help with iphone 6 screen issue!

[andrew646]

Hello!

I have an iphone 6 with the latest update installed currently.

Sometimes while using, doesnt have to be with any apps in use or just sitting there with the screen on, the screen will fade out until its completely black. Once you hit the home button a few times it will come back on though. And no, im not meaning it goes to sleep lol. I can be actively using it and it will do this.

Also... sometimes when i press the home button or power button to wake it, it will come on but the screen will be all fuzzy, similar to white noise or static on old tv's.

I have tried..
Screen replacement
Updating to latest ios
Factory reset.

Has anyone heard of any issue like this or how it was fixed or if it COULD be fixed?

Any and all help would be awesome, thanks!

This case is strange. If you've already replaced the screen, then it should have fixed it. It seems to me that this needs to be inspected by a tech as it may be something else on the board that's causing it.

A static-y screen is not a good sign. The screen driver circuit is fairly simple, it provides voltages to the backlight and LCD and a serial communication coming directly from the CPU is driving the pixels. Normally screen issues are no backlight or no LCD. A static screen indicates a junk signal coming though the data lines.

You should have this looked at by an experienced micro-soldering tech but I would suspect the phone may not be fixable.
