Allow me to welcome you to the HP community. A very good day to you. 🙂 I understand that you require assistance regarding the computer not booting to windows and instead goes to a black screen. It will be a delight to assist you here.
Fabulous description, stupendous troubleshooting and very smart analysis of the issue before posting. Kudos to you for that. 🙂 You are a valued HP customer and I take it as a privilege to share this platform with you. 🙂
For better clarity and to assist you better I would require more information regarding this:
Did you try to connect it to another monitor and check if it works if that is an option?
Please let me know the complete model# of the PC and the operating system used.
If this computer has and HDMI port, try to connect it to a TV and check if that brings up a display.
As you’ve done complete and extensive troubleshooting and the issue is still not resolved, I would suggest that you consult a local Best Buy or Staples technician or any other technician before investing anymore on the computer. They would diagnose it correctly and tell you what the problem is. As I am not b the computer, I would be able to actually pinpoint exactly what is wrong with the machine. The video card or the screen appear to be faulty.
We first need to isolate the issue to being hardware or software related.
Please keep me posted. I will keep a watch for your reply. 🙂
Hope this helps. Let me know how this goes. I genuinely hope the issue gets resolved without hassles and the unit works great. 🙂 Please reach out for any issues and I'll be there to assist you. 🙂

The Model# is 20-b013w. It has no Video out ports. No HDMI, VGA, S-Video. Therefore having replaced the Mother board as well as the Display Panel, the only other thing I see it can be is the LTM200KT10 20.0 -LCDPanel made by Samsung. I agree, not going to spend any more money on it.
