Hi all, was wondering if I could get some help with my Hisense 49” Smart TV. The backlight went on it a week ago so I opened it up to see if I could work out where the problem was coming from. I noticed there was a burnt out area on the circuit board around a component that I identified as a Zener Diode (pics below).

I am hoping to fix it rather than buy a new TV, but I didn’t know whether it burnt out due to some other problem with the TV or due to the component itself malfunctioning. Is it worth just replacing the diode on its own or replacing the whole circuit board? Or even just buying a new TV???
Thanks in advance for the help.
