Replaced LCD. Screen is black. Able to answer calls and have sound.

I just replaced the LCD on my iphone 4. I cannot see the screen. I do hear sound when receiving messages or even answer calls. I was able to answer a call from my other phone sliding the finger where it should be done. I have rebooted the phone and still nothing. Even though I do not see anything, it kind of works because i was able to answer the call. What's wrong with my phone? Is the LCD messed up? is it some wiring?

If you were already having this issue then the fix below will not work.

Check the flex cable and clean the contacts with 99% alcohol and a toothbrush (both the logic board and flex contacts). Make sure that the alcohol is at least 92% if you dont have 99%. No need to use much a little will do. Wait a couple of minutes till it dries a put it back together. It should be good. If the screen still is black then your screen needs to be returned.

I have not clean anything inside the phone. Do you think that should make a difference?

You do have to start the process of elimination. cleaning the contacts is a common fix for a new screen fix.

I reconnected my broken screen and it still works and I can see everything on the screen. I put the other two digitizers I have received, and on both of them I cannot see anything. It seems that the digitizer is not working. I need to return the items back.
