I hope this message finds you well. I've noticed an issue with the screens we've received, as they are displaying prominent white lines across the surface. This is impacting their overall functionality and user experience, and I would like to address this situation as soon as possible. Could you please provide insights on whether this is a known issue or a defect in the batch? Additionally, I'd appreciate any guidance on how to resolve it, whether through potential repairs or replacements. Your prompt attention to this matter would be greatly appreciated, as it affects our ongoing operations. Thank you!
