replacing iPhone feature
future iPhone
As irepair tech outstanding Muhammad Asif Azeemi has said: A iPhone that is vibrating with no display when powered by outsourcing this fault is a nonfunctional LCD display.
iPhone accepted  "power supply " but show vibration or sound
If your Apple iPhone shows no display (no backlight, no image when you try to charge its battery), and does not seem to be working when you insert charger show USB icon on LCD. When connected to an outscore power supply then iPhone endlessly repeats twin vibrations in 'silent' position.

When iPhone backlight Circuit or IC Failed

In iPhone circuit, You may have a backlight filter components(like a fuse). (This can easily happen when using certain replacement LCD that have an exposed backlight flex solder joint pins—pressing the digitizer into the frame will cause the exposed pins joints to short the LCD power line to ground and burn the filter and its components.) This can also be fixed as a board-level repair.

Software Problem in iPhones

If your iPhone has never been opened, the issue could be a simple iso software crash. Perform a force restart resolves it.

When LCD Cable(s) Disconnected

Your iPhone screen's flex cable connectors may have popped free after a drop. to fix your iPhone's screen check each connection and re-seat it if necessary.

When LCD Panel Cable(s) Damaged

Check LCD flex cables—in particular, the display's flex.  carefully Inspect cables for damage. replacing the LCD panel can solve the problem.

When LCD Cable Connector Sockets Damaged

There may be damage to the Screen digitizer flex cable socket on iPhone Circuit board. Check the digitizer sockets for debris, bent connector pins, and remedy the problem. If the socket connector or some pins is damaged, an advanced smartphone repair course skilled technician can replace it with a board-level repairing.

Section iPhone Repair Knowledge

1, fault classification
1, caused the causes of iPhone
(1), the menu settings failure: failure is not, strictly speaking, if no calls are perhaps for the owner to set up call forwarding; play no iPhone is set up outbound throttling. The baffling problem, first with total reset.

(2), using failure: improper operation generally refers to the user, dislocation caused by adjustment. More common are the following categories:

1), mechanical damage. As the operation or method of application of excessive force is not correct, resulting in apple devices rupture, deformation, and the module pin loose weld failures and other causes. In addition, flip off axis, the antenna was broken and thrown split casing, water, broken screen, also belong to this type of failure.

2) improper use. When using the phone's keypad keys with the nail tip will cause the keyboard touch bare ground or even fall off; with bad iPhone charger will damage the internal charging circuit; even cause the accident; on the phone menu for illegal operation of certain functionality is turned off, the iPhone is not working; error led to SIM card password locked, the blind try to create self-locking SIM card protection.

3) improper maintenance. Apple iPhones are very sophisticated high-tech electronic products, use should be noted that in the dry, the temperature suitable for the use and storage environment.

4), the quality of failure. Some parallel imports of previous iPhones are through consolidation, converted, quality underground. Although some mobile phones are digital phones but do not meet the smartphone standard, cannot be used.

Fault Classification in iPhone

(1) does not dismantle the iPhone only to see its appearance from the mobile phone failure, can be divided into three categories:
1) The first one is not working, including the power supply can not turn connected to the phone and press the power switch without any reaction;
2) The second is not completely boot, press the iPhone to switch current can be detected, but no switch machine normal reminder: if key lighting, display lights all bright, display, character information display with ringer After the start tone adopted by such self-test;
3) The third is to boot, but the failure of some functions, such as the buttons do not show unusual, silent, do not send it.

Learn to Repair Smartphone Printed Circuit Board Step by Step part two

6 Jan 2018
As I told you in my previous article the PCB printed circuit board cannot be repaired in two situations
  1. when it burns
  2. and second When It Breaks

when it breaks the copper wire gets disturbed otherwise,
printed circuit board
copper wire inside

in the burn case,
mobile circuit

we see that how much it burns if it burns too much then you cannot repair it.and if it burns just little more then you will try to fix it.

Q: How Can It Be Fixed?

A: we will know it by using the meter!
digital meters

you will have to keep the multimeter on continuity if the phone is short it will give reading from both sides on the battery connector of the phone.
multi meter leads
battery connector of the phone

and if the phone is not short that you will not get reading on multimeter form the battery connector on the I told you the meter should be in continuity and if you are using the digital meter then put it on continuity buzzer.
meter position
digital meter continuity buzzer

placed the black lead from the meter on the positive side of battery connector and red lead on the negative side if reading shows
mobile short reading
same reading both side

by the opposite banking then it means there is a shortage in the circuit remember one thing! all the reading shows the amount of burning area in the circuit for example if the opposite shows
opposite side reading
previous reading

it means the phone is 35% short or burn Similarly if opposite shows more than

it means the phone has been burn more than the previous reading if reading is zero from battery connector both sides then phone circuit cannot be repaired ever.

Block Diagram iPhone 6 Mobile Repair Step by Step for USB Circuit

31 Dec 2017
The data exchange system consists of:
Pmu: Integrated Nutrition
IC USB: Portal for communication between devices and processor

The U2 IC Scan Method:

It's also called the U2. The examination is being tested.
The reluctance of the iPhone 6 to be considered at the USB freight entrance points is not enough, but the poles should be changed every time on the test points until the diagnosis is correct.
Block Diagram iPhone 6 Mobile Repair
for USB Circuit

What can be deduced that ourselves on the Examination on one side:

- Black on the ground and red on the test point.what is infinite on the one hand does not mean that there is value in the opposite way, it may be infinity or very high value, and therefore a break in USB communication and you will not be able to detect it by limiting the examination on one
- Black on the point and red on the ground.
The value, on the one hand, does not mean that there is no end in the opposite direction because there may be damage in likes (the or the) or a diversion in an integrated course via Non-Polar Capacitors.
USB integrated circuit
way value data 

What can be deduced if the test is properly tested:

It is the same method of testing the iPhone 6 IC power on the battery contact points
And the same way the iPhone 6 sim is checked on the chip points.
And the same way the SD card is checked on the external memory points.
The reversal of poles is necessary to obtain results and conclusions that bring us closer to the right diagnosis.

First, let us agree that the values that appear to be sound and if we reverse the poles do not necessarily indicate the validity of the integrated, but it confirms the validity of the track (there is no leakage or short of the protection elements on this path).
The improper values are definitely indicated in the course or in the elements of protection or in integrated (the).

What can be caused by Damage: U2 IC USB

1) The first part of the supply charge and power failures;
2) The second for the smartphone software fault;
3) The third part of the fault for the phone transceiver.Between the three types of failure was inextricably linked,For example: impact of smartphone software, power supply systems, send and receive path phase-locked loop circuit, the transmit power level control, send and receive time-synchronous control channel,and send and receive access to reference crystal oscillator has to provide software for smartphone running the clock signal.

Increase Smartphone Maintenance Efficiency by Finding out Basic Electronic Components Failure

Following more useful Assignment: In the daily smartphone maintenance, to understand what factors lead to damage to the role? To understand the damage factors, should we do?Second, the failure characteristics of common basic electronic components whether the breakdown of natural wear and tear or damage arising from man-made failures, generally attributed to the circuit contacts open, damage to basic electronic components and software failures of three failures. Contacts open, if it is a broken wire, disconnect the plug aside, poor contact, etc., generally easier to repair them. Damage electronic components, (except obviously burned and fever), often difficult with observers found that in many cases, have to rely on instruments to detect judge, so the maintenance staff, the first essential to understand the various devices effectiveness of the characteristics of this smartphone circuit fault for the maintenance, increase maintenance efficiency is extremely important, the following gives some common characteristics of effective electronic components.

How to Check Polar Capacitor in Smartphone Circuit

7 Dec 2017
All smartphone non polar and polar Capacitor finding and Checking method are can use Digital and Analog Multimeter both to Check Capacitors in smartphone motherboards.

The Tantalum Polarized Capacitor

Tantalum polar capacitors are used in latest smartphone circuits. Tantalum Polarized Capacitors are typically used in large voltage mobile phone situations, such as Direct Current line filtering to reduce noise related to uneven DC voltage levels. Mainly value measured in microfarads. Polarity is critical to mobile devices.
Polar Capacitor Checking method is listed below with Digital Multimeter. Set Digital multi-meter on CONTINUITY Scenior1: Connect Black probe to Capacitor +VE print. and Red probe to Polar Capacitor -VE print shows some reading.

Note: Check Polar Capacitor with a Digital multimeter on Buzzer Mode. If it is good then the Digital multimeter will NOT give any Beep or Buzz sound. If there is the buzzer sound on Digital multimeter form both +VE and -VE side then the polar capacitor is faulty. Replace it with a new one.

Why Polarized Capacitor Short Lead

Polar capacitors can have an internal shorted terminals, excessive leakage, and degradation of capacitance meter. short the terminal capacitor to discharge it prior to testing.
