Rispondi a "Water damaged phone, turns on but screen is black"Hi David, before continuing reading this: Remove the battery as soon as possible and DO NOT CHARGE! If a device is exhibiting symptoms of water damage the first step should be opening the device up to just double check that there isn't water still in it, shorting something out. (I have opened a phone up that got wet and was dried months ago, and still had water in it on the motherboard.) 1) Open it up, if water is there disconnect all power sources (including battery if possible), 2) next remove the water, (see footnote 1) this can be accomplished by drying with a hair dryer (not on high), 3: next put in a bag with some dessicants (see footnote 2) for 2-7 days, reassemble and voila! Footnote 1: an optional but highly recommended step here is to pour 97% isopropyl alcohol in the device (but try not to pour on a screen, it can mess with adhesives) the benefit of this is the alcohol will often displace the water, meaning you now have a device that is now soaked in alcohol, still not ideal but way better...
Rispondi a "Touch ID inconsistent after screen repair"Hi Andrzej, I am not sure if this will entirely solve your problem but it should at least answer a few of your questions. The metal panel that you removed serves as a heat barrier between the screen and the internal components of the iPhone as the backlight can generate a fairly large amount of heat. It also serves as an electromagnetic barrier to prevent the high voltages used for the backlight/screen from adversely affecting the phones internal components. I would suggest you reinstall it but thats up to you. As for why Touch ID isn't working, there are a few potential causes. It could be that the metal barrier not being there is causing interference with the cable, so I would first try reinstalling that. Then check the contacts of the cable, and make sure the connection points are clean (95% isopropyl alcohol and a q tip with some type to dry are great cleaners). It could also be that you tore/kinked the cable when reinstalling: in which case replacing the cable should fix the problem. If you have a...
Rispondi a "Beginners tips /help please"Hi John, As a primarily self/internet taught electronics repair person, here would be how I would approach this. Assuming you are a beginner to this and don't have a lot of tech toys to troubleshoot this we will only use a multimeter (available for $5-$70 depending on how many bells and whistles you want, this one for $6.40 on amazonshould work perfectly fine). for a description on why you want a multimeter/why it is useful, see footnote 1. I will also assume that we don't have a schematic of the device in question because lets face it, most of the time you don't. Lets take your scenario, in which a customer (friend) tells you their device (a smartphone for example) doesn't turn on. first try to ask them what they think happened. If this is a device that doesn't turn on randomly, or if it was acting odd (i.e. erratic performance, not attributable to a single point of failure) before it stopped working, then odds are it is water damage, (to treat this look at footnote 2.) If it doesnt sound like water...
Rispondi a "Can the hold button be replaced if broke?"you could always buy a broken ipod (maybe a water damaged one) off of ebay or some place like that and use its hold switch from that. however it would require some fine soldering.
