Screen is not turning on despite replacing the LCD, Main flex cable

Hi there, This is my first time here at this forum but I really need help and I'm hoping somebody in this world will help me get my phone out of its coma :)

So the last September I got myself this used Z3 dual ( d6633 ) from a guy I know, The phone was in a descent condition, only changed the back cover and main flex cable as his previous owner stated at the time (which turned out to be a lie) , but after 3 days of using I noticed that the screen is a little bit out of the frame and I decided to open it up and put the double face adhesive in a different way under the screen in order to make it well glued to the phone. Of course when I opened it up I found that the last person who fixed this phone had actually put adhesive under the middle of the screen not only on the frame which upon trying to get the screen out it completely was torn apart and I had to get a new one.

So I bought a new screen, new main flex cable and an antenna plate cover . I noticed that there was no antenna plate cover in the phone and it was working fine but I thought I should buy it anyways.'''bold text'''

Now I connected the new flex cable and attached the antenna plate to the little board down there in under the battery and connected the new LCD, but no hope!

when I booted up I heard the opening sounds but the screen wasn't working. Also I can use the camera button to take pictures (knowing from the sounds) but the screen is not turning on!

Also worth mentioning that

1. There is a little wire coming out under the Main board (See pics) That I don't know if it is important or not but I assume that it had a thing to do with the down board or something, I don't know!

2. When I watched assembly videos of my phone on youtube I noticed that there is a thin metallic plate that is put under the small board (see pics) this plate I don't have in my phone!

3. As I mentioned the phone was working without either the thin plate under the small board or the antenna cover over it ( That's why I think that the thin wire coming out of the main board actually had a role to replace them)

Please if you had a similar situation tell me what could possibly be the reason why the screen is not turning on! and Is that wire really was intended to do something or not? If I buy another screen will that work or is it something else that is making the screen not go on?

What I'm getting out of this, is that your phone works, but your new display assembly doesn't. Likely you purchased poor quality parts, and that's why you're having this issue. It could be the connector on the logic board, but that's a whole different problem to rule out. What I didn't see in your post, is if the original display assembly you had, was working or not. This would help to rule out if your new display assembly is in working order. Or hopefully should

If it's the connector on the logic board, what can I do?


Hey @iMedic .. Please Help me!


Ok, ok. Did you check your original display? To see if it works? So you can rule out the new display as being faulty?


If it's a connector on the logic board, you could try and replace it yourself. It is do able. However micro soldering isn't for the feint of heart. Fortunately Jessa Jones at iPad Rehab is very good. She has a mail in service, and pretty much knows everything


The original display is completely torn apart so I'm pretty sure it's not working..

Meanwhile I opened up my main board and actually found that there is a soldered on it... I don't exactly know what is this but I'm assuming that it's something like you said... What do you think about that? Where is this wire should be connected/soldered on its other end?
