My iphone will not turn on and it has a broken lcd but it was turning on last week but i tried to fix th power button and now it wont work

Hold the power button and home button down together for 10 seconds, or until you see a white apple.

its a hardware problem from your power button and causing some shortages so your phone wont open up. if you know how to disassemble your iphone you can probably fix it but be careful if your going to disassemble it make sure you dont loose some parts and tear the flex cables :)

Did you tried press the power button while holding the Home Button pressied ?

I have seen this happen wit a few other Iphones and the hardware parts for the power button seem to be very fragile and easily broken.

Hello ! I was in panic attack !!! did everthing and nothing seems to wake up my iphone. I forgot to charge it so battery went full empty, then I plug it on the wall charger, and nothing happend. I let it all nite, and next morning,... surprise !!!!! still the red icon, No battery, the iphone didnt restart!!!! How I fix it?
1-unplug it from the wall charger 2- press middle button and startup button, same time 3-when red battery dissapear, plug the charger. 4_ do this many times. Didnt work for me the first time, but at the end it works !!!!
NOW MY IPHONE IS WORKING GREAT !!!!! GOD BLESS YOU ALL !!!!!!!!

Keep the home and power button pressed for 10 seconds, then, leave power and keep the home button pressed...shud be able to see the charging cable logo...then restore it...

hi...i already written something about that therefore i have just copy and paste it... --> If you have some problems with your iphone like it wont turn on or it wont react even though you tried things like hold both buttons simultaneous or some other stuff and it dont helps....then there is the last possibility before you have to go to an apple store....and hope that they fix or replace it! you have to bring your phone to the DFU modus...for it follow the next steps: start itunes and plug-in your iphone even if it is turn off or it just shows the apple logo.... further press down the power button for about 3 second, then press the home button WITHOUT release the power button and hold both simultaneous at least 15 second.... finally release the power button and continue hold the home button for about 30 seconds... now the iphone should be detected by itunes. it ought to recommend to restore it to the factory defaults! after that you iphone should works correct again... hope my instructions are useful and let me know if it works on ur iphones!

If it is a blank white screen then your lcd is broken. you would need it to be replaced. to be sure its broken. let the iphone power up and after 5minutes plug it into itunes. if it connects normally then this confirms that the iphone lcd is broken. if not try to do a restore.

ROUND BUTTN U MEAN THE HOME BUTTN? JUST HOLD TOP BUTN AND HOME BUTN FOR 6 SEC AND SWITCH OFF THEN TURN ON AFTER 3 MIN
