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!

HTC ONE X – DISASSEMBLING PROCEDURE – HOW TO REPLACE THE MOTHER BOARD

HTC One X – Disassembling procedure – How to replace the mother board

DISASSEMBLING PROCEDURE
Insert a safety pin, or other small  object in the small opening next to the Sim card slot to remove the SIM card.
The Sim Card Slot is located at the top of the rear panel.
Using a plastic opening tool, carefully separate the display screen from the rear panel.
The display assembly is a tight fit therefore the removal must be carried out carefully with firm, constant force being applied around the bottom corners and sides of the panel. Note that the top of the phone is underneath the panel, and will not come out.
If  your display is cracked, take extra caution when separating the display from the rear panel to prevent further breakage. Set aside the rear panel.
Remove the five screws at the top of the panel using a Phillips head screwdriver.
Two 2.05mm Philips head screws
Three 2.44mm Philips head screws
Also remove the screws with the warranty stickers.
Once the screws are removed, gently remove the plastic cover using a plastic opening tool to  detach the edges from the front panel.
Once you have disassembled your device, your warranty will no longer be valid
Remove the two screws at the bottom right corner of the front panel using a Phillips head  screwdriver, as shown in the image.
Two 3.35mm Philips head screws
Use tweezers to disconnect the antenna from the logic board to the PCB board.
Remove the tape connected to the motherboard.
Remove the tape holding the battery in place.
Gently lift the battery from the bottom using a plastic opening tool.
You may have to apply heat to melt the glue holding the battery in place.
Do not completely remove the battery yet
You can now disconnect the flex cable holding the PCB board place. Gently open the gates using tweezers or a plastic opening tool and use tweezers to slide the flex cable out.
Now that it's separated, remove and set aside the PCB board.
Place the battery back into its original position once the PCB board has been removed
Use tweezers to disconnect the power button flex cables.
Disconnect the volume flex cable by opening the gate and then sliding the cable out using tweezers.
Disconnect the touchscreen flex cable
Disconnect the remaining two flex cables in a similar manner before completely removing the logic board.
