My lg vx110000 touch screen stopped working after i sprayed windex on a cloth and cleaned the touch screen.

How to Clean an LCD Screen
So, first of all, let's decide what we don't use to clean it:
Anything containing bleach or ammonia, such as Windex. That will react with the plastic and make the plastic screen become cloudy and discolored.
Anything sharp, pointy or abrasive.
Your easiest choice is one of those LCD cleaning solutions they sell in places where they sell computers. But they're expensive, and why bother when you can make your own solution for next to nothing?

What you'll need:
Distilled water (available at your supermarket; tap water leaves streaks and minerals).
White vinegar (you may substitute isopropyl alcohol; either way, make sure these substances are diluted before they come near your screen).
A clean, soft cloth (never use any kind of paper product).
A spray bottle.

Directions:
In the spray bottle, mix the distilled water and alcohol/vinegar, in a 1:1 ratio.
Turn off the LCD display.
Spray the mixture onto the cloth, never directly onto the screen.
Wipe gently - oh, so gently - from top to bottom. Do it horizontally, too, if you think that leaves a cleaner result.
Let the screen dry before turning it back on.

Hands Off!
Fingers leave dirt and oil smudges that must be cleaned off. Also, every time you touch the screen you risk doing damage to those tiny creatures inside that hold the colored flashlights. Keep your fingers to yourself.

Proper cleaning of a Touchscreen

1. Step 1 Turn off both the computer and touch screen. This way, you can see everything that needs to be cleaned. Some touch screen applications has a cleaning mode which turns off the screen for the specific purpose of cleaning. However, the monitor's brightness can make you miss some areas.
   
2. Step 2 Wet a soft, lint-free or microfiber cloth with distilled water. Wring out as much water as you can. Make sure the cloth is damp but not wet. Wipe the screen in a gentle motion to remove dust, oil, or fingerprint smudges off.
   
3. Step 3 Another option is to use a screen cleaner kit that includes antistatic wipes. You can buy this at various electronic or online stores. Spray a little solution on a wipe then rub it gently across the screen.
   
4. Step 4 Finish cleaning the touch screen with a dry lint-free cloth to wipe any excess moisture, then turn it back on.

When I first got mine, I used Windex and a microfiber cloth to clean it.

Now, I use Phillips Screen Cleaning Gel. It does a better job and doesn't leave streaks like the Windex did at times.

Whatever you decide to use, the best thing to do is spray the solution on the microfiber cloth instead of directly on the screen.

Using a microfiber cloth will ensure you're not inadvertently scratching your screen.

ok you need to take out the inks then remove the print head it just comes out once the inks are taken out, get some windex and clean the bottom off the print head with a fine lint free cloth spray the windex on the rag then clean the print head, also if its really bad spray windex into the where the inks also sit give it a good squirt let it sits for a few minutes then wipe it out, make sure you DONOT touch the gold bits on the printhead. refit to machine do a head clean on the driver should work fine.

Take a clean cloth and spray some windex on the cloth and then wipe down the screen and it should come nice and clean. Never spray it directly on the screen cause if the liquid goes down inside of the screen then it could damage it.

Use any lintless cloth. Spray any clener you use on the cloth, not the screen. I often just spray a little Windex (or store equivalent) onto a terrycloth rag and use that.

Please do not use Windex. Use Anti-Static Monitor Wipes for LCD screens. Using Windex or other cleaning solutions like it will cause streaks on your screen. Damp cloths have the same effect as Windex.
