So after waiting for a week or so, My laptop has been repaired free of charge by ASUS . They replaced the whole LCD module and it looks brand new.
A little problem though, when they replaced my display, it seems that they didn't reconnect my Left speaker and the keyboard backlit cable properly. They send me the device back and I'm unable to use the backlit keyboard and there is some crackling noise from the left speaker. I sent the device back to ASUS once again and it is the problem is repaired the following day. finally my laptop is now problem free
Thank you very much guys
