奥地利采购需求：AF400S ARGB，带 RGB 的 PC 机箱，ATX 中塔，钢化玻璃，气流设计，游戏配置

I'm reaching out regarding a device I recently purchased. I'm having some trouble with getting the screen to power on. I've followed the initial setup instructions, but it seems like I might be missing a step or two. Could you provide some guidance on the proper way to turn on the screen? Additionally, if there are any troubleshooting tips or common issues related to the screen activation that I should be aware of, that would be super helpful. I'm eager to get this device up and running so I can start using it effectively. Thanks in advance for your assistance!
