Black screen and Charging Sound Constantly Repeats

Basically, I repaired a iPhone 6 with a broken screen and after putting it all back together, I tried turning it on and no luck. I then left it charging for 10 minutes and it finally vibrated and made the charging sound, but the screen was still black. Every five seconds or so it will make the charging chime sound. I tried every trick in the book such as redoing the screen replacement process, disconnecting and reconnecting the battery etc.

Could someone please help me fix this

THanks

Firstly a good practice is to always disconnect the battery before doing any type of repair on the phone, it can help prevent unwanted issues during a repair.

As for your problem, make sure that all the screen connections are secure and proper, they should all sit flat against the logic board when connected, sometimes, especially the wider one towards the back, has the tendency to get off and not connect all the way.

Be sure to make sure there is no damage on the display or the connectors. Plug the phone into a computer and open up iTunes, if it recognizes the device then you know that the phone works and the screen is what is having the issues. If you have verified that the connections are all good then you may want to try another screen to see if that helps. (If your old screen was simply cracked or something but still mostly worked you can reconnect that to test it as well. If your old screen used to work but now doesn't there's a good chance that your logic board was damaged somehow during the repair)

For your second issue with the charging, a quick thing to check it to look at the lightning connector when the phone is plugged in. Make sure that the metal part of the connector goes all the way into the phone, and the white plastic part goes right up to be flush with the phone. If it's sticking out a little then very carefully clean out the connector as there is most likely lint or other things in the connector dock that's keeping the lightning cable from making a solid connection with the pins.

Thank you for your reply. I did disconnect the battery before attempting the repair. Upon further inspection, I think the connection point for the LCD on the mainboard must be damaged. What worries me is why the phone heats up when I plug it in to charge and that it makes the charging sound every 5 seconds. Is this because of the LCD connector?

That's a bummer for sure. The lame thing about the logic board is that once it's damaged in one spot it can cause all sorts of other problems. It could be that the damage to the LCD port is causing issues with the battery/charge port as well, but I would also double check to make sure the battery didn't get any type of damage (A puncture/dent/bend, etc.) and same with the connection for the battery.

Also be sure to check the charging port, making sure that none of the pins have been bent and it is free of lint and debris.

Well, look like I have to get a new one or pay to get it fixed. The huge down side is the cost that its going to repair it. Thinking again if its worth over $300 NZD ($200 USD) to fix it..

Looks like the damaged LCD connector has caused the whole main board to malfunction as it gets hot when I try to charge it.

Thanks

I HAVE SOLVED THIS ISSUE.

I had the same issue with beeping when charger and a black screen.

I replaced an old broken screen with a new screen on my Iphone 6.

When I first replaced the screen the LCD was black and while charging the phone kept beeping every few seconds, I thought it was a faulty new screen or connectors damaged but it wasn't . I pulled out the charger cord, lifted up the screen again then unhooked the battery flex cable. I then plugged the charger back into phone with battery disconnected. The screen light came on with the Apple logo. I then disconnected the charger cable, reattached the battery flex cable then put the phone screen back down and screwed it up. I then plugged in the charger again and the phone started up. Screen and all the functions were working perfectly again. It must have reset he phone somehow.

HOPE THIS HELPS OTHER MEMBERS HERE

Does your iphone show up on Itunes? If so, your phone is likely fine. It is almost definitely that your LCD is bad. Personally, and I'll probably get flamed for this, but when doing a screen repair I never disconnect the battery. I did it once and, lo and behold, upon reconnecting the battery I fried my LCD, and had the exact same issue it sounds like you all are having.

What I'd do? Bring your screen-less phone to a repair shop, ask them very nicely to attach a new LCD to it, and see what happens. I'd put money on your phone booting right up.

Then, while it's not cheap, you spend ~$80 on getting a new LCD (bummer, but not $300 bummer) and connect a few flex cables and Bob is then indeed your uncle.

Also, why your phone's beeping when plugged in? It's trying to say "BRO, I wanna show you something, connect an LCD."

One UNLIKELY scenario is that you're not super conscienscious and you messed up some of your screws on the plate that goes over all the connectors. Don't do that. Then you're ****ed.

i found your advice very helpful buddy, i have a iphone 6 plus the LCD was completely smashed from dropping it on my kitchen floor, i removed the damaged screen with the intention to replace it with a new one and plugged the phone (without its screen) into the computer to make sure it still booted and if itues would detect it. this was a fail and the board seems to be lifeless not heating at all not even making a charging chime sound i tried booting it into DFU and that failed iTunes neither the computer picked anything up luckyly the phones insured but still have to pay access and it also takes a while. i then took the board out of the phones housing and i had my old contract 02 board still in my draw i put this in the lifeless phone and repeated my steps (well only plugged it in) computer installed apple driver software and iTunes asked me to allow access to the iPhone to be synced it also made the charging chime upon first boot but then repeated the chime ever 5 seconds is this because no LCD is attached?

Yes, this is basically your phone saying, "hey, I want to show you something, but I can't because there's no LCD screen!"

I had the same symtoms on an iphone 6s and 5s after changing screen. Black screen and beeping.

The iphone 5s got working after resetting it from itunes. I did it 3 times and then I could turn it on.

I has worked since (2 weeks). Pictures and things were still there.

The 6s was restored too but the screen is still black. Itunes recognizes it and shows battery charge and memory used. I don´t know what to do with it... And repair is so expensive.

it may be the backlight chip on your mother board is damaged while you fixing it.

sometimes it does make sound like beeping while you charging your phone but no screen show.

but that kind of problems, it can be fixed when you reconnect your battery.

seems like you have no luck, there is high chance you had damaged the

backlight chip in the mother board .

And! yes it can be fixed.
