Answer to "Lcd not working properly after screen assembly replacement?"I have had the same plaid/checker board. even split between partial connection and damaged connectors on the mother board.

Answer to "Replaced Screen now it turns on but screen is only dark black."+1 to the possible defective screen. Also it is entirely possible there was other damage done to the phone when the screen got broke. I have had a overly high failure rate on the 5 line of iphones. Esp the 5c.

Do not lie to them tell them how many repairs you did this way and how many of those required the lcd in the end. The customer will always take the risk and accept the potential for full assembly replacement 99% of the time any how. Truth is and i do not care how many repair techs say other wise no one can do glass only repairs with zero failures. To many variables in how good the glue job is under the lcd. A void under the lcd in the wrong place will result in a busted lcd with no fault on the part of the tech. I had a s4 going smooth as silk got half way done and lcd broke about 3/4 the way down do to a void in the glue behind the lcd. Yeh the customer was upset but understood that there...
