xperia xz premium sudden death

[dacxx_]

hi,

so my phone suddenly died and i tried to force restart by pressing vol up and power button but nothing happened. when i try to press it, there is no vibration at all from the phone and the led blinked with a yellow/orange light. everything was fine before that happened and the battery percentage also still high. Can anyone help me to fix it? it means alot to me 

thank you
