REPAIRING AND NOT THROWING AWAY

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

SAMSUNG GALAXY S5 HOW TO REPLACE THE MICRO USB PORT - DISPLAY REPLACEMENT PROCEDURE


 SAMSUNG GALAXY S5 HOW TO REPLACE THE MICRO USB PORT -  DISPLAY REPLACEMENT PROCEDURE   
Samsung Galaxy S5
DISPLAY REPLACEMENT PROCEDURE 
Insert a fingernail or plastic opening tool into the divot to the left of the rear-facing camera. Gently pry and twist the flexible rear cover off the back of the phone.
Insert a fingernail or plastic opening tool into the recess in the bottom right corner of the battery and lift upward. Remove the battery away from the phone.
Using a fingertip, pull the microSD card straight down out of its slot. Remove the microSD card from the phone.
Repeat the above procedure to remove the SIM card.
Use a plastic opening tool to pry up the plastic mid-frame connector panel. Remove the connector panel with a pair of tweezers. There should be enough adhesive to re-adhere the panel upon reassembly, otherwise use a small amount of double-stick tape.
Use the sharp tip of a spudger to pry the home button cable connector straight up off its socket.
In the following steps you will be using an opening pick to separate the adhesive securing the front panel glass. Only pry where directed. If you experience resistance, stop sliding the opening pick and reapply heat. Insert the edge of an opening pick underneath the bottom right side of the front glass.
Slide the opening pick up along the right side of the display
Carefully slide the pick around the corner, stopping before the speaker grille at the top of the phone.
The adhesive securing the top of the phone is only a narrow strip above the earpiece speaker. Slide the pick along the top of the speaker to avoid damaging internal components. Slide the opening pick across the top of the phone, being very careful not to insert the pick too deeply.
Carefully slide the pick around the upper left corner. If you encounter any resistance from cooling adhesive, reapply a heated iOpener to the left side of the phone.
Slide the opening pick down along the left half of the phone stopping at the lower left corner.
Slide the opening pick all the way to the bottom left corner of the phone, making sure it is securely placed. In the following step you will be placing an iOpener over the home button end of the phone, you won't want your opening pick to slip out.
The bottom end of the phone contains the soft button and home button ribbon cables. If you insert the opening pick too far into the phone you risk cutting these cables. Slide the very end of the opening pick across the bottom edge of the display to separate the last of the remaining adhesive.
Twist the opening pick to detach the glass from the phone. If the front panel does not detach easily, it may require additional adhesive cutting.
If the front panel is not easily freed, the adhesive on the soft button cable may need to be separated. These cables are thin and easily damaged, therefore be certain you are only peeling them off the display assembly and not lacerating them. Insert an opening pick under the soft button icons on the display and pry the button cables down off the inside of the front panel.
Slightly lift, but do not remove, the home button end of display assembly. Do not remove the front panel entirely. It is still attached by a connector. If you are reusing the home button flex cable, be careful not to sever the cable from the home button. Adhesive can cause the cable to rip apart from the home button. While the home button will still work, the fingerprint scanner will not.
Use the sharp tip of a spudger to lift the front panel assembly cable connector straight up off its socket on the motherboard. Safely remove the front panel assembly from phone
Remove the ten 3.4 mm Phillips #000 screws from the display side of the midframe.
Flip the phone over and remove the following screws from the battery side of the midframe: Two 4.4 mm Phillips #000 screws near the USB port on the battery side of the phone
One 4.4 mm Phillips #000 screw
Gently run a plastic opening tool down along the left inner side of the interior frame to separate the three white plastic clips.
The mid-frame is composed of two halves that encase the motherboard. Gently pull the long sides of the silver bezel out away from the phone to separate the two halves of the mid-frame. It may be helpful to gently push in from the inside of the battery compartment, but be careful not to flex the interior half of the mid-frame, as the motherboard is mounted to it.
Continue on to the right side of the silver bezel, pulling away from the interior section of the midframe to separate the two halves.
Use a plastic opening tool to pry any remaining corners out of the silver bezel.
Carefully remove the interior midframe/motherboard assembly from the white inner midframe.
Carefully wedge the tip of a spudger underneath the antenna cable connector. Delicately lift the spudger directly upwards to disconnect the antenna connector off its socket on the motherboard.
Remove the single 3.0 mm Phillips #000 screw securing the motherboard to the midframe.
Pull, but do not remove, the camera end of the motherboard up from the midframe to allow access to the connectors on the rear. Do not attempt to fully remove the motherboard as it is still attached to the interior midframe by the Micro-USB port daughterboard connector.
Use the flat end of a spudger to pry the daughter-board connector straight up off its socket on the motherboard.
Micro-USB Port Daughterboard
The soft button ribbon cables are attached to the Micro-USB port daughterboard and must be detached from the interior midframe.
Use the flat end of a spudger to carefully peel the soft button cables up off the interior midframe.
Flip the midframe/motherboard assembly back over.
Remove the single 2.5 mm Phillips #000 screw securing the Micro-USB port daughter-board to the mid-frame.
Gently slide the flat end of a spudger in between the daughterboard cable and the interior midframe to begin to separate the adhesive holding it down.
Rotate the midframe/motherboard assembly and reinsert the spudger between the daughterboard and interior midframe.
Twist the spudger to separate the last of the adhesive between the daughterboard and interior midframe.
Remove the daughter-board from the interior mid-frame.
