Phone stopped working, Cant turn it on, Solid red light, weird r/g/b/w

yesterday i had a videochat call from messenger. I had this call about 2mins and then i saw i've got 8percents of battery. My phone usually drops from 8% to 2% but this is not the main problem. When i saw i had 8percents, i plug-in the charger to the wall and then plug-in the micro usb cable to the phone.

After connecting, i got red diode but isomething very weird happend to screen. On screen, there was multiple white/r/g/b (Like few on top, few on bottom but i think in the middle it was ok) strips and the aspect ratio of screen was too weird. It was mooved to right bottom corner.

The phone stopped responding so i pressed down power button for 10secs to turn off the phone. However, when i want to turn it on back, the phone was completly dead. I tried charging it from wall like 10 mins, then from computer like 30 mins but nothing worked. I left the phone charging over night about 8hours but still nothing.

//Before trying this i removed sim-card and sd-card//

I tried all variants like power +volume-up +volume-down, power +volume-up, power +volume-down, volume-up +volume-down but nothing worked. //I tried to hold it down like for 15-30secs, 20secs, 1minute, pushing it while charging but still nothing//

Phone: ZTE NX597J I bought it 4months ago so i think i must go to repair shop. However, some ideas? :D

//When i connect the phone to computer or wall, i have SOLID red light. It does not blinking// //I cant remove the battery// //The buttons like home, back and list of applications running on backround is from android so i cant make any different variations exept for power, volume-up, volume down//
