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!

HOW TO REPLACE THE OPTICAL DRIVE - APPLE MACBOOK PRO 15

How to replace the optical drive - Apple MacBook Pro 15


OPTICAL DRIVE REPLACEMENT PROCEDURE 
Remove the following ten screws securing the lower case to the upper case: Three 13.5 mm (14.1 mm) Phillips screws. Seven 3 mm Phillips screws.
Using both hands, lift the lower case near the vent to pop it off two clips securing it to the upper case. Remove the lower case and set it aside.
Remove the two 7.4 mm Y1 Tri-Wing screws securing the battery to the upper case. Note: For certain repairs (e.g. hard drive), removing the battery is not necessary but it prevents any accidental shorting of electronics on the motherboard. If you do not remove the battery, please be careful as parts of the motherboard might be electrified. You do not necessarily have to follow steps 3-6 to remove the battery in order to replace the hard drive. However it is recommended to remove all power sources from electronics before working on them.
Use the tip of your finger to carefully peel back the corner of the warning label to reveal a hidden Tri-Wing screw. Remove the last 7.4 mm Y1 Tri Wing screw securing the battery to the upper case.
Lift the battery by its plastic pull tab and slide it away from the long edge of the upper case.
Do not try to completely remove the battery just yet.
Tilt the battery away from the logic board enough to access the battery cable connector. Pull the battery cable connector away from its socket on the logic board and remove the battery from the upper case. Pull the battery cable connector away from the center of the logic board.
Use the flat end of a spudger to pry the AirPort/Bluetooth ribbon cable connector up off the logic board.
Disconnect the camera cable by pulling its connector away from the socket (toward the optical drive) on the logic board.
Use the flat end of a spudger to pry the optical drive connector up off the logic board.
Remove the two Phillips screws securing the AirPort/Bluetooth board housing. Carefully rotate the AirPort/Bluetooth board housing (with AirPort/Antenna cables still attached) out of the lower case.
Remove the following three Phillips screws securing the optical drive to the upper case: One 4.5 mm Phillips screw securing the optical drive bracket to the upper case near the fan.
Two 2.5 mm Phillips screws securing the optical drive to the upper case near the optical drive opening.
Lift the optical drive near its connector and pull it away from the upper case to remove it from the computer.
Pull the optical drive cable out of the optical drive. Be sure to pull by the edges of the connector, not by the cable itself. Optical drive remains.Transfer this bracket to your new optical drive or hard drive enclosure.
