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.

OPPO X9000 OPPO MOBILE PHONE DISASSEMBLING PROCEDURE -

Oppo mobile phone disassembling procedure - Oppo X9000

Turn the phone over so that you are facing the back side of the phone.
With your fingers, pry the back cover up starting from the top of the phone near the headphone jack and camera.
Completely remove the back cover by moving down the sides and bottom with your fingers.
With your finger, remove the battery from the phone by gently lifting the top-right corner nearest to the camera.
Remove the twelve exposed 3.6 mm Phillips screws on the rear of the phone using the 3.6 mm Phillips screwdriver.
Store all the screws in a safe place where you will not lose them.
Remove the three circular rubber screw covers on the back of the phone by slipping the spudger into the border between the rubber cover and the chassis. In one motion, pry the stopper out of the hole. This can take some force.
With the 3.6 mm Phillips screwdriver, remove the three newly exposed 3.6mm Phillips screws.
Insert the plastic opening tool underneath the chassis near the power button and pry the chassis from the phone. This should take a little force.
Use the sharp end of the spudger to pry the power button bracket from the side of the rear case.
Rotate the phone onto its side so that the power button falls out with ease.
Make sure not to lose the power button.
Use the sharp end of the spudger to pry the volume button bracket from the side of the rear case.
Rotate the phone onto its side so that the volume button falls out with ease.
Make sure not to lose the volume button.
The motherboard is split into two different chips. The large chip is located above where the battery rests and the smaller chip is located below it.
Remove the three 3.6 mm Phillip's screws on the motherboard.
A small silver piece of metal is connected to the lowest screw and may fall off. This metal holds the WiFi antenna in place and should not be lost; although the phone operates just fine without it.
Using the flat end of the spudger, pry the four tape connectors straight up out of their respective motherboard sockets.
This connection is a little bit more tricky to remove. Follow these directions carefully to avoid damaging the device.
On the right side, there are two motherboard connections hidden underneath the motherboard.
For these, insert the spudger in between the motherboard and the connection and rotate the spudger in a rocking motion until the two cables are disconnected from the motherboard.
Like the last step, this connection is tricky to remove. Please pay close attention to the guide to avoid damaging your device.
On the bottom right only one connection is visible, however an additional connection is hidden underneath the first. To safely disconnect both, first unplug the visible connection then lift its tape up to expose the second socket. Similarly disconnect the second tape.
With your fingers, gently pull upwards on the WiFi antenna near the connection on the smaller motherboard until the antenna is no longer connected to the bottom motherboard.
Use the spudger to carefully pry the small motherboard off of the phone.
Start from the sides of the lower motherboard closest to the charging port. Carefully pry the motherboard off until it is no longer connected to the phone.

Use the spudger to carefully pry the bigger motherboard off of the phone. Start from the top of the large motherboard. Carefully pry the motherboard off until it is no longer connected to the phone.
