    Hi guys,

    I'm new here but I've been reading through many of the posts. I spilled some sugarless tea on my macbook and the screen immediately turned off. The amount of liquid that spilled was small.

    It spilled in the top left corner of the macbook, what exactly did it spill on?

    I dried off the macbook, took out the battery, and used a blow dryer on cool for about 10 minutes. After this, I followed the sticky post's instructions and stuck in a sealed box with rice for 24+ hours.

    When I plugged it in, the macbook turns on and the screen flashes for a split second. It continues to boot up (you can hear the normal whirring), but the screen stays black.

    Did the screen fry? If so, why will it still flash for a split second on turning on? Any thoughts on what may be going and possible costs of repair?

    Thank you so much for the help; I haven't been able to find any posts that have this problem.

    -Pierre

    I have some advice that should help: Don't drink by your MacBook. Or eat.

    Repairs are not cheap; it could easily run $600. Only way to find out is to take it to Apple. Don't expect a quick and cheap repair.

    If the apple store quotes you an outrageous price, you could always buy the parts and fix it yourself, if you are tech savvy.

    Go to www.ifixit.com, choose the macbook type you have from the menu and find the disassembly guide.

    From there, you can figure out just what was under the spill area, and how many possible things you mucked up.

    Ignore iFixit guides. They won't help you here, and their prices for logic boards are more than the cost of a used macbook in working condition with the same specs.

    The upper left corner of the machine is where the logic board has a connector for the inverter board. Power goes to the inverter board from this portion of the logic board. It is logical(no pun intended) to draw the conclusion that the area of the spill, and the maleffect you are seeing, are directly related.

    Using a blow dryer is a terrible, terrible idea. You're just moving junk around the board. Getting rid of it is the idea here. We need something to lift it off, while the board is damp with a material that both cleans, and evaporates.

    With any luck, it'll work after you do what's posted below. When the screen comes on for a second then turns right off, it means the inverter board wires are swapped. If you cut the wire going from the inverter board to the LCD, and swap them around, that is what you'll see, which leads me to believe it's an inverter related problem.

    If it didn't work after the step listed below, I would try a new inverter with a new LCD. If that worked, I'd swap out the LCD, and the inverter for the old one one at a time to see which worked. If neither fixed the problem, I'd go around the board shorting resistors to each other until the LCD turned on. Once I find out what must short to turn it on, I would use one of those pencils(thanks dimitri! :D) that writes in electrically conductive material to create a permanent short, so the LCD always stays on.

    If the inverter and LCD panel are both known to be fine, and that issue occurs, where the backlight goes on for a second and then turns off, it is most likely to be fixed by the above method. This is only something I would try on a machine that wasn't a customer's, since if you short the wrong something bad is bound to happen. I would wait until it is unusable to try this.

    Then again, not having a backlight does render it semi-unusable. It is up to you. In the meantime while thinking that over, read what I have quoted below. I've posted this many times. I have had a 100% success rate with spill damaged macbooks using this method, but then again no one who has called me has tried to do it themself. Once I hear that someone has tried to fix their own machine, I typically hang up, since that means my life will be twice as miserable.

    Try it out. My method is less crude, but this uses household appliances & materials you either already have or can easily obtain/borrow.
