Hi
Have an ipad 2, repaired the front digitizer but every time I put the front half of the screen down it loses all reception, it works fine when the top half of the screen is not down...
I presume something is shorting out or the antenna is not correctly connecting to the case or something?

I'm going off memory here, so please forgive me if I'm not spot on.
There should be 2 connections on the bottom of the daughter board for your cellular signal. When your screen is put on, its pressing down on those connections. The first thing to check is those connections, making sure they are seated properly. If they are seated properly, then there is a chance that you tore one of your antennas when you pulled off the old screen. It happens, I've done it too many times. Check those antennas (you have to do some work to get them out) and see if you can find any tears. That is a very cheap fix.
There is a chance that the daughter board could be bad. There are plenty of used ones out there for dirt cheap. I've personally never seen this be the case, but it is possible. I would focus on the two connections and the antennas. Those are the simplest and easiest fixes and also the most likely.
这个答案有帮助吗？
Thanks, I have ordered the two antennas.
It's strange because it is fine with the bottom half of the screen seated it's only when the top half gets pushed down
In my experience, its pretty common for issues to show up once the screen is on but not appear with it off. At least this one sounds pretty cut and dry. There isn't a whole lot that could be wrong here.

Is this for cellular (3G / 4G) or Wi-Fi reception?
Wi-Fi reception is the bottom antenna probably at fault.
The cellular reception are the two top antennas, one on the left side at the top and one at the right side at the top. Front camera is between both of them.
Are they cut or damaged in any way? Tearing of the antennas can cause this issue.
