replaced LCD and now the phone stays black.
I broke my LCD (not the touch screen but only the actual lcd). I bought another one and replaced it following the instructions that are found all over the internet. Easy to do. For the first day or so the screen looked OK except that sometimes it would just be white noise and I would have to squeeze the top of the phone for the correct clear screen to appear. I thought that probably one of the cables wasn't connected correctly. Ribbon number one doesn't seem to connect very well and always seems to be loose. I made 100% sure that it was connected correctly and put the phone back together. Now the screen is completly black. There is no light what so ever. I have done a restart by holding the power and home buttons. It still rings but I can't answer by sliding a finger across the bottom of the screen. It doesn't make any diference. Itunes recorgnises the phone OK though and it also vibrates when I flick the silent switch on the side. I have also put the original broken lcd screen back in but this one also doesn't display anything at all anymore.
Is there anything I can do to test this or repair it?
Is this a good question?
