Not enough information to be able to specify the remaining life of the matrix, or to ensure that it will soon die.
Personally, I would fire the options / brightness / contrast one hundred percent to see after a quarter of an hour if it dies faster. If it holds its values stably, does not dim, does not sizzle and does not smell like a wet rat, it will play and dance for a long time. For me, the stripes extinguished the flame of life in the same model more than 3 years after its appearance.
Currently, after replacing the matrix, a black spot has recently appeared, which illuminates with clear, bright colors, but after cooling down, it disappears
