Weak cellular and wifi signal along with proximity sensor

Hi, I repair iphones, and I recently replaced the very badly broken lcd of a customer, and all went well until the device was powered on. The proximity sensor no longer works and I have tried the strips to help with the problem and they have not worked. Also the CDMA signal was weakened, and I have tried to clean all metal to metal contact points, and now the wifi signal is weak. If I order this ->> http://www.ebay.com/itm/OEM-Iphone-4-Ver... will the signal issues be resolved?
