A1822, Blank Screen After Digitizer Repair

I replaced the digitizer on my  iPad 5th Generation , A1822. When I went to test before closing it up I noticed the screen was blank and would not display anything. I could see it was slightly dark blue so not completely black but it has backlight. After multiple soft resets and multiple hard reset nothing worked. I plugged it in and removed the power supply with no difference. I did this while attempting the various two types of resets.

I reinstalled the old hardware and was shocked when the screen turned on. I proceeded to uninstall the broken hardware and reinstalled the new digitizer. The same thing occurred nothing on the screen with the screen displaying the dark green. I assume this is the back light being turned on. Each time I made sure the battery was not connected to not cause any high amp damage.

A bit confused about what to do next.

With the new screen connected try pressing the home and power buttons together for 30 to 40 seconds. If apple logo appears then let go.

I held both button for at east 20 second. Do you really think the 30 or 40 seconds makes a difference? I will do. Just asking for explanation.

Yes, some iPads need a hard reset after fitting new parts.

Thanks for responding. I just did this three times at 60 seconds each and I got nothing to display on screen. I know the new home button that came with the digitizer works because the back light responds, as in turns on back light when I push it. Thanks for the suggestion.

Leave the digitisers off and only connect the lcd and then turn it on. Just to rule out an lcd issue. I take it the battery screw was in when you were testing the last time?

@strongbow , I did remove the digitizer to rule things out. From reading and researching this looks like I failed at isolating the battery and damaged the image filter chip.
