If you're talking about macs repairs specifically logic boards repairs you need: 1- knowledge of basic electronics, how the circuits works, components knowledge how they work in a circuit. 2- learn how to read and interpret schematics. Download the popular macs schematics and boardview files and software (Open Boardview (free), FlexBV (Paul Daniels excellent software, must buy license). 3- Tools: hot air station, good solder iron with fine tips, multimeter, microscope, computer to read schematics, and many little accessories (flux, jumper wires, air extractor, tweezers, etc) 4- Watch a lot of youtube videos: Louis Rossmann is the reference for macs logic board repairs. 5- Practice on dead boards to learn the good technics. 6- Lot of time and patience before being good at it but what a joy when you get your first fan spin. 7- The latest Macbooks models are harder to repair so I don't know if there's a future in the macs repair ???? Good luck !!

Open the macbook, disconnect the battery, disconnect the screen cable from the logic board and check for any corrosion or discoloration on the end cable or on the LVDS socket pins. Also pay attention to the components in the socket area. If everything seems normal and you get a signal on an external monitor then you can assume your retina displays is faulty.

The only way to make this MBP work again is to deactivate the AMD graphic chip and run only with the Intel graphics. Then you'll get the same performance than the 13" MBP 2011. I bought the Tiresias module from CMIzapper (www.CMIzapper.com) and installed it on my MBP 17" 2011 with success. This small module is soldered onto the MBP rom chip and bypass the AMD chip. Check the procedure on their web site: http://www.cmizapper.com/products/tiresi...-gpukiller.html

Hi Robert. First action to take with a liquid damaged computer is to switch off electricity to the logic board so you have to remove the bottom cover and disconnect the battery. This would greatly help to stop the corrosion on the internal electronics. Rice is not a efficient method to remove humidity inside the laptop. Here’s what a technician would do to your liquid damaged Mac. 1- disconnect charger from the laptop. Don’t try to start it up. 2- Remove the bottom cover and disconnect the battery. 3- Remove the logic board for a visual inspection both sides checking if liquid has reached the logic board. If no liquid, liquid traces, corrosion on the board you should be ok with it. If there’s liquid or stains on logic board (or on other internal parts) should be cleaned with isopropyl 99% alcool. 4- Top case should be placed in a dry and warm area with a fan blowing air to it to remove humidity 5- There’s a good probability that the keyboard must be replaced cause tea may have corroded the small traces...

easy to find on ebay with this search “Macbook Pro A1278 key”. You can also contact a ebay seller in your area who deals with Macbook parts and ask for the key. If your keyboard is not in good condition you can also replace the whole keyboard, not to difficult on your Macbook model. Be aware that there are different key models on the A1278 so you better take a high resolution pict of your key white plastic mechanism and send it to the seller.

It seems you have a short on one connection. You could disconnect the hard drive and the LVDS (video) cable and start the iMac to check if the lights are stable.

Try to remove the lower ram stick from its socket and run the computer only with the upper ram stick. Let us know if the problem persist.

It’s the socket for the left speaker similar to the fan socket. It can be soldered back to the board if you find the part. You can harvest it on a Macbook donor board or buy it on eBay. Any tech can solder back the socket for cheap, only six micro solder to do on this part. Don’t try to glue it on the board, the 4 front pins must make a good contact to the pads and only solder can be used in this case.

I don’t know if it’s the problem with your MBP but the retina 15” 2012 (board 820-3332) has a well documented issue with IC U8900 on the logic board. The pins around this chip loose contact with the pads causing all sort of issues. A micro soldering job on the pins is necessary to regain board functionality. Do a search on Google for “U8900 repair”.

Remove the ram stick from the lower slot and try the computer. This is a well documented ram issue with the MBP 13” 2012.

I found a good way to remove the LCD without breaking it. Once you finish to clean up around the LCD just lift a bit one of the white metal backing plate and insert in the gap a plastified playing card under le LCD and slowly make your way to the center of the LCD. Repeat on the other side and the LCD will lift up intact.

to remove and put back the ribbon cable in its slot I use a piece of scotch tape. Easier to remove or insert the cable in the slot.

Since this kind of connector and very fragile and easy to damage even with a spudger I use a needle that I insert in the front side of the connector, between the connector and the socket and only apply a little pressure while lifting up the needle. The connector will then pop up from one side. Repeat the procedure for the other side. With this method it's impossible to damage the connector. I adopted this method after ruining two or three connectors using the spudger.
