I'm not completely convinced my logic board is broken... Need second opinions!

I can't recall the specific specs of my Macbook Pro, but it's a 15 inch unibody that I purchased in August 2011.

About a month ago, I spilled water on it. I followed all the right steps, unplugged it let it dry out, etc. but when I took it to my school's IT desk they told me it was damaged. However, they seemed to think it was only localized to the area that controls the LED screen.

I sent it into iResq to have it repaired and they told me I needed to have my display cable replaced in addition to my logic board and that the repairs would cost me about $1100.

I haven't taken it to the Apple store yet, but I'm just curious as to if it actually IS my logic board that is broken. When I turn it on, everything runs just fine. The keyboard lights up, I can hear the hard drive whirring, and there's no problems with the USB or charger ports. The only thing that appears to be wrong with it is that my screen is dead. BUT if I shine a flashlight on it, I can see the screen perfectly! It looks just like it normally would.

SO is this still a logic board problem or something else?

Have you tried hooking it up to a monitor? see if that work. Im not 110% sure if the same wiring harness thats used for the 'onboard display' effects the display port. its worth it shot, if it works fine on a monitor/display then chances are the logic board is just fine.

Hi and welcome to the forum Sarah.

If i was you, i would be looking at hooking it up to a external monitor first and see if the Machine is working. This way you can see the OS try the keyboard and more trouble shooting if need be.
If it works on a Ext Monitor then it isn't the Logic Board.
HTH

Okay thanks! I'm sorry, I'm kind of inept when it comes to computers, how would I hook it up to an external monitor?

Assuming the side of your MacBook Pro looks like the above picture, you will have to get a Thunderbolt cable (should have been provided i believe) and connect that to an external monitor, or TV. Chances are you will need an adaptor either to go to VGA/HDMI/DVI.

Im not 110% sure what comes with the 2011 MacBooks, I dont have a thunderbolt drive, but that is the port to hook up to an external monitor. Match the input port on the monitor to an adaptor that will allow you to use the thunderbolt port. I promise is not as complicated as i just made it sound lol

I would try it on an external display, but if you can see if find with a flashlight on the display then it's the part that powers the LCD's Backlight that is messed up. That also usually plugs into the Logic board, so it still could be the board.

And a board is a complete prefabricated unit ~ no bits and pieces. All or nothing. And having spilled liquid it is quite a reasonable diagnosis alas.

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

I agree with Harry. If iResq said the logic board needed replacement, it likely does. They're a very reliable authorized Apple repair service and would not have made that recommendation otherwise. The problem with spills is the long term damage that shows up later due to corrosion and other problems that surface.

agreed, That is why the Backlight is getting no power since it all plugs into the Logic board.

just had someone spill liquid into my iBook G4 that has been a faithful friend. Some got into the Logic board. I was out of the room. came in and yanked the power and battery and tried to save it but parts on the board were blown from the liquid. Sad but it's gone.

LVDS cable connector probably has blown pins. I have seen many times, small amout of fluid trapped between cable connector and socket.
Socket is fixed to board so not a replaceable item.
I would use an otoscope, or magnifying glass to view LVDS connector on board first to be certain of the blown pins, they will be blackened or copperish colored not the tin silver they should be. If all silver, then I would view LVDS cable connector pins, should be gold, if blackened then cable replacement would do the trick. If pins are gold then inverter has blown, replace the screen.

Sorry to hear that Dennis. The iBook G4 has always been one of my favorite Apple machines. The only thing that compares with it for size and compactness today is the MacBook Air.

So exactly the same thing happened to my daughter's 13" white unibody at college. I had her turn it upside down to drain out as much water as possible and then not turn it back on until she could take it to an Apple dealer. Of course, they just immediately told her it was not ever going to work again and that she would have to buy a new one.

When she brought it home several weeks later, I powered it on and it worked - at least for a little over a day. The next morning, I nada the same problems with the screen that Sarah did. The screen was actually displaying data, but no backlight. Here's the weird thing - if I remove the battery and run AC power only, it works perfectly!

Thoughts? I hate to just spend $500 on a logic board when it seems there could be something else wrong here. Our local PeachMac stores won't touch it, lol.

My niece spilled water on hers, it wouldn't work. She took it to the Apple store and told them the truth, she cried and said she needed it for work and told them her boss was going to kill her because her boss wanted her to buy her a Windows PC and she complained until they bought her a Macbook Pro, they fixed it for free. Can't say it's going to work in your case, but...............

Often, little parts of the logic board can get toasted. It might be the teeny tiny bit that controls the LED backlight, but that doesn't really matter.

If you can get it to run on an external monitor (maybe even take it to an apple store and see if they'll hook it up to a apple display for you) then I'd say you probably have yourself a really nice desktop.

I totally agree with chscag, though. You are likely to see long-term problems.
