Mitsubishi SRK63ZR-S Air Conditioner Fading Display Issue

I own a Mitsubishi SRK63ZR-S model air conditioner, and I've noticed that the display on the indoor unit and the remote control have lost their vibrancy. My living room doesn't receive direct sunlight. I'm perplexed by this matter, given that I've made a significant investment in one of the leading brands. I would like a solution to this problem, please. Thanks a lot.
