TCL L55c635 TV Flickering Problem

I've had my TCL L55c635 TV for about 3 to 4 months, and I've been dealing with a persistent issue known as flickering. I've tried everything—resetting the TV, adjusting the picture settings, even updating the software—but the flickering continues. I'm at a loss for words. I'm contacting TCL in the hopes that their representatives can resolve this issue quickly and without causing further inconvenience. It's extremely infuriating to invest in a new TV only to encounter such a frustrating problem. I've done my part in the troubleshooting, and now I'm looking for TCL to step in and provide a solution. I'm not looking for reasons; I'm looking for a working television. Please don't leave me in this situation, TCL. I want this flickering problem fixed so I can fully enjoy the TV I bought in good faith. We would appreciate your prompt attention to this matter.
