Safe Dismantling of Your Hitachi Projection TV
If you're looking to discard your Hitachi projection TV and are concerned about the safety of dismantling it, you've come to the right place. This guide will provide you with step-by-step instructions, safety precautions, and tips to ensure a safe dismantling process.
Understanding Your TV
Projection TVs, especially older models like those from Hitachi, typically use CRT (Cathode Ray Tube) technology. Here are some critical components you should be aware of:
- CRT Tubes: These contain high-voltage components and can retain an electrical charge even after being unplugged. They are also fragile and can shatter if mishandled.
- Liquid Gels: Used to cool the CRT tubes, these gels can leak if the casing is damaged, though harmful exposure is rare.
- Glass Components: The TV has several glass parts that can break easily and pose a risk of injury.
Safety Precautions
Before you begin the disassembly process, take the following precautions:
- Unplug the TV: Ensure the TV is completely unplugged from the wall socket.
- Cool Down: Allow the TV to cool for at least one hour before starting the disassembly.
- Wear Protective Gear: Use safety goggles and gloves to protect yourself from glass shards and other potential hazards.

To dismantle your Hitachi projection TV, you’ll need some standard tools, and it’s important to handle everything with care, especially the fragile components. Start by disconnecting all external devices and unplugging the TV from the wall. Allow it to cool down for at least an hour before you begin.
Once you’re ready, you can typically start by removing the front board or the back of the TV. Carefully pull the speaker grille forward to detach it from the cabinet. Next, use a Phillips screwdriver to remove the screws securing the front board and take it off. After that, remove the control panel by unscrewing it as well.
When you get to the screen assembly, take out the screws at the bottom and lift it up while pulling it forward. Then, move to the back of the TV and remove the screws holding the back board in place. You can also take out the board shelf by unscrewing it. Finally, carefully remove the light box assembly by unscrewing it and pulling it through the back of the cabinet.
Be particularly cautious with the CRT tubes, as they can hold a charge and deliver a shock if not properly discharged. Additionally, if the tubes break, the glass can be dangerous, and the phosphor coating on some screens can be toxic. So, make sure to handle these components with extra care.
With these steps, you should be able to dismantle your TV safely. If you have any more questions or need further assistance, feel free to ask.
