Display won't work on my iPhone?

The lock button for my iPhone was smashed down, so I took it apart and fixed it and when I put it back together (I put the all wires back in the same place) the display wouldn't work. Is there something I did wrong or another step I'm missing?

IPhones are extremely fragile on the inside and it is possible that you may have bent one of the pins inside, causing any number of internal problems. Ensure everything else is working, and if all else fails take it to a repair shop and see if they can fix it.

My iPhone 4s won't work at all. The front and back screen is broken. The upper left corner of the iPhone is broke, you can see through it. When you plug it in to charge it, it sometimes makes a sound. Nothing shows up. What do I do?

  • Why won't my iPhone earbuds work on my iPhone but work fine on a computer? So I have the worst luck with earbuds and it happens to be reoccurring. I have a normal iPhone 5 and I enjoy music but when I listen to my songs only one earbud will work while the other one is dead. I can go on my computer and they will both work so I was wondering why they both won't work on my phone?
  • We know that if a smartphone has more than 300 pixels per inch, it is a retina display. How much ppi it need to be a super retina display? It is said that human retina can distinguish pixels and letters in screen seem broken if ppi is below 300. If ppi is above 300, how high the ppi may be, it looks same for human eye, then why iPhone has 458 pixels in iPhone x?
  • Shattered iPhone 4s, display doesn't work but sound does? I dropped my phone, the whole front screen is shattered but I still get calls, my phone still rings and makes sound when I take screenshots but the display is completely black. When I press the home button the screen barely lights up but is still black. If I replace the front screen will it work and display again?
  • My iPhone screen won't turn the display horizontally? My phone won't turn horizontally. When I text or watch a YouTube video or basically anything else the display remains vertical even when I turn it. Why?! I've tried turning my phone on and off. I can't watch YouTube videos with a large screen or turn my phone to use the large keypad to type. It's an iPhone 5. Do any of you know how I could fix this? I'm so frustrated! It's been like this for about a week. I tried updating it and that didn't fix it.
