Desktop Hardware and Upgrade Questions

In late September of 2018 I purchased the HP Envy 34-b010 Curved All-In-One desktop.  I have been using it now for a little over a year and have thoroughly enjoyed it.  This weekend my two-year-old son climbed on my desk and caused the screen to hit a corner on the top ride side and chip the screen monitor.  This spot is now getting very hot and a couple of bars have appeared across the screen at this point.  It has also started flickering badly.  I called HP Support and found out I was out of warranty and that the best thing I could do was buy a used one on EBAY and you it for scrap  parts.  They apparently don't sell parts for this PC.  My impression of this HP went from very good to apparently a piece of junk.  I have worked with PC for over thirty years.  I have even built and sold a couple hundred of them in the late 1980s, so I can swap out this monitor.  Unfortunately, HP want allow me to purchase the monitor to replace the chipped one. I have even seen on Youtube how to replace it, but HP will not sell me the display.  Any help or ideas will be greatly appreciated.
