Touch screen works only when touching the phone or charging

Hi,

I have problem with my iPhone 5. After replacing the screen the touch works normally only when I hold it, touch the housing or when it's connected to the charger. It doesn't respond to touch when the phone lies on table and I try to operate just with the finger touching the screen.

I guess that this is some kind of problem with grounding but i'm not sure about it. Did anybody encouter this kind of problem?

The pins on the connector look perfectly fine, i've tried different battery and blowing connectors with compressed air. It has to be the screen's fault because everything works fine when I connect the old screen. Unfortunately I can't send it for replacement because i have already taken off the protectors.

If anybody has any idea what might be the problem, I would be greatful if you could tell me something about this.

Sorry for my bad english and thanks in advance.

I have experienced the same issue with many of my replacement screens in some batches... I have been unable to remedy the issue by tweaking the screens or grounding springs in any way... I do believe it's a grounding issue as ONE finger on the housing will allow the touch screen to function perfectly but when the phone is on a surface and not being held or touched otherwise, the digitizer is unresponsive. I have looked all over for an answer but the best answer, apparently, is ditch the defective display assembly!!

If the pins appear to be in good working condition, you should try your old display, to rule that out. I'm kinda thinking you have a faulty display. Which you could potentially exchange for a working one
