MacBook Air m1 screen flickering and blue light.

I have MacBook Air m1 2020 (A2337) .I had used at night like every other day but when the next morning, I opened the laptops, the screen showed few lines of glitches and the screen was flickering. As I tried to adjust the angle of the laptops the flickering worsened. I showed the laptop at few Apple store as well but everybody suggested to change the entire screen with panel itself. Could you please help me to come out of this. 40000 is too much to pay without any damage apple doing this
