德国采购需求：视频游戏机、游戏棒、手持游戏机、电视游戏盒、游戏操纵杆、PS4 游戏控制器

I recently purchased a game stick from the TikTok Shop, and I've been experiencing some issues with it. After connecting it to my TV, the title screen appears for a few seconds, but then the display goes black. I've tried disconnecting and reconnecting the charger, but unfortunately, the problem persists. Could you please help me troubleshoot this issue? I'm not sure if it's a hardware malfunction or if there's a specific step I'm overlooking. Any guidance or support would be greatly appreciated, as I'm eager to enjoy my new game stick without any further complications. Thank you!
