If you couldn't just wipe off the liquid, there are two possible places it could be hiding: If you have an aftermarket screen protector, some might've gotten under it. Try with your fingernail to lift the edge of the screen surface. If that doesn't do the trick, it's probably between the touchscreen digitizer and the display panel. Opening the screen is easy. You'll need a #1 Phillips screwdriver and about twenty minutes. Identify the hinge cover, a single piece of formed sheet metal that runs along the top of the keyboard above the F-keys, and curves around the hinges to the back of the machine. Start with the laptop closed, standing nose-down so the handle is in the air. Remove the two screws securing the hinge cover to the chassis next to the handle. Then set the laptop down in its normal orientation, open the display 180 degrees, and remove the other three screws from the hinge cover. The hinge cover should now lift free. Set it aside. Now, remove the ten screws around the perimeter of the screen. You'll need to pry out the rubber bumpers to get at two of them. Once all ten are out, raise the screen to the 90-degree position and gently separate the cover from the frame. At this point, the back of the display panel should be visible, along with the flex cable that leads into the main cabinet, the backlight inverter, the touchscreen control board, and the wireless antenna, if equipped. Identify the connector where the clear four-conductor flex cable from the touchscreen meets the control board. Gently pull the beige latch lever away from the connector and remove the flex cable. Do this with the other flex cable connectors, too. Now you should be able to separate the display panel itself from the frame. I believe it's just held in by rubber bumpers, though there might be a few screws too. (It's been years since I had my display apart.) Once you have the display out, any liquid between it and the digitizer surface (which is bonded to the frame/bezel) should be easy to remove. Installation is the reverse of removal. Observe static precautions, and work in the most dust-free environment possible. Any speck trapped between the digitizer and display during reassembly will drive you nuts!

I have had some luck with just letting things dry out for instance dropped cell phone in water completly submerged I shook what I could out of it sat it on my dashboard in van (after taking battery out) waited about a week cut it on and it worked like a champ Electronics are funny things This is something you could try depending on how fast you need it back you dont have to put it on dash just somewhere near heater may work or may not but worth a shot has worked for me in the past.

I didn?t understand exactly what was going on with your LCD monitor, however, if the Windex leaked into the monitor and it no longer works then the answer is probably but depending on what is damaged it may not be economical to do so. If the Windex just leaked into the laptop and it still works then you?ve been luckily. In either case the thing to do is disconnect it from the A/C power source and remove the battery to prevent further damage. You or a repair shop needs to disassemble the appropriate components and remove any remaining liquid immediately.

    The problem with letting things dry out is that they deposit whatever material they had in suspension. Clean Windex by itself isn't too bad but the problem with letting things dry naturally is that you never really know if its all dry and Windex, water and soda are excellent conductors.

    At the very least you need to put the device in a hot box of some sort where the temperature is sure to warm up the device and evaporate the liquid.

I have several large water spots on the lower right corner of the tv from overspray with windex. Can this be fixed?

Not a good idea to clean tv with windex. Try wet towel dipped in mild soap solution. Make sure all water has been removed and towel is only wet. When tv off, try removing the spots. Turn tv on only after tv dry.

How do we remove erasable white board marker from the apollo screen?

With Windex, just use a wet rag afterward to make sure the ammonia is not left behind. If the screen is stained that is a different issue as you will have to use a cleaner that actually removes some of the screen, but doesn't eat through it entirely.

GPS touch screen sprayed with Windex; doesn't work.

After reading sharcnet's reply yesterday that putting the unit in the freezer was absolutely the wrong solution, I was very panicked! However, once the unit thawed out it worked fine. We tried the freezer because we've used that tip before to "freeze-dry" cell phones that got wet. Luckily the LCD was not damaged & everything is working fine now. And my husband knows not to spray Windex on any electronic screen!

Wet screen

You will need to take out the screen from the front of the TV set. Then the screen will be taped together, as it is in two pieces. Clean the screens very carefully and do not forget what way you took them apart. It will make a differance as they are simply not plastic, they are each a special lens. Good Luck
