Taking apart a TV or a monitor may sound easy, but they can be very dangerous if you are not careful...
This instructable will be your guide of taking apart a TV or a monitor.
Taking apart the TV or monitor can be very dangerous. High voltage presents inside the CRT - even when the power is off! And the CRT is fragile. You could get seriously injured or die. I am NOT responsible what ever happens to you if you take apart the TV or monitor!

Step 1: Tools...
What I used are:
- Screwdrivers in various types and sizes
- Some types of pliers
- A wire cutter
- A safety goggles
Step 2: Take the Cover Off
Take the back cover off the TV or monitor. The screws can be difficult to find, but take your time...
Step 3: The Dangerous Part...
Now, this is the dangerous part, discharging the CRT...
Why should you do this? Because the CRT acts like a high voltage capacitor and it can hold a lethal charge. The charge stored in the CRT can last a very long time, usually a few months, sometimes for a few years...
So it is important to safely discharge the CRT before you do anything else - otherwise you might end up in the grave...
To discharge the CRT:
Connect one alligator connector clip to a flat-head screwdriver, and the other clip to another any screwdriver.
Push one screwdriver into the earth ground and take the other flat-head screwdriver and gently put the end under the suction-like cap. Keep pushing it in until you here a loud (or faint) "SNAP", the CRT is discharged, but push in the screw driver until you feel a little bump, the screwdriver had touched the metal clips Now the CRT is completely discharged.
Now, simply cut the HV wire off near the suction-like cap.
I took the suction-like cap off completely because I know how to do it. Taking the suction-like cap off the CRT can be tricky and dangerous.
Step 4: Cut Up the Wires
Now the CRT is discharged, cut all the wire that are connected to the CRT. So we can take the electronics out.
Step 5: And the Screws...
And hunt down all the hidden screws and take them off the circuit board...
Step 6: Put the Cover Back On...
One last thing to do... Put the back cover back on the TV or monitor to make it safe from an implosion.
And can you do me a favor? Please take the CRT to a recycle facility. Please don't dump the CRT to the landfill. Because of this, the phosphor and other chemicals that make the CRT screen glow is extremely toxic and it is very harmful for the environment, so can you take it to a recycle facility?
Step 7: And You Are Done!
And you are done!
There are the instructions on how to take apart a TV or monitor!
The main reason why I wanted to take apart a TV or monitor is I am after one part: The flyback transformer. You can make many great high voltage projects with the flybacks.

And most of the other parts inside the TV or a monitor can be quite useful too.
