Sony Five (Expansion)

I have a Sony Five version with inserted ribbon and one terabyte of storage. But there's an issue: my brothers were playing on it, and suddenly it turned off. I don't know if it's fixable with Sony or not. I'm a man, I'll buy a PC instead; I no longer need the Sony. I'm selling it for 650, and I haven't neglected it because I'm in a hurry to sell it. The Sony is clean. Whoever wants pictures can contact me.
