Liquid Spills – Dead on Arrival or Repairable Problem?

Tuesday, December 14th, 2010

Liquid spills are amongst the most damaging issues you can have with any electronic.  After all, water (and therefore most other liquids) conduct electricity very well, bridging components together that very much don’t want to be bridged.

Of course, the easiest way to avoid this problem is to simply keep liquids away from our computers, especially laptops that are more easily damaged.  Lets face it though, we all grow a little lazy after a while when it comes to keeping liquids at a great distance, myself included, and that glass of water, or can of soda slowly creeps its way closer and closer to our beloved laptop.

You’re in luck, though, as most spill situations are solvable.  However, a few initial steps need to happen to lessen the chance of permanent damage:

  1. Force shut down the computer by holding the power button until it turns off.
  2. If the system is a laptop, remove the battery so that power no longer can go to the system at all
  3. Bring the system into a repair shop that is comfortable with liquid spill cleanups.

In most situations, the liquid itself does not cause any damage.  However, especially with liquids that have sugars in them like juice or soda, the sugar can crystallize and create corrosion on the system, which can cause conductive bridges between the small components on the boards inside the computer, which can then cause a short, or can burn components when the power is restored.

If the system is properly cleaned before this is able to happen, then you can save your system from what would seem to be certain doom.  If you cannot, most of the time the damage to the system board is unrepairable (or at least not within a reasonable budget to repair) and would result in a need to replace a very expensive component.  Upon reaching this point, you can have your hard drive removed to recover data, and move into a new system.

Laptop Screen Issues

Thursday, October 28th, 2010

I’m sure we’ve all seen atleast one instance of a laptop screen issue, whether it be cracked, no longer lighting up, or have a glitchy image that’s solved only by physically moving the screen. Of course, fixing these problems would be less daunting if they could all be solved by replacing the LCD. But what happens when you replace the LCD and the same problem is still happening?

There are typically four main components that help to display video on your laptop. The motherboards video output, the LCD ribbon cable (attaches the LCD to the motherboard), the inverter board (inverts DC power to AC power), and the LCD itself.

Here are a list of some common problems that can be associated to each of these components. Keep in mind, the same issue can be caused by different components, and the only way to test these is to work with some known working components.

Motherboard: Artifacted images (can be duplicated by plugging in an external monitor), no display, no backlight, wrong colors in the screen, shifted image, fuzzy image. — Some of these issues can be resolved by simply updating video drivers.

LCD Ribbon Cable: Distorted image ( can be partially remedied by moving the screen around), flashing connection, no backlight.

Inverter Board: No backlight, red hue in image.

LCD Display: No display, no backlight, red hue in image, flashing connection, distorted image, shifted screen.

Use some of these guidelines to help discover the source of your issue. Of course, the easiest way to determine the source of display issues would be to bring your system in to ITZ Solved for a free diagnostic.
