My iphone 4 screen went black and won't turn on

Omg,thanks so much,I was so nervous about it not gonna be able to work,was my only phone and used for years,remembering like 80%battery like 30 minute ago when I first found out it didn't work.Press Power button didn't work.Press Home didn't work,decide to search it up on my computer and found this tried pressing them both together It worked fine,thanks so much,mind explain the mechanism behind this?Was wandering why this would work while single didn't work.

I had the same for the second time today... no way to turn it on !! it was 63% loaded and on my desktop without activity (on the iphone ;- ).

tha only way to turn it on is to unscrew the two scren at the bottom, remove the back cover then unscrew a screw on the bottom left, close to the black battery, then you unplug the plug, wait a few second, plug it agin and screw.

Then turn it on ! it works twice ... then your iphone will first set as 1st of january ... but later recover everything date, time ... then i had a prompt with "imap.gmail.com" not recognised (written in french, i am french !), then i had a "dataaccessd" screen asking to accept the Equifax Secure Certificate Authority as non thrusted ... don't know what it is but asnwer YES and ACCEPT then iphone is fully operational ... until next crash !

Uhhh, don't take the phone apart, you will void the warranty and have to pay more than you would expect if you had to get it replaced through Apple.

Hold down the power button and home button at the same time to see if it will turn on.

If not, hold them both down while it is plugged in to the computer to see if it will respond.

If still nothing, you may need to get it replaced

Mine is more than 2 years old ... Apple will laugh me if i come to the support and ask for a replacement ... (I already got the same answer with my iMac two years ago while it was only 3 month old and get HDD crash because i didn't buy their extra-waranty). If your iphone is till under waranty, off course ask the support first otherwise do it yourself ! you will earn time and money. there is nothing as easy as the iphone to change spare parts even if it looks hard at first.

Fred,

I don't see a plug, only a ribbon type thing attached to battery. How do I un plug?

Look at the bottom left, there is a screw with a ribbon connecting the battery to the motherboard, unscrew it, disconnect the battery, wait for a minute, then plug again, screw and turn it on. It may have loose the time and date but should turn on again...

Absolutely worked! Was so nervous (a non-techie me) about doing a restore and losing my stuff, then held these two buttons down for about 45 secs, the Apple logo came up, and about 2 minutes later it booted up.

Thanks so much Kaitlyn, I can't thank you enough. Best wishes.

OMG! You are a life saver! Totally worked! I was sooo upset. Thought I was going to the Apple store! You're the best! Thank you so much!!!!

Totally worked! Thank you so very much🙂

Thank you kaitlyntre

I can't honestly thank you enough...I was panicking about to go to the store to buy a new phone...seriously panicked...lifesaver thank you so much.

Nothing is happening, I tried holding the buttons down for the 45 seconds, nothing happened. It's been charging for an hour now, but was 80% charged before it died. My contract ended in November 2013 and I had downloaded the new update (7), thats when it started having problems, Any suggestions would help.

OMG I'm having the exact same problem except my on/off button on top has been broken for awhile so i cant hold it down or anything like that to fix it & I'm scared to take it apart and screw something up. :/ Please HELPPPPP

Does this work with an iPhone 4S? Please help! I've tried a hard reset and it won't work. Does this also save the data? I have a bunch of music and pictures on my phone. It's only 1 year old. I don't know what to do!!! D: :( :O

Hey! I have the exact same problem. How did you fix it? Please let me know

So weird my phone would ring, Siri would go on, vibrate, etc but screen was black and I couldn't turn the phone off, or on. I held the power and home button down at the same time for several seconds and voila! the Apple symbol turned on. I touched the screen, pressed the home button and everything was back to normal. Whew.
