  • Answer to: Repair power (on/off) switch?

    Success!! I completely took it apart again. Removed the display assembly (but not separating this), mother board and sync connector. Cleaning everything by blowing clean, compressed air (from a aerosol can) in every nook and cranny and trying to get air in between the mother board and the RF sheilding from all directions, blowing everywhere on the back case and on and around the buttons (that where still in the case) and on all connectors (both on the mother board and on the flex cables). Then assembled everything again, making 100% sure that all the connectors where correctly seated. Turn it back on and loo and behold! Everything works like a charm!! I can turn it on and off, I can enter DFU mode and it doesn't reboot as soon as I unplug the sync cable!! Dang, I'm a happy camper now!! :D PS. Just in case this haden't worked, my next attemt would have been to spray/use some 'electronic cleaning solvent'.

  • Answer to: What do I need to do to get the power button working?

    I'm quite sure that I put my replacement harness in correctly, but I can't get it to work either. The phone is constantly on and I can't get it to sleep by just tapping the sleep/power button... I've tried complete reformat and restore, downgrading the OS etc but still no go... I'm as lost as you. I can't think of anything else other than the motherboard that can be wrong, but I'm unsure what. A new motherboard is >$100 so that's not an option...

  • Answer to: On/Off Button doesn't work! iPhone permanently on.

    I've now replaced both the battery and the button harness I mentioned, but still no go. I can't turn the darn thing off (!!) and I have no idea what can do this other than the button itself!! I'll try Marks idea as soon as I'm sure that the battery is fully charged.
  • Answer to: Audio Head Phone Flex Switch Cable?

    Try replacing it. Search for: Apple iPhone 3G Head phone Audio Jack Flex Cable Black on eBay and you'll get quite a number of hits. The price is from $3!
  • Answer to: Messed up where number 3 on the logic board goes any ideas?

    I got the same problem. To many open/close I guess :). Luckily, my younger brother is a real star with surface mounted components. But tracking down a new one was a lot harder! Finaly I found a site: http://www.earth2k.com/fpc-ribbon/ Doesn't cost a fortune, but a little on the expensive, especially with S&H to Sweden! But it still beats a brand new iPhone :). Before I realized that my brother could do this, I did a search on the 'Net to see how difficult it was. Nothing for the faint-of-heart! It's not impossible, but way to ... risky for me. So instead I looked at some forums (there where quite a lot of them!) and found some people that said the could do this. So I thought about mailing a few of them and ask if they could do it for me... Luckily I didn't have to, but this is an idea for the rest of you...
  • Answer to: Dropped in water. Dried out and charged. Now turns on and off.

    I have almost the same problem (although I need to force the 'usb poiting to iTunes' screen by going into rescue mode. I'm 99% sure that my problem is a bad battery AND a bad/broken power (on/off) switch. I'm going to try cleaning it or if that don't work, replace it. See other posts for more info...
  • Answer to: Phone freezes / shuts off when not plugged in

    I've seen other answers that indicate that this is a battery problem.
  • Answer to: On/Off Button doesn't work! iPhone permanently on.

    I have the same problem. I took my switch apart and will try to clean it (mine was dropped in water by previous owner). If that don't work, a new cable harness (including the switch) costs £4.99 on eBay UK (seller phaetondvip88 - I've bougth from them before and are very satisfied). The harness is labeled as 'Apple iPhone 3G Head phone Audio Jack Flex Cable' in their shop... But, I'm going to try clean it first... Just need to go out and buy some 'electrical cleaning solvent' or whatever it can be named :)

    And my younger brother managed to replace it with only a couple of minutes whining about it's size :).

    Works just fine now (exept that I can't seem to turn the darn thing off, even though I've also replaced the button harness!)

    Quote from Vishal Vaidya:

    Is there a way of replacing the connector?

    You could replace it. That's what I'll have to do. Luckily my brother is great with soldering surface mounted components.

    But if you had to ask if it can be replaced, you don't have knowledge to do it yourself! It's VERY difficult! Look among your friends or the 'Net. I found quite a lot of forums where they talk about the difficulty on replacing SMD's. Just mail one of them that seem to know what they're doin'...
