light on the keys of the digital air conditioner

greetings. friends 206 lights of the digital air conditioner lights are not lit, thank you for your help.

I did it, guys.

Thanks to the dismantling pictures of the heating buttons, thank you guys, the digital team did the same work. After disassembling the keypad, we have 4 more 5 star screws behind it, and if we remove them, we can take all the keys. There is no piece to be broken, there is no piece to be broken. The process is completed with 3 bottomless bulbs. My simple advice is not to be afraid, do whatever you want to do comfortably. respects
