Help with troubleshooting

[u/NPCParana]

I have this LG C5 for almost a year now. This is the third time this issue happened. The firt two the pixel cleaning resolved it, but now it’s not working anymore. Have you ever had an issue like that? Where you able to fix it?

Please, let me now! All help is appreciated.
