iPhone won’t boot and shows pixelated Apple logo

Hello, I am having a bit of a trouble with my iPhone 7. A few weeks ago, the phone was working perfectly until it began to shut down randomly. A soft reset would resolve the issue but the phone began to shut off randomly even more. I have tried to restore it many times using iTunes or on the iPhone but that did not fix anything. I have changed the battery which fixed the issue for a day and then the same problem. Now my iPhone won’t even boot after a soft reset. It sometimes shows the Apple logo with a pixelated screen and then go back to a black screen. It does show perfectly however the “plug in you iPhone” sign when you don’t have any charge left. Does anyone know what might be causing this issue ? It is pretty annoying. Thanks for your help. :)

Looks like a logic board issue you should take it to a microsolderer

That’s a board issue which is most cases on GPU line. Are you a technician? if you’re look on GPU line and do measurement.
