Touch stops will stop working occasionally

So I got this iPhone 5S in today that I am completely stumped on, the touch will work perfect and then suddenly it will stop responding until I smack it to the palm of my hand gently and it will immediately start working again. I have tried 3 different LCD assembly's all original apple parts and tested for functionality on another device. The same thing happens. Any ideas?

Have tried a reset fixes 99.9% of all iphone problems.


Yes, I have reset the phone on the phone, I have not tried iTunes yet, would that make a difference?


Also, when the touch stops working it won't start working until I hit it in to the palm of my hand almost like there is a short in the LCD but it is not the LCD'S


What about the connection on the motherboard.


And no, you have a physical problem not software. itunes wouldent help

Most probably touch IC failure.

It (they) will need replacing or reballing.

Otherwise touch failure that's not due to a bad screen can be due to a number of things on your logic board: the connector, some caps or filters leading to the touch ICs, or the touch ICs themselves.

This is repairable but not a DYI project nor for a tech not trained at Microsoldering.

yes sounds like touch ic, there are also small ic's near the connector and if knocked during fitting the screen can also give this issue.

I have absolutely no idea if this can be fixed or not but I think

I have found my problem. As suspected by me and many of you I believe I have some logic board damage. I have included a picture of the logic board in my 5S next to another fully functioning 5S logic board. After removing the black sticker that goes around the connectors there is a visible difference between the two. The one having the touch issue looks a greenish rainbow color. Note that the board has not sustained any water damage. After removing the screens bracket and tinkering with that a bit when the board stops responding to touch I can tap the board near the touch ic controller and it will immediately start working again Until it stops working. I have not noticed a pattern per say at all and even if I try I can't get the touch to turn off again once it's back on other than waiting for it to stop so I can't figure out what causes it to stop. Anyway this is probably very confusing for most of you and I am not expecting a fix, but I am kind of wondering what could have caused this damage pictured? I am positive it is somewhat related.
