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.

SONY XPERIA M2 – DISASSEMBLING PROCEDURE – HOW TO REPLACE THE LCD DISPLAY –MOBILES AND SMARTPHONES REPAIR AND SERVICE

Sony Xperia M2 – Disassembling procedure – How to replace the LCD display –Mobiles and smartphones repair and service

Be careful, the Cover is plastic.
Use a small suction cup and plastic tools for separating the Rear panel.
Before installing the new cover, you must clean the phone from the old adhesive tape and install a new one if your spare part has come without double sided adhesive tape.
Disconnect the Battery Cable.
The battery is stuck to the phone fame. Use the white tape to remove it.
Li-Polymer Battery, 2230 mAh Part number: LIS1551ERPC
Remove the SIM and the memory cards.
Remove x4 T5 Torx Corner screws & x2 T5 Torx Screws on the Board
Disconnect one by one: Touchscreen flex cable Proximity sensor flex cable Power on, Volume buttons cable SIM & Micro SD flex cable Coaxial antenna cable
Disconnect the LCD Display flex cable. The connector is on the other side of the board, under the Power/Volume buttons flex cable connector.
Put one plastic spudger between the Logic board and the Main frame.
Step one: move aside less the left side of the board - down.
Step two: the left side of the Logic board must go out of the main frame.
For this manipulation use only plastic tools.
Let's first test the new spare parts.
Use a scotch tape for the broken glass.
Unstuck the LCD Display flex cable from the Main frame.
Now preheat the glass before removing. This will soften the adhesive and will make separating more easy.
You can use a hairdryer.
With a cutter, make a room for a plastic tool, then continue with separating the Touchscreen & LCD Display from the frame.
This is the Display Assembly.
The LCD Display and the Touchscreen are not firmly bonded, while some other other models.
If your Touchscreen or LCD Display is OK, separate them carefully.
In our situation, both of them are broken.
Clean the frame from the remains of tape.
Install the LCD Display and the flex cable on its correct place.
Could not find adhesive sticker for this model, so used universal adhesive tape 3M – 3 mm.
Don't forget to remove protectors from the LCD Display and from the inner side of the Touchscreen.
