Screen issues

Hi all I have had this tv for 3yrs and suddenly the top left quarter is a darker colour, any ideas for a fix or is it a replacement job??

You need to give more detail on the make model of tv etc..

Have you tried a factory reset and if it's an OLED, have you tried running a panel maintenance cycle ?

Is it the same on all sources ? Freeview, apps, Blurays, consoles etc ?
