Touchscreen unresponsive after screen replacement.
A few months ago i dropped my Iphone and the screen and lcd broke, also the frame got a bit bent on the top. I got a guy in inonesia to replace the screen (digitizer) but he did not want to bend the frame back in place in case the motherboard would break. He also removed the metal frame on top of the lcd,digitizer and camera flex cable. The phone seemed to work just fine for about a week, but then one day the touchscreen started failing, I did a hard reset, and the touch screen started working again for a couple of minutes, but then it was unresponsive again, and after that i could not make it work at all, also the screen would not turn on. Because this had already happened my dad bent the frame a little to its original state and tried to put the screen apart and then put it back together to see if it wanted to atleast turn on, so it did. but only for a couple of hours because when he tried to turn it on the day after it wasnt turning on at all again. (we tried to unplug the cables and plug them back in again but it made no difference).
I tried myself to do the same thing a week ago, but the screen wouldnt turn on. but when i charged the phone it made "boink" noises and the pc recognized it, so I updated the phone, and tried to format it, but still there was no picture. I concluded that i had gotten a bad screen and decided to buy another one, Yesterday I replaced all the parts to the new screen, reseated the battery and put everything back together, and now the phone turns on to the 'slide to set up' front, but my touchscreen does not work at all.
i can't really find anything that helps me with the problem on google, i have tried hard reset, to reseat all the cables and the battery, but the touchscreen still doesnt respond. Also wanted to add that only the digitizer cable and the home button cable makes a clicking sound when i snap it on. Also, it doesnt seem to be any water damage to the phone.
does anyone have any ideas how to make the touchscreen work?
I'm sorry for the long post, just really frustrated and wanted to explain as much as possible :)!
