not powering on after screen replacement, feels warm to the touch
I replace the screen and now it won't power up or turn on. Find My Phone says it is offline. The top by the camera feels warm.

You may simply have a defective replacement screen. I would try to re-install the original (presumably cracked) screen to see if the phone works normally. You can also try disconnecting the FCAM assembly to see if that causes the problem. Ultimately, you may have caused some issues on the logic board, as Daniel suggests. Let us know what you find.

I finally had time to sit down and swap back the old screen. When reassembled with the old screen the phone works. How do I get a working replacement screen?
Depending on where you got the replacement, you should be able to have it replaced under warranty. Reputable vendors like iFixit will stand behind their products.

Have you tried a hard reboot? you can do that by holding sleep and the home button for about 10 seconds.

It’s likely something major has been damaged. Could be the battery or a key component (e.g. CPU, display), but I would say the phone will either be expensive or impossible to repair.

iTunes does see my phone and tells me it is charging, but Find My Phone says it is offline. I will try opening it again and checking cables.
take the screen off and power on the phone to see if it is still getting warm, if not then its possible that the screen is defective
