Screen replaced, the device wont charge or turn on

Guys, it's driving me insane, PLZ I need help

my galaxy s9 plus screen broke, so I ordered a replacement LCD screen to replace my broken one, now by the time the screen arrived, I didn't use the phone at all, and I guess the battery was 0%.

anyway, the screen arrived, so I opened the back cover and disconnected everything out of the old screen, used the new screen and connected everything back, and I'm 100% sure that everything was connected and I didn't miss anything.

then I tried to charge the device, it won't charge via USB, wireless charging pad lights on when I place the device on it but again no response for s9+ itself, no led no nothing, I kept it on the wireless charging pad for a long time with no response at all, so I opened it up again and used my old screen this time, again tried to charge it both USB and wireless with no response for hours and hours, the next day in the morning I placed it on the wireless pad again, after 2 hours the device turned on and the battery was 12%. So I kept it charging till 100% full. turned the device off, and replaced back my new screen, tried to turn it on and again won't turn on, tried to charge and again the same problem it just won't charge or turn on, I don't understand why is this happening? BTW I did use my old screen again. (I was scared maybe the problem is in the new screen?) but yet still the same issue, the device won't turn on or charge, my connections are 100% correct

Please aI need your help, why the device won't turn on, it did once and the battery charged full, and now it just won't turn on or charge by any means

I need your help, Any Ideas? I did order a new battery tho (hope that's the problem) but it hasn't arrived yet

thank you

i would say even the new battery will not work, im guessing u dropped the phone and thats how the original screen broke. it could be the drop loosened solder pads and the motherboard is the issue

I don't think the motherboard is the issue, the phone worked fine for 3 days and was charging fine after dropping it (the screen was broken but responsive) until it ran out of charge and I didn't charge it till after I installed the new screen.

what drives me insane is that the phone worked yesterday when I installed back my old broken LCD, and made sure to charge it full, then turned it off and Installed the new one, didn't turn on, Installed back the broken original LCD, didn't work either, no LED or anything. I guessed maybe it has that issue like the note 8 when the battery drops down to 0% that the phone won't charge or turn on, but again when the phone worked I charged it 100% full

I guess I have to wait for the new battery to see how it goes

I'm really confused by this situation.

I sure it has something to do with the board their are two spots on it where you can controlled what it dose. By using stapler and touching the master to a number of to do buttons that are not labeled

I’m having the exact same problems at the minute . Other than I haven’t dropped my phone . I put it in charge one night and I woke up the next day and it was just completely unresponsive. Did a new battery fix your phone
