Wear protective gloves, and clean the area with a damp rag. If you accidentally break a CCFL bulb:ĭo not touch any glass shards or spilled liquids with your bare hands. If broken, they may leak small amounts of mercury, which is very toxic. CCFLs look like long, tube-shaped fluorescent lights, usually placed behind or to the sides of the display. Use extra caution with CCFL-backlit displays. Some pre-2010 flat screen displays used cold cathode fluorescent lamps (CCFLs) containing mercury. The power supply usually looks like a circuit board with a series of cylindrical capacitors that look roughly like battery cells.Īvoid touching or prying near the capacitor leads unless you have verified that they are fully discharged. Unplug the TV from the power outlet before you begin work. This should go without saying for all electronic devices, but flatscreen displays contain power supply boards with large capacitors that can be particularly dangerous when charged.īefore touching any other internal components, disconnect the power supply from the main board. However, there are a few potential hazards to be aware of if you've chosen one of these displays for your project.

Modern flat screen displays are much safer to service than older, CRT-type TVs and monitors. If circuit boards or other electronic components are beyond repair, recycle them responsibly. Put them in a sealed container and take them to your local household hazardous waste disposal facility. Protect the environment. Don’t throw lead solder, nor sponges contaminated with lead solder, into the trash. Keep a fire extinguisher nearby, and make sure you know how to use it. Never leave a hot soldering iron unattended. Set the soldering iron down only on the iron stand. Keep your workspace tidy, and clear it of any flammable objects before you begin. Solder only on heat-resistant surfaces and materials. Protect against heat, fire, and other hazards. Protect your eyes. Solder can “pop” and “spit” unexpectedly, so wear safety glasses at all times. Wash your hands after finishing your work. (If it's hot enough to melt solder, it's more than hot enough to burn you.) Don't use your bare hands.ĭon't touch the tip of the iron. Hold wires and solder with tweezers, or wear heavy gloves. Keep your head to the side of your work, rather than directly above.

At the very least they will irritate your lungs if inhaled, and may aggravate certain medical conditions such as asthma. Protect your lungs. Solder fumes can be toxic. Soldering can be both safe and fun, provided a few basic safety guidelines are followed. Some repairs require soldering, which may be intimidating for first-time fixers.
