Did I wreck my iPhone 8 Plus?

I used a hair dryer on my iPhone 8 Plus for about 2 minutes to loosen the silicone glue so that I could pry it open to replace the cracked screen. I got the screen half way off and used the blow dryer again on the screen for about 20 seconds and realized maybe that wasn't such a good idea. I smelled a very strong burning melting rubber plastic smell on the inside of the iPhone and now the screen won't turn on. The sound and vibration motors work fine still but I can't get the display to turn on. Does anybody have any idea what kind of damage I may have caused by using a blow dryer inside my iPhone for 20 seconds?

Using a blow dryer on a phone causes a no no. IPhones don't like blow dryers. You probably wrecked it's bowel.
