iPhone 5c screen completely unresponsive

Okay so my iPhone 5c touch started acting up a few weeks back, it would stop working for a few moments, you lock it wait a minute and it would suddenly work again. Fast forward a few days I updated the software and shortly after the touch screen became 100% unresponsive.

I've done all the "reset, restore" instructions I could find and nothing helped, I thought maybe I needed a new screen so I ordered a new display kit online.

It came in today and I very carefully took everything apart and installed the new screen, it powered on perfectly fine, the picture is perfect but the screen is still completely unresponsive!

I've taken it apart again several times to check connections and such and I can't see any reason it shouldn't be working.

Does anyone know how to fix this?!

Is there any way I can confirm that it's a logic board issue that would require that kind of repair without having to bring it in some where?

The iPhone 5C is prone to all kinds of logic board issues, particularly the loss of touch, caused by micro-fractures. On the iPhone 6Plus, we call this Touch Disease. However, the 5C can also suffer this due to the weaker, plastic housing. The same flexing issues can affect the 5C.

Beyond checking the condition of the connectors on the logic board, I would have to assume that the Touch IC's need to be replaced on your device. This is requires micro-soldering and is not DIY. If you would like to fix your device, you will need to find an experienced repair shop that does micro-soldering repairs.

I've been having a weird issue lately with 5C with touch issues. I found out all of them ended up being caused by the digitizer connector being worn out, damaged or dirty.

It always ends up being the ones that have been repaired before (heaps of times) from another shop, no screen metal plate allowing the screen cables to unplug after the phone gets dropped.

Had this about 3-4 times. Sometimes digitizer connector needs to be replaced.

If the phone is one that has not had screen replaced before the screens will work with no touch issues (when testing with multiple screens to find a working one).

If the connectors aren't damaged, as @benjamen50 suggests then I would have to assume it is a board problem.
