Replaced home button now grey vertical line and distorted screen

Hello all you finest folks out there.

My home button was acting up almost since new and I was putting up the replacement untill just recently it virtually stopped working. So I ordered a home button from online store somewhere in china and after studying breaking down (no pun intended) procedure I ..well...broke it down. I took it all apart and replaced a home button then carefully put it back together in reversal. I didn't forget anything because I double checked and made sure that ribbon cables aren't pinched or kinked in any way. I firmly seated all connectors and put it all together. Turned the phone on and to my huge disappointment I found a half-inch wide grey vertical line across the screen and everything is distorted. When I boot the phone I can see some shades of green (where the battery symbol should be while on charge) and when I slide finger on the home screen the phone unlocks. One can see the blurry colors - a distant reminder of icons but it feels that the image was just smashed together in to the half inch thick line. Please not that everything worked before taking it apart . Ironically the home button works as it should...and is unusually easy to push :->

Anyways now to my main question...does it sounds like a screen issue or as a logic board ? Because I wouldn't mind shelling out 50-80 for a new screen but I definitely not going to pay 200+ to replace the board.

Any suggestions?

Thank you for your time

From how you describe it it's a damaged display assembly due to a pinched cable. You will need to replace the display again. You can find the display here.

The replacement of the screen did the trick however my proximity sensor stopped working due to lighter glass. I blacked out the area of the sensor with permanent marker and everything works as it should. Also I have purchased replacement screen on eBay for $27 instead of this site for $120. They looked the same and worked the same as well.

Thank you for your help.
