Chosen Solution

my phone screen was cracked prior to this. I dropped my phone out of my pocket and these coloured lines showed up the phone was still responsive and worked. I kept pressing down on the screen to see if I could get rid of these lines but my phone just blacked out with the coloured lines still visible. I am getting texts and people are calling me but the phone is blacked out completely.

Your LCD (the display) suffered physical damage and needs to be replaced. Typically you’ll be buying the entire display assembly (LCD + glass digitizer), which can range betwen $30 - $80 for parts only depending on where you shop and what grade/quality you choose. Please be aware that if you attempt self-repair and plan to buy the part, you will need to pay attention the grade or quality being offered, as well as the seller’s return policy since there is a risk of the part being defective.
