GoPro 10 Hard to start and when start bricks after 30s-1min

Hello i bought yesterday GoPro 10 black second hand. When i bought it it turned on and i tought everything is ok but BAM it's not. The device sometimes turn on like normal but after 30s-1min the touchscreen is not responding and if i turn it of it wont turn on for like a day. Sometimes looks like it turns on but the main screen is black and on the front screen says Hero 10 and stays like this for about 10 min and then it turns off. Sometimes when i insert the battery the front red light comes on and the front screen become lighter but this is the only thing it does. When i plug it to USB no red light is ON. Tried:Software update with SD card and it said Ubgrade compleate. Manage to do it like on third or fourth try. Tried to turn it on with USB,without battery,without SDcard. Nothing helped so decided to open up the case and to see for something visible but i cant see anyhing that is black or cut. Where shoud i look.
