Fixing a loose cable bus

If your electric keyboard is under warranty, it's best to have it serviced by a professional to avoid voiding the warranty. If it's an older model or out of warranty, you can try fixing it yourself.

A common issue with electric keyboards is that a cable bus can come loose due to aggressive playing, moving the keyboard, or even the vibrations from the keyboard itself. If some or all of your keys aren't working, this is probably the first thing to check.

  • Unplug the keyboard.
  • Unscrew the underside of the keyboard. If it is a console-style keyboard, you may need to unscrew the top board or back piece instead.
  • Gently lift off the top of the keyboard and lean it back.
  • You should see two cables running from under the keys to the control panel. Ensure these cables are firmly attached.
  • If the problem persists, you may need to unscrew the unit holding the keys on the inside of the keyboard.
  • Lift up the entire rack of keys. You will see the other ends of the cables on the underside of the keys. Ensure these cables are also firmly attached.

If you need to take further action, it is recommended to consult a professional or seek advice from a specialist forum.

Cleaning the keyboard

Before cleaning your electric keyboard, make sure to unplug it from the power source. It is important to be cautious when cleaning your keyboard, as using the wrong cleaning product can cause damage to the mechanisms of the keys, altering their functionality.

Firstly, give the keyboard a light dusting with a feather duster or a very soft clean paintbrush. This will help to brush off larger bits of dust and prevent them from becoming lodged in the keys.

Next, use a soft microfiber cloth to wipe down the keyboard. If necessary, you can dampen the cloth very lightly with lukewarm water or a mixture of soap liquid and warm water. Make sure to wring out the cloth thoroughly before wiping down the keyboard, ensuring that no water drips onto the keys.

If your keyboard is particularly dirty or sticky, you may need to use multiple cloths. Take a second microfiber cloth, dampen it with lukewarm water, and wring it out so that it is not dripping. Use this cloth to wipe down the keys in a "toward-the-player" motion. Then, take a third, dry microfiber cloth and wipe down the keys again in the same motion until they are completely dry.

Some people recommend using a small amount of Pledge Antibacterial or another safe cleaning spray on the microfiber cloth to help remove stubborn dirt and grime. However, it is important to avoid using any liquid or spray cleaners that contain high levels of bleach, alcohol, or other harsh substances, as these can damage the keyboard.

In addition to cleaning the keys, you may also want to clean the inside of the keyboard to remove any dirt or dust that has accumulated there. To do this, carefully unscrew the underside of the keyboard and lift off the top. Look for any signs of dirt or dust, especially around the sensors, as this can interfere with the keyboard's functionality. Use a microfiber cloth or a computer air duster to gently remove any dirt or dust from the inside of the keyboard. Make sure that all cables are firmly attached before replacing the screws and testing the keyboard.

Replacing individual keys

Before attempting any repairs, it's important to check if your keyboard is still under warranty. If it is, it's best to have it serviced by an approved professional so you don't void the warranty. If your keyboard is older, out of warranty, or you're unable to get it repaired, you can try fixing it yourself.

First, check that the keyboard base is intact. Ensure that the rubber nub in the centre is still present, along with the small metal or plastic hooks that hold the key. If the hooks are bent, you can use needle-nose pliers to gently pry them back into place.

Next, inspect the back of the key for any damage. Turn the key over to check if the part that latches onto the keyboard is intact. You should see a small plastic piece that attaches to the keyboard base. If this latch is missing, you may need a replacement key, which can be purchased online.

Now, it's time to loosen and remove the key. Make sure your keyboard is unplugged before proceeding. Gently pry all four corners of the key with a tool like a spudger to loosen it. Carefully lift the key until it pops loose. If it's difficult to remove, try gently prying all four corners again.

Once the key is removed, use tweezers to take out any contaminants that were preventing the key from functioning properly. Be careful not to grab the actual button, as breaking it could permanently damage your keyboard.

Finally, it's time to install the new key. If you're replacing the entire key, ensure that it's intact and not damaged. Align the key with the base and plunger, making sure it's in line with the plunger. Gently press the key back into place, waiting for a click. Don't press too hard to avoid damaging the plunger.

If you're only replacing the key cap, simply push the new cap into the open hole until you hear a popping sound. Ensure that the keys click in easily; if not, try realigning the key.

After replacing the key(s), plug in your keyboard and test it out to ensure that it's functioning properly.

Fixing sticky keys

If your electric keyboard is under warranty, it is recommended to have it serviced by a professional to avoid voiding the warranty. If your keyboard is older, out of warranty, or you cannot get it repaired, there are some things you can try to fix sticky keys yourself.

Sticky keys can be caused by dirt, dust, debris, or dried-up lubrication getting stuck in the keyboard mechanism. To fix this, you will need to clean the affected keys and their mechanisms. Before you begin, it is recommended to take a photo of the keyboard to remember the key positions. You will then need to remove the sticky keys. This can be done safely using a keycap puller, which allows you to access the underlying mechanism without causing any damage. Once the affected keys have been removed, you can use a cleaning solution such as isopropyl alcohol or rubbing alcohol to dissolve grease, grime, and dust without leaving residue behind. You can then apply a small quantity of a suitable lubricant, such as a silicone-based or Teflon lubricant, to the mechanism to facilitate smooth key movement. Avoid applying lubricant directly to the keycap.

If there are large objects stuck under the keys, such as residue, you can use tweezers or a toothpick to remove them. You can also use compressed air to prevent future sticking. Once the keys and mechanisms are clean, you can replace the keys and screws, and test the keyboard to see if the problem has been solved.

If your keyboard keys are still sticking, particularly if it is an older mechanical keyboard, you may need to take it in for professional repairs.

Checking the warranty

If your electric keyboard is under warranty, it's best to have it serviced by an approved professional. This way, you don't run the risk of voiding the warranty if the problem is something you can't fix. Your local music store should be able to help you find a repair person who works with your keyboard's manufacturer.

Different manufacturers have different warranty periods. For example, WASD keyboards carry a 2-year limited warranty, which covers manufacturer mechanical or electrical defects, parts, labour, and one-way shipping. The limited warranty does not cover physical or elemental damage caused by anything that is not due to a manufacturer defect, such as beverage spills, karate chops, or bowling ball drops.

If your keyboard is older, out of warranty, or there isn't a way to get it repaired, you may have to attempt to fix it yourself. However, this may void any remaining warranty, so it's important to check the terms of your warranty before attempting any repairs.

Some manufacturers may refuse to cover repairs or replacements under warranty. In such cases, you may have no option but to try and fix the keyboard yourself.

Frequently asked questions

The keys may not be working due to several reasons, including dirt or debris stuck between the keys, a faulty motherboard, or accidental damage caused by crumbs or liquid.

Try pressing down on the stuck key and the keys adjacent to it. If that doesn't work, use a flathead screwdriver to gently insert between the stuck keys and twist slightly to release them.

Unplug the keyboard and remove any batteries. Turn it upside down and gently shake it to remove any crumbs or debris. You can also blow canned air between the keys to remove dust and dirt. Use a clean cloth to wipe down the keyboard, and if there are any stains or spills, use a cloth with warm water or rubbing alcohol to clean the affected area.

Unplug the keyboard and unscrew the underside. Gently lift off the top and check if the cables going from under the keys to the control panel are firmly attached. If they are not, simply plug them back in and screw the keyboard back together.

If cleaning the keys does not fix the issue, you may need to replace the individual key or switch. If the problem persists, consider taking your keyboard to a professional for repair or replacement.
