How To Check If Logic Board Is Water Damaged: 6 Signs

When your device has taken a swim, you would probably ask how to check if logic board is water damaged. This article will guide you on what to do if you happen to be in this situation. 

Before anything else, the following lists the telltale signs that your device’s logic board is water damaged:

  • Battery is not charging.
  • Phone’s system does not recognize the battery.
  • Phone’s display does not show backlight or image.
  • Phone randomly crashes. 
  • USB ports are not functioning.
  • Phone does not turn on.

 

What To Do If Logic Board Is Water Damaged

The first step in any situation including the absorption or splashing of an electronic equipment in any liquid is to turn off all power sources as soon as it is safe to do so.

Here are the tips you must keep in mind:

  1. First and foremost, give heed to your personal safety! When detaching any equipment from household power or any other origin, proceed with caution. 

Protect yourself from any possible shock hazard if you are standing in water or your clothes are wet before attempting to retrieve a submerged or drenched electrical equipment.

  1. Find a safe technique to disconnect the electrical gadget if it is still underwater and attached to an outside power source. Locate a circuit breaker or switch for that source of power and turn it off if possible. 

If you decide to disconnect a plug or power adapter from an outlet that has not been turned off, do so with caution.

  1. Recovering a drowned or drenched electronic device with a battery comes with its own set of risks. A shorted battery might cause a fire or a chemical reaction. 

Never touch the electronic gadget if you notice or feel heat, smoke, steam, bubbling, bulging, or melting.

  • If the device is still in use, turn it off.
  • Rotate and jiggle the device to see if any liquid has leaked out.
  • Take the battery if at all possible.
  • Disassemble the device if feasible to empty any remaining liquid and begin cleaning the inside components. This is especially true for acidic beverages like fruit juice and alkaline liquids like laundry water.

 

How To Clean Logic Boards

If you decide to clean your water damaged logic boards yourself, here are the things you need to bear in mind:

Step #1. Disassemble your gadget completely by removing all wires, opening all ports, and removing shields to gain access beneath them. Drench the logic board entirely in a suitable sized container filled with isopropyl alcohol to expel any remaining liquid around or under any components. 

Use a concentration of 90 percent or greater, which can be obtained from a pharmacy or drugstore. As an alternative to distilled or deionized water, you can use purified, but it will take longer to dry. 

Ketone, acetone, and naphtha are all solvents to shun. If you want to know the right chemicals, read through this article on what chemical works for water damaged circuit boards.

Step #2. Wipe the logic board with a toothbrush, small paint brush, or other soft brush to remove any debris or deposits from the irritating liquid. Cleaning the logic board should be done with caution to avoid harming or knocking out components. 

To prevent corrosion of the contact surfaces of ribbon cables, pay special attention to the connectors and ends. If you have an ultrasonic cleaner, you may clean the exposed sections of the board more completely. 

Furthermore, filth and rust will be removed from locations where a toothbrush cannot reach.

Step #3. Once you’re certain that the logic board is fresh and free of corrosion, dry it with a hairdryer set to the cold setting. Instead, you can slowly heat the logic board and dry out the cleaning fluid by placing it under a desk lamp.

Step #4. Inspect the cable ends and connectors for indications of corrosion or debris after the parts are dry.

Step #5. Replace the battery in your smartphone with a new one or one that you know is in good operating order. If your gadget has been submerged, you will almost certainly require a new battery. 

Absorption is not good for lithium and other kinds of rechargeable batteries. Again, any popping, bulging, melting, or discoloration on the battery means it’s toast. 

Only discard it at a battery recycling center. Do not leave it anywhere else for safety purposes.

Step #6. After you’ve constructed your equipment, the true process of assessing the damage begins. Look for what’s working and replace pieces in a systematic, not all-at-once manner. 

In a smaller electronic gadget, the battery, LCD, and logic board are most likely to fail in that order. Because water damage is so common, adjusters must know what to look for when dealing with claims involving water-damaged electrically powered goods. 

Whether or not electronic items can be restored after a water damage incident depends on the kind of equipment, the origin of the water, and the amount of the damage.  To help adjusters deal with this commonly reported risk, it is best to go over the different sorts of water damage, what to look for when dealing with these claims, and how to get the insured back to pre-loss state.
