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.

HOW TO REPLACE THE CASE OF APPLE MAC MINI

How to Replace the case of Apple Mac Mini


Apple Mac Mini:  CASE REPLACEMENT PROCEDURE 
Place your thumbs in the depressions cut into the bottom cover.
Rotate the bottom cover counter-clockwise until the white dot painted on the bottom cover is aligned with the ring inscribed on the outer case.
Tilt the mini enough to allow the bottom cover to fall away from the outer case.
Remove the bottom cover and set it aside.
Remove the two 11.3 mm T6 Torx screws securing the fan to the logic board near the antenna plate.
Lift the ear of the fan nearest the RAM up off the standoff secured to the outer case.
Lift the fan out of the mini for enough clearance to access its connector. Carefully pull the fan cables upward to lift the fan connector up out of its socket on the logic board. Remove the fan.
Remove the single 3.5 mm T6 Torx screw securing the cowling to the heat sink.
Lift the cowling from the end nearest the antenna plate.
Rotate the cowling away from the outer case and remove it from the mini.
Remove the following screws securing the antenna plate to the mini:
Two 6.6 mm T8 Torx screws
Two 5.0 mm T8 Torx or 2.0 mm
Hex screws (either will work)
Slightly lift the antenna plate from the end closest to the RAM.
Carefully pull the antenna plate straight away from the circular rim of the outer case.
Do not remove the antenna plate yet. It is still attached to the AirPort/ Bluetooth board.
Use the tip of a spudger to carefully pry the antenna connector up off the AirPort/Bluetooth board.
Remove the antenna plate from the mini.
Remove the following three screws: One 5.0 mm T8 Torx or 2.0 mm Hex screw (either will work)
One 16.2 mm T6 Torx screw
One 26 mm T6 Torx standoff
Carefully pull the wires for both hard drive thermal sensors upward to lift their connectors up and out of the sockets on the logic board.
Use the flat end of a spudger to pry both the hard drive and optical drive connectors up out of their sockets on the logic board.
To disconnect the optical drive thermal sensor, pinch its cables between your thumb and a spudger and pry the spudger upward to lift the connector up and out of its socket on the logic board.
Use the tip of a spudger to lift the IR sensor connector up and out of its socket on the logic board.
To remove the logic board, two cylindrical rods must be inserted into the holes highlighted in red. Inserting instruments into any logic board holes other than the ones highlighted in red may destroy the logic board.
Insert a Mac Mini Logic Board Removal Tool into the two holes highlighted in red. Be sure it makes contact with the outer case below the logic board before proceeding.
If you don't have a Logic Board Removal Tool handy, you can use two tools having a maximum diameter of 2.5 mm instead. Just insert one into each of the highlighted holes.
Carefully pull the tool toward the I/O board. The logic board and I/O board assembly should slightly slide out of the outer case.
Cease prying when the I/O board is visibly separated from the outer case. Remove the Mac Mini Logic Board Removal tool.
Simultaneously push the two plastic clips on the far left and right sides of the I/O board toward the middle of the I/O board and pull the I/O board away from the outer case.
Pull the I/O board/logic board assembly out of the outer case enough to access the power connector.
Use a pair of tweezers to disconnect the power cable from the logic board.
Pull the power cable connector toward the optical drive opening.
Carefully slide the logic board assembly out of the mini, minding any cables that may get caught.
Remove the 7.9 mm T6 Torx screw securing the power supply and optical drive to the outer case.
Pull the silver metal AC-In socket retainer away from the side of the outer case and remove it from the mini.
Rotate the AC-In connector 90 degrees counter-clockwise.
Slide the power supply out of the mini, minding any cables that may get caught.
Remove the hard drive from the mini, minding any cables that may get caught.
Remove the 7.9 mm T6 Torx screw securing the optical drive to the outer case.
Slide the optical drive out of the outer case, minding any cables that may get caught.
