Note: Clearing the alignment peg should not be difficult if you open the cover from the other side first as shown in my edit.

I found this step very difficult. It required a lot of pressure to push the peg through. Make sure you push the peg from the side shown or it can tear the LED cable shown under the tip of the torx driver.

Your best bet would be to purchase a unit being sold “for parts” or contact the company. They may be willing to send you a replacement, or sell you one.

I would not recommend a heat gun. The plastic is easy to melt. A hairdryer would be sufficient if you choose to apply heat. I did not find the need to apply heat at all though, and the front panel came loose with gentle pressure.

Update: I wanted to let people know that I was shipped a Motherboard from the company when I called them about the issue. Replacing the motherboard (not the Display panel) resolved my 'no display' issue.
