In addition to the steps in my original post:

"The exact sequence was:

•    The battery ran out

•    I connected the phone to my computer via USB (no reaction on either side)

•    Held down power/home to enter DFU

•    Apple logo appeared on the iPhone

•    2 minutes later the phone was up and running"

the only thing that comes to mind is powering off the phone. Did you let the battery drain out completely?

I set up an autodialer that called the number repeatedly, until the phone dropped off the network. I only did that because I knew it had a full charge, and I was in a hurry to get it working. You could just wait it out.

I am having the same issue. Until now I never any issue with my phone, have had it since the day Siri was released, purchased at AT&T store. Suddenly the screen went black, seemed completely unresponsive and got very warm. (No yellow triangle warning symbol however). Tried hard restart several times (sleep/wake button + home button) Very strange thing also happened to me which no one else has mentioned: the camera flash would illuminate at random times, then turn off. I did a complete restore connected to computer through itunes, which took 2 hours. Phone is functioning, Siri follows commands (Call a specific person etc) but screen is not illuminated.  I can end a call because I know where the "end" button is on the screen. I cannot see any of the apps or cannot use any of the functions of the phone requiring touch screen due to black screen.

hello ihave iphone 4 black secreen phone not work when update the phone itunes show 1601 errer what can i do help plzzzzzzzz

i solved mine , with no particular way . I just left it there for awhile and then it turned on again and worked .i guess these are minor problems , the same way where our PCs might just hang/crash for no apparrent reason. Another thing is i had run into problems updating my os on my Pc. i used my sister's macbook and it didnt have as much problems.(i'm talking about when trying to update the iphone OS , sometimes itunes says that there's an error and can't upgrade.)

I just experiecnced this right now. I just plugged it in to my computer and restored it and now its working fine.

Same problem. Phone got drained. Charged at home. After a few minutes, screen lit up as usual then it started to fade until it was totally black. Allowed it charge more. Same as the experience of others, I knew there was power and the phone was working - could receive calls, could tap in numbers to unlock the screen - but nothing is displayed. Am presently restoring and waiting for full charge. Will see what happens.

Restore didn't work for me. Still with the blank screen.

After resetting and restoring nothing happened. So left the phone as you did. The next morning, the display turned on and the phone seemed to be fine. But then the screen started to fade again and I'm back to the blank display.

Hi I live in Vancouver BC Canada. I bought my new iPhone 4S from Metrotown mall 1 week ago. I have had the black screen 2 times now. I didn't see it fade it was instant black.  Phone still powered on. I have been out of town for the last week or I would have returned the phone already.

I was able to get the phone working both times in 30 seconds. I pressed every bottom on phone hoping for some magic and It came back to life. It happened first 36 hrs after purchase and again 5 days later (now).

my wifes Iphone 4 is having the same exact problems...i was thinking t wsa a hardware issue but the funny thing is when i hard reset it i get the apple logo its a lil distorted but its there. Ive tried everything possible i think that we are just going to have to make a 1 hour trip to the apple store this weekend

Hi I posted on this thread 5-6 days ago. The phone has had the black screen 3 more times in 5-6 days. What I do to fix it is swipe the phone to unlock it... Because even though phone looks dead it's still alive and you'll hear phone unlock. Then I press and hold down the home button for few seconds until you hear the beep that allows you to give phone a voice command. Then I press the power button on top of phone and it works again. 

I do not know why this is happening, I'm pretty sure I was doing different things each time it went black, but reality is every time it went black while I was using it.

Will update soon.  I will be back in Vancouver in 2 more weeks and I'll return the phone for new one.

As mentioned here before, my girlfriends iPhone 4 had/has the same problem.

We brought it in twice and it was send to an authorized repair centre twice(!)

- first time it wasn't repaired at all (no failures found)???

- second time they 'replaced parts' (not specified)

I wonder what exactly?

Altough it seems to be functioning better now, the phone still has erratic blackscreens once in a while. Our other iPhone 4 never showed this behavior. Bit lost here on the question if we should bring it back for a third time.

Any (ex)Genius here who actually knows what's wrong?

Thx,

Arjan

Had already sent in the phone for repair. They told me it usually takes more than a month. Was not able to try your suggestion. Wonder if it would have worked for me.
