Hi everyone This is technically NOT a repair question, and I apologise in advance if I'm breaking site policy here... I'm...

Hi guys! I'm a repair guy, been fixing smartphones for around about 2 years. Have seen quite some weird stuff happening,...

I've seen this behavior in an iPhone 6S before, it turned out the rear facing camera was internally damaged, causing all the camera's to stop working. I suggest you open up the phone and disconnect both camera's, see if the flashlight comes back to life. Then you can plug in the camera's one at a time and see if one of them works to isolate the faulty camera. The teardown guide can help you open up the device. Good luck! Smontaggio iPhone 7

Doesn't look good for this model, according to the manual on page 46 (https://www.lenovo.com/shop/americas/con...): "If you forget your administrator password, a Lenovo authorized servicer cannot reset your password. You must take your computer to a Lenovo authorized servicer or a marketing representative to have the system board replaced. Proof of purchase is required, and a fee will be charged for parts and service." You can try to disassemble the laptop and remove the small cell battery on the motherboard, but not all laptops have password reset options anymore these days.

A screen is composed out of different components. On the inside you have the LCD which displays the actual images, in the middle you have the 'digitizer' which responds when you touch the screen, on top you have the protective glass. When discoloration or vertical / horizontal lines occur, the LCD is most likely cracked or damaged by the fall; even though no cracks might be visible. You should try to replace your screen, it's fairly easy and iFixit has a guide: Sostituzione LCD e digitalizzatore iPhone 5s

Do you have gray bars appearing at the top of the screen? If so, your phone suffers from 'touch disease': https://www.youtube.com/watch?v=RPWCiQ65... In that case, replacing the FPC connector won't work, you'll need to replace the touch controllers. A complete walkthrough for that process can be found in this video: https://www.youtube.com/watch?v=YwcfqBEx.... Alternatively (since this repair is pretty difficult), you could search for a microsolder profressional in your area or return your iPhone to Apple for repair. However, if you DO NOT see any of the gray bars (as seen in the first video), the problem could be the FPC connector. Although it seems a bit unlikely, since the malfunctioning of the touch screen isn't consistent (if the pins on the FPC would've been broken, some rows or columns would be permanently non functional).

Normally if you have a SIM card in and are able to connect to a 3G network, you should be able to activate. If your iPhone says "activation currently unavailable" or something like that, try connecting it to a computer and activating it through iTunes. It might fail too, but at least iTunes will give you a more detailled error on why the activation has failed. If we have an error message we can try isolate the source of the problem :)

A blinking battery indicator, combined with very quick discharge time, is usually a sign of a worn out battery. Laptop batteries tend to discharge faster after a couple of years of use, or won't hold a charge at all. Batteries that are often fully charged but left in the laptop while it's running on AC tend to wear out faster and usually won't give the laptop any charge whatsoever after a year or two. You could go search on eBay for a replacement by searching for the model number of your laptop or battery.

Might be a bit of a stretch, but I've seen this kind of behaviour once with a laptop that had a dying hard drive. Could you check if any of the SMART attributes are displaying warnings with GSmartControl? If any of the lines in the 'Attributes' tab are red, especially "Current Pending Sector" and "Reallocated Sector Count", your system could start to experience these 'hiccups' as it tries to re-attempt a failed read / write routine. You can download GSmartControl here: http://gsmartcontrol.sourceforge.net/hom..., the diagnostics screen looks like this:

Hi there Since you don't have the propper tools to open the device yourself, I suggest you take it to a local repair shop. I've had some similar complaints from customers after they dropped their phones in water. Sometimes the 'click mechanism' doesn't work because of corrosion on the contact points, which is easily resolved by applying some rubbing alcohol to them and carefully scraping away the corrosion. Other times nothing helps and the button needs to be replaced, which will unfortunately mean you'll lose all TouchID functionality. If you do want to attempt to replace the button yourself, there's an easy guide over here: Sostituzione del pulsante Home dell'iPhone 5s. The repair isn't difficult at all :) Best of luck!

A good place to start debugging a circuit is by looking at the SIM reader's pinout. SIM card readers have some voltages on their pins that should always be present in order to correctly detect and access a SIM card. The pinout (and some other useful info) can be found here: http://www.technoburst.net/2014/03/sim-cards-tutorial-part-1getting-started.html. You should measure the pins and see if their voltages are correct. If all the voltages are present, you could start looking for the GSM modem on the board, see if that's getting power on its Vcc - pin, check if the trace to the antenna isn't interrupted, see if there's any kind of damaged filter in the way (some antenna's are used for multiple things, for example, the iPhone 4S uses one antenna for Wi-Fi and GPS signal and separates the two frequency bands with a filter. If that filter is broken, the signals are mixed and won't be received propperly by their respective chips). Unfortunately, I don't know exactly where all the chips on the board are (and...

Hi there Looks like you and your friends managed to break the LCD display. The screen of an iPhone is basically composed out of two layers: an LCD / digitizer (the actual display and touch screen of the phone) and a protective glass layer that goes on top. Cracks in the LCD always result in these black spots, flickering lines or no image at all. Replacing your front panel is easy. You can find a replacement screen on the iFixit store here: iPhone 5s LCD and Digitizer and a replacement guide here: Sostituzione LCD e digitizer dell'iPhone 5c. Good luck!
