Generally speaking, for the bright spots on the screen, if they are quality problems during the warranty period, alien brands will provide free maintenance services. Screen highlights may be the quality problems of the screen itself, such as pixel burning or screen hardware failure. In this case, you can contact alien customer service, describe your problem in detail, and provide relevant information such as product serial number or purchase certificate to get more accurate answers and solutions.
However, if the bright spot on the screen is caused by man-made damage, accident or improper use, it may not be covered by the standard warranty. In this case, you may have to pay extra to fix the screen problem.
Please note that the above answers are based on my understanding of alien brands and general assumptions, and the specific warranty policies may vary according to regions and product models. I suggest you consult the alien brand directly or refer to its warranty information in official website to get a more accurate and detailed answer.
