Samsung galaxy s7 wont boot to home screen


Hello,

I have samsung galaxy s7. When i connect my power supply to mother board with 3,8V it boots to second logo and stops there. When i connect power supply with 4V it boots to first logo then turn off and my power supply start bips like there is a short. PMU is slightly hot but i think is normal. Does someone have an idea what is wrong? Thank you for your answers.
