Possible to buy replacement parts for OrnataV2?

Yoo, Is there a way to buy the membrane inside the Ornata V2? Some of my keys are starting to not work, arrows dont work, Alt left side doesnt work, and i do maintenance on it every month
I open it up, brush it up to get any dust or crumbs on it, wipe it with soft dry cloth micro fiber and close it up, and the white membrane on inside that “controls” the mapping some of them are getting “burned” duo to RGB always on, it generates heat and they burn apparently
I dont wanna buy a new keyboard as its out of my budget atm, im unemployed and still trying to figure out stuff, so if theres any replacement parts avaiable i would like to know the price
