    There are ways of doing this, but a TV screen won't give a good oscilloscope. Traditional oscilloscopes use electrostatic deflection while TV image tubes use magnetic deflection. Magnetic deflection is more powerful and indicated for large sized tubes. The vantage of electrostatic deflection is that it allows much more fast changes and more control over the cathodic ray. There is another factor you have to take into account, and that is the persistance. Oscilloscope tubes have longer persistance, desirable for that particular function.

    What does "profissional" mean? Does it mean "in favor of fishing?"

    I believe it is similar to "antifusional".

    A television converted to an O-scope will at best give you a 20KHz sweep.

    There are lots of other options out there. Since you already have a computer, and it probably has a sound card - you have most of what you need for a low-cost O-scope.

    You can download Winscope from this page; it's the software that uses your sound card as an input device for a simulated oscilloscope.

    Have a look at this page for more ideas:

    All you professional engineers who get excited at the thought of converting a 42" LCD Television to an oscilliscope please raise your hands. I'm detecting a distinct lack of enthusiasm for this concept. If you want an oscilliscope then get an oscilliscope.

    LCD? In my opinion, doing that is a waste of money and the oscilloscope it may give won't be that great.

    Nevertheless, I'm looking forward to see that if you have the funds.

    Yes it is a complete waste of time with any television monitor, that was kind of the point I was trying to make.
