Forum Moderator OneDrive, Support Engineer. Tom Griffith I hope you have found a solution to this problem already. I swapped in a different logic board and both my displays are working fine. I thought if I clicked on it, it'd toggle whatever setting it is it uses to actually turn it off, and I could use that to turn it on. So, i'm a bit lost here, i read the thread and was wondering if anyone can tell me the location of backlight fuse on this model so that i can test if it is burned or not.
The liquid spills might relate to water, juice, tea any liquid it may damage your internal circuitry very badly. I can see the icons when I press f5 and f6, but nothing works. A number of Apple's portable systems come with a backlight that illuminates the keyboard for easy viewing in dark environments. The Apple updating loading screen came up and then I was back to the home screen and logged in. Clever use of conductive ink. I'm 99% sure it has to be software related as when you enter system recovery for example, trackpad and keyboard work just perfect.
Simply shut down the system and plug-in to the power supply with original charger. Hardware problems per Apple 5. Otherwise, it might lead to other internal damages turning into a greater issue. Is this a software or hardware problem? I can see the screen with a flashlight and the machine works fine with external monitor. Removed them to my desktop and rebooted but it still freeze. I would like if you could help me too.
I do have the schematics but i dont have the board view so its getting hard to find the components. Just so I understand clearly. I'm still looking for the solution. I tried the command + option + p + r after I shut my MacBook down, and then saw my screen turn this weird shade of aquamarine, and I totally freaked out and turned the power button back on. Anybody know where to start testing for this. I've looked and the only place that may have had an answer is not longer posted it was not on this forum. Apple needs to address this publicly or in a software update.
Then, I realised the trackpad stopped clicking sometimes. Took me from a Zero to a hero in no time. When the MacBook is on you should see 3. I have asked apple for helped and we have gone through all the steps resets etc, but it still is not working apple said that it is a hardware problem.

The Autoupdate feature was on and it automatically updated from version 10.
I don't know if the problem will reapear but definetly the issue is located there. I have Macbook A1278 with 820-3115-B motherboard after water damage. Please von I'm inclined to beleive a transistor has failed, probably all 4. Funny, never had these issues on Mavericks or Yosemite. Do you guys think it has to do with the u9560??

Please help me with backlight and connector. . Delete all the files on your desktop 2. I would like if you could help me too. I plugged in a different display assembly to it and it was working fine so I assumed the logic board was fine. By the way, It looks like I finally fixed my 13 mbp with the backlight problem, there was corrosion buildup near the white cap at the battery connector, effecting a dime size around it and some nearby components. If this has been set on your system then you will need to press and hold the Fn key on your keyboard in order to use the built-in backlight controls on the F5 and F6 keys.
If the backlight appears to be stuck then resetting the controller should hopefully clear the problem. Normally the built-in functions are the default functions when pressing these keys, but this behavior can be reversed in the Keyboard system preferences. Any significant events before the issue started? Maybe something is wrong with the wireless as well. If that still doesn't work, then I would go back to them. So even though this machine is less than a year old and under full Applecare, this is not covered.
