i have the same problem.
1. plug it in with power chord
2. Apple logo pops up for 1 or 2 minutes
3. i start holding down button combinations, and the apple goes away, screen seems like it goes black. but at night you can see the display is fully lit.
4. holding "home and sleep" to get the red slider gets me a horizontal one pixel blue line, a quarter of the way down from the top of the screen.
if i plug in to MacBook pro...
5. same as step two above but
6. image capture launches and photo thumbnails appear from my camera roll, while apple logo remains on screen.
7. at that point i have about 30 seconds to copy photos to my desktop, then the phone restarts and image capture loses connection.
8. steps 6 and 7 repeat endlessly.
i have replaced the dock connector once, with another known functioning iPhone (we have two in the family).
i have also swapped batteries, but i'm having the same behavior...
i have a "new" dock connector coming in the mail, so i'll try that next.
in the meantime i'll swap logic boards to see if that is the issue.
unfortunately i've been out of hard disc space on MacBook pro so i have been unable to backup my iPhone. so it will be painful to RESTORE the phone.
[i have also swapped Headphone Jack Ribbon, and Power Sensor ribbon and removed a broken front screen from the phone i'm robbing parts from. i am using a highly organized system of ziplock bags to keep it all straight, so i don't think there were any errors.]

Hello Omar. Have to ask some questions here. Has this phone suffered any water damage or falls of any kind? When did it start exhibiting this behavior? What iOS version are you running? Are you syncing with Mac or PC? What version of iTunes are you running? You have obviously tried relevant hardware fixes, so lets look elsewhere before ruling on a bad logic board on the phone.

Hello,
To my knowledge the Phone hasn't suffer any water damage. It actually started developing the fault like 2 Weeks ago, I left the iPhone on change throughout the night, when i woke up I realized the iPhone's battery was completely flat, therefore wasn't charging at which point I tried using alternative USB cable on both PC & Brothers Macbook (Still not charging or syncing), as well as wall plug. Itunes version is latest version, IPhone is still IOS 6.1.4

If you are positive you replaced the dock connector with a KNOWN GOOD ONE, then the obvious next step would be a restore of the phone to ensure there isn't a rogue process or plist file causing this. Being that you are on 6.1.4, I know that you are trying to preserve a jailbreak maybe?!? If not, try restoring your phone as new to the latest firmware for your phone. If the dock connector you installed is a good one and a restore doesn't help, then you might be looking at a logic board issue.
