LCD connector and digitizer cable - troublesome. Tips?
I'm repairing an iPod Touch [Gen 4] for the first time. Two to be in fact.
The first one, I pried apart because the home button previously was not working.
1) The sleep button no longer works when the case is off - or at least this perhaps might be the case. I can't really be sure, but it makes no noise when I press it.. but the case was dropped and the button hardly moves so it perhaps possible it was jammed. Is this possible to do when the case is off or does it connect to a button on the logic board? I've read it shares a flex cable with the volume.
2) The LCD Connector came off so I cannot even test the home button OR the sleep button. Worst of all, I turned the iPod on when I THOUGHT I had it in.. but it just fell out. Now the device is just running. [Plugged cord in and heard it make the 'connected beep'] Why are these so hard to get back in place? The LCD specifically for this one.
3) The 2nd one has a spotty touchscreen and shattered glass. The steps are fairly similar to for disassembly on it.. but I'm afraid to mess up the connectors and I've heard horror stories of sleep buttons stop working and other sorts for no reason. Tips to avoid such trauma?
Thanks a lot!
Be VERY VERY careful when removing the metal plate after you remove the glass/lcd. the loud speaker is taped/glued to the bottom of the metal plate near the home button on the left side. I recommend using a heat gun for about 5 seconds on that corner to loosen the adhesive before removing the plate. Also, be VERY VERY careful when you pull the plate up. You can see next to the volume buttons as you gently hold the plate up just a bit, the flex cable that controls the volume and power buttons. You will need to gently loosen the adhesive that is holding the metal plate down while also using a pry tool to hold down the cable/logic board, under the plate, where the cable connects to the logic board. If you are not careful about these 2 things you will either tear a speaker wire from the logic board or you will tear the flex cable for the volume/power button.
