hi Anonymous. You might want to try a hard reset. There are anecdotes on this thread
How to fix black and unresponsive iPhone screen 5S describing the same things, including Siri being clueless. screen suddenly blank.

Hoping this will help you as well!

Hi Anonymous,

if sliding your finger across the "slide to unlock" bar won't unlock your iPhone it's possible that your touch screen is (partially) broken.
Try a reboot first: Hold the Power-Button until the "Power off" slider appears. Hopefully you can slide that. If not hold Power and Home-Button for approx. 10 seconds until the phone is off.

If after starting your phone again you can't "slide to unlock" you should see to get a screen replacement.

Try holding the power and home button, restarting your phone. Continue holding until Apple logo appears and then let go of power, continuing to hold home.

probably the touchscreen just broke on the bottom part after a while

Check the 2 pins connected on the home button if touch the interface of the board,might not hitting that is why the slide unlock not working.

iPhone setting:*
- Auto-Lock: 1 Minute;*
- Passcode Lock: On, require passcode immediately, after 15 min or 4 hours etc;*
- Network: Turn 3G Off

Scenario 1: Home screen is active with screen on*
1. Press power button for seconds until asked to '"slide to power off"
2. Slide to power off
3. press power button to turn on iPhone
4.*When asked to enter passcode, touch the "Cancel" key, then slide to unlock
5. bypassed passcode

Scenario 2:*
1. On the screen of being asked to enter passcode, press power button for seconds until asked to '"slide to power off"
2.*Slide to power off
3. press power button to turn on iPhone
4.*When asked to enter passcode, DO NOT touch any key on the screen, press power button for seconds until asked to '"slide to power off"
5. Slide to power off
6. press power button to turn on iPhone
7.*When asked to enter passcode, touch the "Cancel" key on the right bottom corner, then slide to unlock
8. bypassed passcode

Notes:
1. When Network setting changes to Enable 3G: ON, "3G" signal shows up, passcode CANNOT be passed through
Go to a underground parking lot or a lift where 3G signal is weak, when 3G signal switches to "E" (Edge), passcode CAN be passed through following above steps
2. When no 3G or Edge signal, above steps don't work

Conclusion:
Seems passcode security is related to network status
Possible security hole under Edge

my cell iphone 's screen is not working. it became black with an arrowhead.

try hard reset (hold down the power button and the central button until you see Apple logo on screen). If this wont help then use RESTORE.

I have the same exact problem. I dropped mine, and it landed half on concrete, half on a piece of foam board, and when I got to shut mine off, it will slide to power off, but will not slide to do anything else. Everything works perfectly fine, people calling me, texting me, nothing is broken or cracked, I can't even unlock mine, it's stuck and it's making me very upset! I want an answer as to what I can do and or can't do.

The most likely reason is that the touch pannel you have installed is defective. One of the printed connectors on the connection tape is not working correctly.
Try installing the old screen again and see the results (if available).
