Are you still in possession of an old and unsafe CRT television and considering an upgrade? Were you aware that you have the option to dismantle it and sell certain components such as circuit boards, copper, and metal parts?
In my view, it’s a worthwhile suggestion since outdated televisions are generally difficult to sell. So why not make the most of it? However, exercise caution as old televisions often feature a CRT (Cathode-Ray Tube).
What is a CRT in TV?
A cathode-ray tube (CRT) is a vacuum tube that houses one or more electron guns, used to manipulate electron beams and display images on a phosphorescent screen.
Commonly known as a TV tube or picture tube, it contains hazardous substances, making it unsafe for disposal by regular means. Simply discarding the CRT tube is not an option. You may find yourself wondering, “Where can I dispose of it safely? I can’t throw it outside, and keeping it at home is not feasible.”
The solution lies in locating a specialized company that accepts and recycles these CRT tubes. By doing so, you can ensure both your own well-being and contribute to environmental preservation by properly disposing of these tubes.
However, it’s crucial to note that CRT tubes can retain high voltage for extended periods, posing potential dangers.
What You Need
Prior to commencing the entire procedure, it is important to ensure that you have the following items at your disposal:
- Needle nose pliers
- Side-Cutting Pliers
- Insulated Screwdrivers
- Alligator clips
How to break your TV Tube Safely
Note: You are doing this at your own risk. We’ll not be held responsible for any damage.
1. Open the Cover of the Television
To begin, your first task is to cautiously unscrew all the screws securing the cover of the television. Ensure that you handle this process delicately, avoiding excessive force, as exerting too much pressure could lead to damaging the picture tube.
2. Discharge the Monitor
Keep in mind that the Anode Cap is responsible for transmitting high voltage. Consequently, discharging a monitor can pose a potential danger. Follow these simple procedures to stay safe.
Here are some safety tips to follow:
- Stay aware of your surroundings, including any loose cables or objects that may cause tripping hazards.
- Prior to beginning any procedures, ensure that the TV is completely unplugged from the power source.
- Wear protective gloves to safeguard your hands during the process.
- It is recommended to wear a safety mask to prevent inhalation of any potential dust or debris.
- Make sure to switch off the TV and leave it powered down for at least 2 days before initiating any procedure.
- Avoid direct contact with any TV components, especially the Anode Cap and Electron gun, using bare hands.
- Utilize only an insulated screwdriver to perform any necessary tasks, ensuring electrical safety.
To carry out this procedure, you will require an insulated screwdriver and alligator clips. Begin by attaching one alligator clip to the screwdriver. Hold the free end of the alligator clip (not attached to the screwdriver) and connect it to the metal casing.
Next, gently insert the screwdriver into the anode cap, aiming to make contact with the metal inside the anode clip until you hear a clicking sound. Allow 2 to 3 minutes to pass, then repeat this step 2 or 3 more times to ensure safety precautions.
Once you have taken these safety measures, cautiously grip the rubber of the Anode cap with your hand and carefully remove it.
3. Cut the Wires
Next, you need to use the Needle nose plier to cut the wires in the TV. Now, you can start making money from the CRT tube. There is money to be made from selling the coil and copper.
4. Remove the Motherboard
Finally, you need to remove the motherboard. Apply caution. The motherboard is the small circuit board where you can see the speakers, buttons, etc. Proceed to remove all the big and small components using a flathead screwdriver. While tampering with the motherboard, remember to wear a glove.
5. Save or Sell The Parts
Whatever you want to do with the parts you removed is totally up to you. You can decide to save the parts or sell them—your call.
As mentioned previously, it is important to handle the disposal of old CRT TV tubes responsibly due to their toxic nature, which can be harmful to the environment. It is strongly advised not to simply discard the Cathode-Ray tube. Instead, it is recommended to seek out a reputable waste management company that can properly handle and recycle the CRT tube, ensuring the protection of the environment.
