I would recommend a screen removal and a thin pointed needle nose pliers. Try and get just the rim of the metal backing where the bend/dent is located and pry the screen back so the button can retract and work again. I would order a back replacement ASAP and find out which replacement cables are needed and wait for a good collection of instructions and do some soldering.
No. If you want it factory flush. You will need to remove the adhesive from the sides, metal plate next to the home button, top and bottom of the ipod. Then apply a very small amount to the upper left hand side and just a little dab on the black plastic on the bottom. You need remove all the adhesive to get a great fit.
Try Holding the power button on the back until it turns off Then press it again to turn it on while holding "ALT/Option" key. Your hard drive should appear as mac osx or something similar. Highlight it and hit "enter/return". This will reload the kernal and close out running programs on your OS that may have prevented it from turning on. If this doesnt resolve you may have a blown capacitor in the power supply unit PSU. Google "on board diagnostics for imac intel 2006 or g5 depending on what you have" and test the Power Supply Unit with the led lights on the mother board. IF this doesn't work and you ended up taking apart your PSU and visually checking for blow capacitors then you will need to look up how to replace your GPU, which is not only difficult but usually requires the same model motherboard just for the part and Will require soldering
I used a $3 soldering iron from O'reilly auto and successfuly did this by leaving it plugged in for 5 minutes and used capper solder wick to remove the old solder and taped it in place with a piece of scotch tape. after I sprayed it with flux and put a little dab of solder on each point waiting 20 seconds btween solders. I did it though. No blobs crossed voer and crossbridged and the reassembly was a success. If anyone is changing the back out on a touch 4, you will need to do this nomatter what. There is absolutely no way to peel the strip without breaking it. I use super glue to glue it and it works great
Next to wifi cip under the dock connector there is a little blue capacitor thats is commonly knocked off. You can cut a cord and extract a piece wire from it and lay it over the two points where the contacts broke off and drop a drop of flux on it, then touch it with a hot iron with a little bit of solder on it and it should be back to or better than its old self. If thats not the issue however, I would clean your contacts with a toothbrush and windex and reassemble
Its pretty easy. Update in itunes and re-jailbreak and unlock. If that doesnt fix it, just buy a replacement battery from the fine folks at ifixit or ebay because they seem to quite a bit cheaper there
I refer to the ifixit "2nd Gen Ipod Touch Battery Replacement" and skip to the soldering section for clear instructions on how to solder the volume cable. Its careful soldering and dont forget your "flux". Im doing exactly what your doing right now as I type this.
I would uninstall the logic board and if it had water damage I would reclean the connections to all zifs and cable connectors with windex and a toothbrush and try reconnecting it. If it didnt have water damge I would clean them anyways and make sure their tightly seated
Well it 15 seconds, but I doubt thats the issue. I would try connecting it to itunes first. If it doesnt recognise it turned off or not, you will not be able to turn it on with a button combo. If you know this had water damage then I would diagnose in the order: a new battery > Dock Connector> Logic board cleaning> Logic Board
This happens to my satellite too. Heres what I do to fix it. 1.Take Battery out 2.plug power in 3.while battery is still un-plugged and turned on pick up your laptop and tip it all the way sideways quickly. You should hear your fans boost and your screen will turn on. 4. replace battery while still turned on.
