LCD Display, could be broken Logic Board

Directly in front of the LCD Display pressure clip on the Logic Board there is that small brass clip. The little finger part of the board itself looks damaged...would this restrict the phone from displaying anything to the LCD? What does this area control?? I will attach a few picture to help understand what im talking about. The 2nd picture shows the headphone jack and volume control is also ripped.

Thanks in advance,

This 'finger' you are talking about is connecting to the metal ring of the iphone for the antenna function. It has nothing to do with no LCD function and also looks pretty normal to me.

Have you already tried a new LCD to see if it helps? If so what do you get on the screen. Is it no image or lines and is the backlight going on?

Possible solutions for no LCD:

1) When installing, you need to be very careful that the LCD cables are fully pulled through the opening in the frame. Pinching them even the slightest can wreck the cables and result in a non functioning LCD. Recheck that these cables are all the way through.

2) If so, insure the cable are properly seated on the board. Make sure the Back camera's tail is UNDER the two LCD cables.

Hope this helps,

Thanks for your quick responses,

Gido; the third picture...there's 2 fingers that are supposed to be the same dont see that one is chipped like a tooth??

This is my bro's phone, he said he tried doing before me and was unsuccessful. I'm wondering if he maybe didn't pull those cables fully through and put a crease in the cable, would that cause a complete black screen or discoloration??

Sooooo....this is another problem....i have one of your trays for sorting...well my dog was curious today....and knocked it over...i had 2 iphone4 set's of screws in it.....trying to distinguish between the .1 mm differences, thread thicknesses is merely impossible!! is there a guide to help separate these properly, or even a screw package that has them separated and labeled for you??? Say..the 1.4 mm would have 4 threads from the throat to tip...something along those lines?

On the logic board itself...where the wifi antenna brackets is fastened. The 1.6mm screw closet to camera...are those little circular nuts that screws anchor into supposed to be fixed to the board?? will soldering be needed??

Greatly appreciate all the feedback,
