Stupid question. Did you charge the battery? It’s possible that when you put the new screen on and found out that it was bad, you just took the part off and forgot to turn off the phone. That would explain why the phone didn’t turn on. If that’s not the case then I’m not sure what happened. Heating the battery should not cause problems however did you disconnect the battery first before heating it up? The only other thing I can think of is that at some point during the repair something on the logic board got shorted out causing the device to not power on.
