A Step-By-Step Guide To Separating Your Monitor From Crt Tv

Removing the monitor from a CRT TV can be a dangerous task, and it is important to take safety precautions. CRT monitors contain large amounts of lead and phosphor, which can be harmful to the environment if not disposed of properly. Before beginning the removal process, ensure that you are wearing safety goggles and insulated gloves to protect yourself from potential hazards. Additionally, it is crucial to discharge the CRT monitor to release any remaining voltage. This can be done by connecting a wire to a ground source and touching it to the end of a screwdriver, which is then inserted under the suction cup on the side of the tube. Once the monitor has been safely discharged, you can proceed with removing the screws that hold the case together and sliding off the case.

Wear safety gear, including gloves and goggles

When removing the monitor from a CRT TV, it is important to wear safety gear, including gloves and goggles, to protect yourself from potential hazards. CRT TVs contain several hazardous components and toxic materials that require careful handling. Here are some reasons why wearing safety gear is crucial:

Protection from High Voltage: CRT TVs can retain high voltage even after being unplugged for extended periods. Wearing insulated gloves can protect you from lethal charges and reduce the risk of electric shock.

Eye Safety: Safety goggles or glasses are essential to prevent eye injuries or blindness in case of an implosion of the tube. The glass screen of a CRT TV is under significant pressure, and if it shatters, glass shards can cause severe eye damage.

Toxic Substances: CRT TVs contain toxic materials such as lead, phosphor, beryllium, and cadmium. These substances can be harmful if they come into contact with your skin or eyes. Gloves and goggles provide a barrier, reducing direct exposure to these toxic materials.

Sharp Objects and Glass: Disassembling a CRT TV may involve handling sharp objects and broken glass. Gloves can protect your hands from cuts and punctures, while goggles can shield your eyes from flying glass fragments.

X-ray Emissions: Some tubes within CRT TVs emit X-rays, which can be harmful to your health. Wearing safety gear, including a face shield or goggles, can provide additional protection from X-ray exposure.

It is important to prioritize your safety when working with CRT TVs. Always follow safety procedures, wear the appropriate gear, and handle hazardous components with care to minimize the risk of injury or exposure to toxic substances.

Remove screws holding the case together

Removing the screws that hold the case together is the first step in dismantling a CRT monitor. This process requires caution, as CRT monitors can be dangerous to take apart. High voltage may remain stored inside the tube even after being unplugged for several years, so it is important to take the necessary safety precautions.

To begin, make sure you have the right tools. You will need a pair of rubber gloves, two cutting pliers, a Phillips-head screwdriver, a flat-head screwdriver, and safety goggles. The types of fasteners used may vary, so it is important to have a variety of tools on hand.

Now, let's get started on removing those screws! First, locate the screws holding the back of the case on. These screws may be hidden behind small plastic doors, stickers, or in between seams. Be sure to also check for plastic tabs, which are usually located on the top, sides, or bottom of the CRT monitor. These tabs can be tricky to unhook, but they can be popped open with a little effort.

Once all the screws have been removed, you can carefully take off the cover. It is important to work slowly and carefully to avoid damaging any of the internal components. With the cover removed, you will have access to the inside of the CRT monitor and can begin the process of discharging the CRT tube and removing the circuit boards.

Remember to always put safety first when working with CRT monitors. By taking the necessary precautions, you can successfully remove the screws holding the case together and begin the process of dismantling the CRT monitor.

Slide the case off

Once you have removed all the fasteners, you can slide the case off. It is best to place the tube on its face at this stage, as it makes the disassembly process much easier. Since the CRT may still hold a lethal charge, it is recommended that you put on insulated gloves for the next steps and avoid touching high-voltage components.

It is important to note that taking apart a TV or monitor can be very dangerous. High voltage may remain stored inside the tube even after being unplugged for several years. Therefore, it is crucial to wear safety goggles and insulated gloves to prevent injury or death in case of mishandling.

Before sliding the case off, you should discharge the CRT. This can be done by connecting a wire to a ground source, such as a metal rod sticking out from the ground, and then connecting the other end of the wire to a flat-head screwdriver. Gently insert the flat-head screwdriver under the suction cup on the side of the tube until you hear a zap, indicating that the tube still contains a charge. Continue prying the connector until it is removed.

After discharging the tube, you can proceed to cut the ground wires from around the tube. You should also remove any springs attached to the wires, as they may be useful for later. Once all the wires have been cut, you can then safely slide the case off the CRT monitor.

Discharge the CRT

Discharging a CRT monitor is a critical step before working on a CRT-based display. The amount of voltage held by the CRT can be lethal and lead to possible death. Here is a step-by-step guide on how to discharge a CRT safely:

Wear Protective Gear:

Put on safety goggles and rubber gloves. It is also recommended to wear rubber-soled shoes to insulate yourself from the ground. Remove all jewellery, especially metal items like necklaces, rings, and watches, as these can create a path for electricity and increase the risk of electric shock.

Prepare the Tools:

You will need a screwdriver with an insulated handle, preferably rubber-coated, and a piece of wire. The wire should be thick and preferably one that you don't mind melting. Attach a clip or wrap one end of the wire around the screwdriver.

Unplug the Monitor:

Before proceeding, ensure the monitor is unplugged from the power source to prevent any further charge from building up. If possible, press and hold the power button for 30 seconds to 1 minute to discharge the monitor further. Modern "bleeder-based" CRTs may discharge sufficiently with this step, but a manual discharge is still necessary as the process with resistor-based tubes is silent, and you won't have a visual indication of completion.

Locate the Anode:

The anode is a wire covered by a suction cup, usually found under a big red cap. It is connected to a large red wire coming from the flyback. This wire carries a high voltage, so be cautious not to touch it directly.

Ground the Wire:

Find an unpainted portion of the metal frame of the monitor and connect one end of the wire to it. Ensure that the frame is large enough, as a small piece of metal may not provide an adequate ground.

Use the screwdriver to gently lift the suction cup and touch the metal conductor underneath. You should hear a loud pop or crack, and you may see a blue flash. This indicates that the CRT has been discharged. If you don't hear the sound or see the flash, repeat the process a couple of times to ensure the CRT is fully discharged.

Wait and Repeat:

After discharging, wait for about 30 minutes and repeat the process. This ensures that any remaining charge is released, making it safe to work on the CRT.

It is essential to follow these steps carefully to avoid the risk of electric shock or injury. If you are unsure or uncomfortable with the process, it is best to seek professional assistance.

Cut the ground wires

To cut the ground wires, you will need to separate the circuit board from the tube and the casing. This is a crucial step when dismantling a CRT monitor or television to ensure safety and allow for further disassembly.

First, put on insulated gloves for protection. The CRT may still hold a lethal charge, so this step is essential. Identify all the ground wires around the tube and carefully cut them using cutting pliers or wire cutters. You may also need to remove springs attached to the wires, which can be useful for later projects.

Cutting the ground wires will enable you to remove the main circuit board. Be cautious when handling the circuit board, as you will want to avoid damaging it so you can desolder the onboard components later. Once the main circuit board is removed, you can proceed to the next step of dismantling the CRT monitor or television.

It is important to note that CRT monitors and televisions contain hazardous materials such as lead and phosphor. Therefore, it is crucial to take appropriate safety measures and dispose of or recycle the parts properly to prevent environmental contamination.

Additionally, CRTs can hold a lethal charge even after being unplugged for an extended period. Before attempting to cut the ground wires, ensure that you have discharged the CRT by grounding the wire under the suction cup on the side of the tube. This step is crucial for your safety and should not be skipped or rushed.
