    • Areas highlighted in red show three solder joints to the right of the battery, along with four smaller solder joints located to the left of the battery.

    • These joints secure the power/volume flex cable (leftmost joint) and the battery flex cable (rightmost joint) to the logic board.

    • In the next few steps you will desolder the battery and power/volume flex cables from the logic board.

    • These joints may be coated in a clear silicone/glue, which must be removed before desoldering.

  11. iPod Touch 4th Generation 30 Pin Dock Connector Replacement: Schritt 11, Bild 1 von 2 iPod Touch 4th Generation 30 Pin Dock Connector Replacement: Schritt 11, Bild 2 von 2
    • Using the heat gun, heat the silicon/glue for 5-10 seconds, then use isopropyl alcohol and a q-tip to remove the silicon/glue.

    • DO NOT overheat the silicon/glue as it will turn into a liquid and ooze everywhere.

    • The two ribbon cables are attached to the logic board via solder pads with small holes that go through the cables and attach to flat pads on the face of the logic board.

    • To desolder the battery flex cable, place a copper desoldering braid on top of the existing solder pads and press down on the braid with the soldering iron.

    • Once the solder melts and flows into the braid, remove the braid from the pad.

    • Process may need to be repeated two or three times to ensure complete removal of all solder.

    • Beware of overheating the board and the cable. Only hold the tip of the iron against the pad long enough to let the solder melt. Excess heat buildup has the potential to ruin the logic board or melt the ribbon cable.

    • DO NOT bridge the connection between the solder pads both on the board and on the ribbon cable. Shorts have the potential to ruin the logic board.

    • Repeat this process for the power/volume flex cable.

  13. iPod Touch 4th Generation 30 Pin Dock Connector Replacement: Schritt 13, Bild 1 von 1
    • Once all solder pads have been removed, gently pull both ribbon cables from the logic board and bend them back to keep them out of your way.

    • Desolder the two solder joints and the 30 pins.

    • To desolder the solder joint, place a copper desoldering braid on top of the existing solder and press down on the braid with the soldering iron.

    • Once the solder melts and flows into the braid, remove the braid from the pad.

    • Process may need to be repeated two or three times to ensure complete removal of all solder.

    • DO NOT get solder on the highlighted gold ring, as you will not be able to remove it.

    • Repeat this same process for the other solder joint and all 30 pins.

  19. iPod Touch 4th Generation 30 Pin Dock Connector Replacement: Schritt 19, Bild 1 von 2 iPod Touch 4th Generation 30 Pin Dock Connector Replacement: Schritt 19, Bild 2 von 2
    • Once all solder is removed, pry the dock connector straight down from the logic board using a metal spudger.

    • DO NOT remove the dock connector before all solder is removed, as the pins will rip from the dock connector and get stuck in the logic board.

    • If done properly, you should be able to see straight through the logic board where all 30 pins and the two metal joints used to be.

How do I reconnect the "display data cable"?

snowshoe2009 - Antwort

If I read the instructions correctly, the "display data cable" is very short and the multi-contact connector from the iTouch screen meshes with a like connector inside the iTouch. That mesh does not appear to be very secure. Are the two connectors supposed to lock or just touch? I can't tell if contact is secure and I get no display on the screen. The battery has been replaced and, I assume, charged, but I have no way to check the voltage without disassembling the unit, once again. Aside from this problem, the top of the case (screen) doesn't lock into the bottom half. Could some sealant be preventing the locking ?

Hello,

There is as small resistor underneath the red cable of the speaker. It certainly broke up when I changed the 30 pin connector and I lost it.

Do you know its value so I can solder a new one ?
