This phone started to show some static noise in the screen like in the posted image. At first, it happened sometimes, and would come back to normal after turning off for a long time and turning on again, but then became like that all the time. The phone apparently works, but nothing appears on the screen, even in recovery mode.

I thought about replacing the screen, but it's expensive and I'm afraid of it being another issue, like with the gpu or something not related to the screen. Has someone seen a similar problem? What do you think is happening in here?

Thanks in advance
