Freezes when screen locked.

Hello everyone.

A customer delivered me this Samsung Galaxy S4 LTE (GT-I9505).

The device works perfectly, but as soon as you lock it, and wait a few seconds, you can't unlock it anymore. Screen stays black, and the only way to get it started again is by removing the battery. Then it keeps on working perfectly, apps, games, everything is fine, as long as you don't lock it (by pressing powerbutton or auto lock)

Either then it crashes or restarts.

Things i've done already:

- Soft reset

- Hard reset + cache wiped

- fresh stock rom installed with Odin.

Problem still persists.

I'm 100% sure that this is a hardware issue, but then again, with over a 1000 components inside, wich one would cause it?

Anyone had this same problem and found a way to fix this would be a GREAT help.

Kind regards,
