Red display error

[mukaram1]

I have note 20 5G 

It is showing red instead of black.

Slightly Red colour in place of black 

I tried resetting by device but it's not fixed...

In the *#0*# menu when I click on black it shows light red colour

It's very annoying 

Please help me to fix it..

Also colours of screen changes on changing brightness....
