My Huawei MateBook D16 Has Yellow Screen Tint After 6 Months

Hello. I purchased the Huawei MateBook D16 about six months ago, and I’m already experiencing serious display issues. There's a yellow tint appearing on the lower left side of the screen, especially visible on dark backgrounds. I’m not sure if this is due to a burned-out LED or another hardware issue, but either way, it's unacceptable for a laptop in this price range.

Previously, I contacted customer service about a cosmetic defect on the upper right corner of the screen right out of the box, and they did nothing. Now that I have a more serious problem affecting usability, I still don’t know if it’s covered under warranty or how to proceed.

I paid nearly ₺50,000 for this device, expecting premium quality and proper support. Instead, I got a machine with build defects and no technical help. Huawei, I need urgent technical support for this issue. Please contact me directly and take responsibility for the product you sold.
