IPhone Screen shows no image whatsoever?

All of the sudden my iPhone 4S broke down. I can hear texts coming in and Siri is able to beep in (but do nothing) yet my phone shows no image or light of any sort. This happened out of nowhere (phone wasn't dropped or broken) and sadly in the middle of a very important texting conversation. Any help solving this issue would be appreciated. I've also tried resetting it and although it is evident that a reset is possible (deactivates any noise) it starts back up with no white apple sign and clearly isn't fixed

Hi
Seems your problem is fixable. I suggest you should go to the dealer or any apple store and ask them to fix your poblem. Sometimes we feel that we can fix it but when we're not sure then it's better to go to a professional and ask him/her to fix the problem.
