there anything else someone can suggest? Unfortunately sending it off to be fixed isn't an option, at least not for the next two months.

Oh, and it's probably not the motherboard; I had it replaced a few weeks ago.

Hello roxans6.  

I want to repeat your issue to make sure I understand.  When you turn on the notebook it lights up and the fans spin.  However, nothing ever shows up on the screen.  Is this correct?

Have you tried performing a hard reset?  This is similar to what you mentioned about "removing the battery" but it needs to be done in specific steps.  Try the following.

1. Power down the notebook.
2. Remove battery and AC power.
3. Press and hold power button for 15-20 seconds three times.
4. Replace battery and AC power.
5. Verify whether the issue is resolved or not and post the result.

I will await the results of this reset.  I hope you have a great day!

hi there,

 I got HP Notebook, I just left my notebook about half an hour and come back, the screen didnt come on, I tried taking battery out and in, pressing the power button, and when I turned it on lights came on and asked me whether windows to start on normal or safe mode, and chose normal then windows wouldn't start, it is all black screen and I can hear windows loading, but black screen, then I tried to put it on safe mode, and windows started on safe mode , but soon as I turned it to normal windows, wouldn't start, so Please let me what should I do, anything I can do, or I should take it to pc repair centers.

Hello bulldog43.  

So, you're able to boot into Windows when using Safe Mode but not normal mode?  To me this implies that the issue is software related.  The most likely cause is the video card driver.  To begin I would suggest trying to reinstall your video card's driver in Safe Mode.  

I will be happy to locate this software for you and type out some instructions.  I will need your product number for this.  Take a look at this document to see where to locate your product number.

I will keep an eye out for your reply.  I hope you have a great day!
