I seriously need help, I don’t have much for new phones. I have an iPhone 6 and all of a sudden I saw a quarter of my phone went black and the other part had multi-coloured lines. It then went black screen and now I have a feeling it’s gone forever. If there is a fix how much would you average it, thank you so much!
Based on your description, it sounds like the LCD is defective. You can find a good quality replacement here on iFixit. This would be the repair guide to follow.
