Apple had quoted our customer as ever, an astronomical amount of money as they said it needed a new logic board. Upon plugging this in, it indeed would not turn on. Using a USB-C multimeter it showed the Mac was taking 5 volts, not 20 Volts needed to turn it on, or to charge correctly. Upon opening this up, apart from the battery being bad we found water damage on the only singe USB-C port it has. On cleaning up the port, there’s a ‘hole’ burned right through it beneath the gold pin.
We put in a replacement USB-C port (not entire logic board) a new OEM battery, and this guys is again taking 20 volts, booting and charging again as it ought, all at a fraction of the cost at Apple, and without needlessly losing all your data. Don’t delay, send yours in today !
This still very capable 2009 27″ iMac i7 with 16GB Ram was brought in with the no entry sign showing which means dead hard drive essentially.
We upgraded to a 500GB Solid State Drive and using a patcher installed OS Mojave to give this beast of a mac a good few more years yet. This iMac now boots in just over 20 seconds to desktop. Apple say no, Apple say it’s Antique. We give all Mac’s equal love here !
Macbook Pro A1502 – Mug of peppermint tea killed me!Brought in dead, and dripping with peppermint tea within an hour of the spill. The inital stages of corrosion had already begun, but due getting it to us straight away damage has been minimalised
After cleaning the corroded areas there were only two bad areas that needed work, Power to the CPU has been restored and S0 Rail, which is part of the circuitry that enables the mac to power on.
Upon proof of being an NHS worker shown, a 15% discount was given. Macbook up and running at a fraction fo the cost of Apple, happy customer!
2017 A1706 Macbook Pro touchbar – Killed by a fruit smoothie. Smells nice though! Mac would start initially and turn off mid boot, 4 USB-C ports not functioning – So no power in nor charge. The right hand pair of USC-C ports were wrecked. cleaned up connector , relaced 2 bad caps and cleaned up the others to restore USB to all ports. Next ( forgot before photo ) below the long connector, to the right we replaced 2 capacitors , 1 of which was hanging off the board – blown clean off. can see the red scorch marks around where it was replaced, that area is resposible for voltage to the CPU. Sorted. next a shorted Hall effect pad which is attached to the SMC, cleared that up, removed the short – Happy SMC. Cleaned up and tested, Keyboard cleaned up, put back together charging correctly and powers on as it should. Back to life at a fraction of the cost that Apple quoted.
A1502 2015 Macbook Pro cider spill. No power, no picture. What did they do to you little Macbook, what did they do? Cider got spilled through the keyboard.Then the worst thing one can do was done. It was placed in a bag of rice and put in the airing cupboard for a few hours, taken out again, plugged in and tried to turn it on again. This caused most of the damage. U5110 area was badly shorted to ground, this area is responsible for SMC reset – SMC is the sytem contoller that when it has all nessecary and correct info and parameters will allow the Mac to turn on. In the state of this, with it shorted to ground leaves the SMC in a state of permanent reset – Which means off! Had to replace a few caps and a resistor and run a wire to U5110 as the trace and pad were wrecked.
Next up, one reason for no picture to screen is the LDVS connection (the cable that goes from graphics output to the screen) being welded to itself and blown pins.Both the LDVS connector on the boards, and the cable from the screen had to be replaced.
Next, we have a very feignt picture now to screen, if we hold a bright light and shine it through the back of the screen through the plastic Apple logo, we can see the feignt flashing image of a folder with a question mark on the screen. Why this folder with question mark? Thats the Mac/ board fired up and booted sayingit cant find the hard drive or SSD to boot from, as we always remove the SSD/ HDD when working on these things to prevend any accidental damage to customer data.- So, the feignt image tells us there is no back light power to screen. The chip that controls this is U7700 – which essentialy take a 12 volt line and whacks it upto 50 volts, that’s what effectivley turns the screen on.
So U7700 replaced along with an iffy looking resistor, and we now have full image to our test screen. Our work is done, keyboard cleaned up, Mac put back together again, and we have one fully functioning Macbook Pro at a fraction of the cost of Apple. 🙌💪✊
1TB SSD (Solid state drive) came into us this morning, dead. Like dead dead dead. The machine it came from had been running quite hot. Upon plugging it into any other machine it prevents the machine from booting, and if plugged in via USB caddy to try and see if there’s any data also freezes the machine. A very dead SSD. So we removed it from its housing – Inspected the logic board for any obvious bad areas ( blown resistor or capacitor etc ) , saw nothing, tested with multi meter that circuitry was OK, upon inspecting the two large chips – that’s the actual memory where your data is written to, the solder balls around it looked grey and mushy, as would most very certainly be under neath too. These chips are soldered to the board by an array of sometimes hundreds of solder balls. Knowing it had come from a hot environment we knew it was likley bad solder under thses chips. So, using the correct temperature and pressure reflowed the solder. Look at the before and after pictures, grey solder blobs vs nice shiney solder balls. Cleaned up and plugged into a USB caddy, plugged into our recovery rig and the drive showed up and preseted itself with a corrupt partition table, using specialist tools & software this data is now being recovered to a new drive. 👌 #data#recovery#SSD#professional#open#righttorepair#apple#mac#macbook#dead#liquid#water#damage#repair#nearme#horsham#sussex#upgrade#vintage#service#local#fast#logicboard#fix#screen#replacement#lost#password#EFI#lock #imac #dead #hard #drive https://www.mycomputerworks.co.uk/https://macrehab.co.uk/
Water spill over Macbook Air A1466. As soon as the spill occured, the customer did all the right things. Turned it off right away and unplug it. Leave the lid open , turn the mac upside down and rest it keyboard down on a tea towel. Remove the back (pentalobe driver required ) and disconnect the battery. In this case customer carefully dried it out and cleaned what corrosion had started. Carefully dried it, waited 24 hours and turned it on to find working fine but keyboard doing crazy things. Apple quoted just over £400 with VAT ontop of that to replace the entire topcase – thats the casing, the keyboard, battery, track pad, keyboard backlight, keyboard, DC power in board, to name but a few when its simply the keyboard at fault here. So, we stripped the top case down to the chassis and removed the iffy keyboard and the gazillion tiny screws holding it in (corrosion on cable connector and bad stickey keys and a shorting caps lock !) . Put in the new, screwed back in a gazillion teeny tiny screws, fitted the back light, stuck the battery back in, and put the logic boards etc back into place. Fired up and used keyboardchecker.com to test all keys. All as it should be at a fraction of the cost by Apple to you and the environment. 🙌✊
Apple – ehem, cough ‘Genius’ bar fail & independant repair shop fail. iMac booting but dead screen. Apple quoted around £1000 for logic board replacement, independant shop quoted £550 for a replacement screen to be fitted. As ever when customer first called and asked for a quote – Was told can not quote for what it may not be. Can only quote once have seen the machine and positivley identified the issue. In this case it was just a blown fuse that needed replacing on the logic board. Try £260 rather than nonsence money for the incorrecct fix. 👍💪✊
A1398 Macbook Pro black screen – No image. Many mistake this as graphic card/chip failure, which it’s not! Some idiot will then reflow the graphics chip, which it didn’t need but in doing so it heats the voltage core chip enough , and just enough to reflow the solder on it back into full contact. This only lasts a few months. What we have done here is to resolder the vcore chip with nice new clean solder, we then reflow the circuit area around the vcore to ensure everything is in its place and won’t fail. Note the before picture the grey ball like solder blobs around the vcore chip, then after – whilst it was being reflowed, even through the flux its clear how much brighter the soldering is around the chip. And voila – We have a picture 💪✊🙌
Macbook Air A1466 Dead, no power no image no charge light. Apple had quoted customer for an entire logic board replacement at stupid £££. As we know, Apple NEVER repair anything, just swap out the entire inside at great cost to YOU and the environment ! Where here we fix it. These two corroded areas were responsible, corrosion removed, 2 capacitors replaced with one needing to be re-routed as the pads they are soldered to were toast ( the red areas ) – This area is responsible for allowing the Mac to power up. Secondly SPI MUX needed the track from resistor to MUX replacing at was burnt out also. This was achieved by running a small wire in its place, then coating it in conformal paint to insulate it. And there we have it, Macbook Air back to the client at a 1/4 of Apple’s quote. 💪✊🙌
