Ziyadul you did not tell us if anything happened to the phone prior to. Anyhow, there was a service notice on the S5 regarding "How to check Capacitance impedance to analyze 'No power' issue of S5" so check on this first.
Note: The Impedance of Capacitance (Either C903 or C948) must NOT be shorted.
Remove the shield can in the yellow box (located near LCD connector as shown below).
Measure the Impedance value of each capacitance in the yellow box as shown below.
If either capacitance is shorted, replace it to the new one.
Remember that this must be done with a capacitance meter.
For anything else proceeds with troubleshooting according to the manual.

What sort of phone is it?

It is a Samsung Galaxy S5, model number SM-G900F. The same model that I'm currently using right now. Sounds like the power management chip is busted if it's really heating up a lot at the top part of the screen / near rear camera.
