I replaced my iPad 4 screen and now it won't

I just changed my screen on my iPad 4, during the initial repair my iPad jumped on, I didn't want to damage it so I waited for the battery to run empty. This took several days. then I still waited even longer to get to it, at least 4- 5 weeks.

Finally, I continue the repair, run into a couple of snags. The digitizer cable where the little black plastic thingy that locks the cable in broke. It's so small I could not get it to click down because it came loose. However, I laid it in there and placed the tape back and other tape to hold the cable in. It seem to be in there so I connected the screen cables back. I notice the speaker cable next to the home connector also came loose when pulling back the black tape, but I placed tape on top to hold it down as well. Then screwed the Digitizer down and it seems to be holding everything in place. I've been recharging for about a hour just to check if everything is working properly before I fix in the screen completely. The first thing I notice is that it won't turn on. And It's seems that everything is in place, but it won't turn on.

Do you think the digitizer connector is not in good enough, and would that even effect the battery? Or should I just continue to charge it overnight. because the battery has been out for about 4 to 5 weeks.

Or do you think that the little black plastic piece that is a lock for the connector on the Digitizer is the problem? And can it operate without the little black plastic lock. And can tape replace the little black plastic lock instead? These parts are so delicate, I noticed. What protocol should I do next to know if the battery is charging or that I've connected everything properly. Any suggestions to help will be greatly appreciated.

Thanks

Hi

Unfortunately I don't have an iPad schematic. The digitizer cable is not broken it's the little black plastic thing that locks it. it's really fragile. and it's on the logic board. The cable itself goes in fine and it seems snug in place as well. And my battery was completely discharged. So I'm charging it. How can I check to know if the battery is actually charging up? And does that plastic connector lock be causing the problem?

This sounds like several challenges occurred during your repair. So, let's see if I can help. The first issue that you're describe makes it sound as though the digitizer cable is broken. If that is the case, it not only will prevent you from using the touch screen, but may cause an electrical issue with the logic board. It also sounds as though several other cables and connectors may have been damaged durin the tear down. As you know, Apple uses very fine solder connections to attach these connectors to the LB and even a small amount of torque can break a connection.

You list so many issues that I'm not sure where to start. Do you have access to an iPad schematic? If so, my first recommendation would be to start checking voltages from the battery forward. To resolve/check each of your issues will require an isolation-check plan.

Best of luck!

I have this sort of issue as well but just is the small grey bit not the door but just near it. This boy covers the LCD cable connector and a little piece has broken off. — Robyn
