How would I fix my flickering screen?

Hello

I've had my iPhone 4 for a while and not long ago I woke up and my screen starting flickering (mainly white). I can't see it acess my iPhone. I can hear it though, if I unlock it I hear the unlock sound so it's not totally broken. The screen is also pretty badly cracked. So what would be the problem? The LCD? The battery? How would I go about fixing it? What part(s) should I buy? Also I tried restoring so it's not software.

Other info:

- it could've gotten water damaged, I mean there's no way I could tell waters everywhere in life

-everything functions fine (touch abilities, sound, buttons, etc.)

-I have used a 3rd party iPhone repair shop to replace the screen but i don't think they did it, the problem occurred after more than 6 months of the repair

Answer this question I have this problem too

Is this a good question?

It very well might not be fault of a non-authorised repair shop. They might have paid a high price to get a fine part, which turns out to be shoddy. You may have better luck with a second replacement.

You might have a LCD Cable that was jarred loose. Or, the LCD could be faulty. You should open it and try reseating the cable.
