    Hey guys, this is my first post.
    I registered to this forum in order to have some help from Youi :D

    So, I bought some iPhone 3GS in stock on eBay.

    Two iPhones have the same problems:
    -display NOT working (nothing appears on Display but the digitizer seems to be OK)
    -when I attach them to the PC, it doesn't recognize them (anything happens, even if I attach them for 2/3 hours).

    So what could be the problem? How can I test their motherboards without a display (if the motherboards are "dead" I won't buy a new display).

    Thanks in advance :)

    UPDATE.
    I searhed on Google about the problem and I found a solution:
    -attach the iPhone to the wall charger for about 2 hours (in order to charge a bit the battery)
    -then move up/down the iPhone's mute button (the button on the left) and keep holding home and power button
    -after all this, I connected to my PC and it recognized my iPhone:eek:.

    BUT, it seems that the battery doesn't charge with the cable attached to the PC AND in 2 hours it recharged ONLY 22%.

    Is it the battery in the end of its life :confused:

    UPDATE 2.
    I left the first iPhone connected to the PC but it seems that the battery rest at 22%:eek:

    I tried to turn on the second iPhone with the same way BUT my PC don't recognize it.

    When I connect the iPhone to my PC, it says "USB Device not recognized".

    So, what could be the problem with these two iPhones?

    Can someone help me? Thanks in advance:).
