Quoted from ibjeepin:OK based on the fact the display PIA was replaced and now you hgave a garbled display I would also agree with everyone here its most likely one or more broken traces.
Whay did you replace the PIA in the first place? What was the issue? Garbled Screen?
Honestly, nothing was wrong...
