TA-1336 Nokia G20 not turn on

The device was in service to replace the screen. After the repair it worked for a while and turned off. Doesn't respond to buttons. It takes a charge. Doesn't vibrate, there's nothing on the screen. When connecting to a computer, after 5 seconds an unknown device VID_0000&PID_0002 appears.
I took it apart - visually everything is intact, there is a small spill in the area of the headphone jack, but it’s not critical. The cable with the buttons rang - everything was intact.
I’ve never dealt with MTK - what is this unknown device? Tell me what it could be and where to dig.
 
That means he’s the drummer since you changed the display. percent solder and memory for starters.
