Did my screen burn ?

Hello, does any of you know what happened here ? Screen randomly got these burn patterns, after turning it off it just won't turn on again.

When plugged to a tv via HDMI the PC does appear, does that mean the screen just went and fried ?

Any idea if I can fix it myself and what might have caused it ?
