Macbook Air backlight water damage repair

We received a macbook air in from a new customer who had attempted a diy repair after spilling a glass of wine on it.
The customer knew about electronics so decided to attempt to repair it themselves. They had let the wine dry out and cleaned the motherboard with pcb cleaner. After cleaning the macbook would still not power up. they had checked the battery and that was fine, so from there they where a bit stumped.
They brought it in for us to have a look at and i was able to disconnect the battery and plug the charger in to force the macbook to boot, we heard a chime but had nothing on the screen. Next we connected an external display and could see that the macbook was powered on. We had no response from the keyboard or trackpad.
Next we took a look at the motherboard to see if we could visually find the cause for these issues. We noticed that the LVDS FPC (screen connector) had corroded and a few of the pads where no longer connected to the connector so this needed replacing. We disconnected the cable from the connector and tested for voltage which we got, so we replaced the 30 pin LVDS FPC.
We also checked the cable which looked corroded on pins 20 & 21. This meant that we had to remove the screen bezel, hinge and cover to be able to replace the cable. For us this is an easy job and requires patience and practice to be able to do this without causing further damage. Most repair shops will just replace the whole screen at a high cost instead of doing this.
We proceeded to disassemble the screen then found that the LVDS FPC on the bottom of the screen was also burnt on the same pins meaning that this would need to be replaced as well as the cable.
Next we checked to see why the keyboard and trackpad where not working. We found that the keyboard would need to be replaced and that the trackpad had corrosion on the connector which just needed cleaning to fix it.
We then quoted the client who was more than happy to go ahead as the costs where far cheaper than replacing the macbook. Within 24 hours of acceptance the macbook was back in one piece and fully working.
Another successful repair and another happy customer.

If you have had an accident with your macbook and apple have quoted to replace your motherboard please get in touch, we can save hundreds on repair costs by repairing your board rather than replacing it!

Macbook pro 2010 backlight repair

This week we received a macbook pro 15” 2010 from a regular customer of ours.
It was sent in for a backlight repair after water damage.
Our customer has already cleaned the board but this has not resolved the issue.
When we received the device firstly we make sure that it boots and shows a display on an external monitor, which it does. Then we do the torch test to make sure that the fault is no backlight and not no display. We can see the apple logo so we know that the image is being displayed and we are up against a backlight problem.
Next we open the macbook to inspect the board around the LVDS FPC (screen connector), we can clearly see 2 pins that are burnt out (pins 20 & 21) which are responsible for sending voltage for the backlight to the screen. We could see that the connector was burnt out, which would need replacing. We then removed the lvds cable (cable from motherboard to screen) from the connector to check this and this seemed fine from visual inspection. Next we powered on the macbook to check the voltages getting to the lvds connector. The backlight voltages where not present so we disconnected the battery and tested the fuse which was blown. After replacing voltage was restored so we knew that we should just have to replace the connector to have the clients macbook back up and running.
We applied leaded solder to the 30 pin LVDS FPC to lower the melting point of the alloy. Next we used our hot air station to heat the connector and remove it. We then cleaned the pads and surrounding area, and lined up the new FPC. After this we applied new solder to all of the joints, cleaned again and checked the connections.
All looked good so we reassembled the macbook and powered it up. The screen lit straight up proving that the repair had worked as expected.

We repair macbook boards on a daily basis, often after apple have quoted hundreds to replace the board itself rather than repairing it. Backlight problems are very common, along with no image, graphics faults and power issues. If your experiencing any issues with your macbook please feel free to get in touch
