Samsung Galaxy S4 (Verizon) won't completely boot
My Samsung Galaxy S4 for Verizon has recently developed an issue where it will not turn on properly.
Steps already taken:
Plugging in a power cable results in a very warm and sometimes hot upper-mid section near the power button and camera. Only when a charger is connected with a battery, I can sometimes see the battery charging icon appear on the screen with a red LED indicator, but it goes away after 30 seconds from a cold start. The phone will not turn on at all from a hot start (I'm guessing it's overheating).
After searching for a solution online, I gathered that the power button may be stuck. I opened the back and checked continuity at the power button and its characteristics are the same as the volume buttons and good buttons as seen on power button repair videos. I also gave the button a few taps to clear any debris that may be causing the button to become closed unintentionally. The issue still persists.
The video for reference. Issue is similar but the fix will likely not work.
I'm guessing there's a short somewhere, but I don't want to go poking around just yet. Does anyone have any insight on this issue?

Steps already taken:
- Disconnected the battery, held the power button down for a minute, popping the battery back in, used a known good battery
- Attempted to boot with just a charging cable (known good) without a battery.
- Attempted to boot with a charging cable and battery.
