Do I really suck this bad? Phone screen replacement.

Hi.

I have been learning and trying to replace phone screens. The first two I have done, I have broke the screens LCD.

I simply open up the screen and disconnect the cables, when plugging them back in and turning the phone on the screen has vertical and horizontal lines everywhere. I have tried and retried and it just seems to get worse. The worse part is I'm 2 for 2.

Am I doing something wrong? I have purchased the iFixit kit and use precaution when doing screens. Maybe I'm bending the connectors, but don't know possibly how. I sometimes use the plastic opening tool to separate the connector and put it back on, or my finger. Regardless, same issue.

Do I really suck this bad? It is extremely discouraging especially because I did this twice, and cant afford to buy another screen. I have done other electronics just fine, RAM, hard drives, laptop screens, wireless cards. All no problem. Is this that difficult? Am I just that bad? Should I just give up?

If anyone can give me any advice at all that would be great. Thank you.
