美国采购需求：透明孵化器，商用孵化器，数码孵化器，鸡蛋孵化器，在线孵化器，全自动孵化器

I recently purchased a couple of units from a store specializing in Amazon returns, but I've encountered an issue. Both devices have screens that are consistently flashing on and off, and I haven't been able to find a way to resolve it. It's quite frustrating, and I'm reaching out in hopes of getting some guidance on what steps I can take to fix this problem. Are there any troubleshooting tips or potential solutions you can suggest? I'd appreciate any insights you could provide, whether it's resetting the devices or checking specific settings. Any help would be greatly appreciated as I'm eager to get them working properly again.
