    You have to reverse the wiring on the yoke (the thing on the neck of the picture tube inside the set, with thick copper wires wrapped around it). Take a look at this webpage and it will give you some idea of what is involved. Be careful of this if you don't know what you're doing, there are high voltages inside the set. Make sure it's unplugged before attempting anything. You'll also need a soldering iron and solder.

    This page describes something similar to what you want to do, not exactly. It's just to give you an idea of what you have to do.

    Like roundabout said you have to reverse the wires on the yoke. There should be four wires: red & blue / green & yellow. Wires blue & red are for horizontal deflection and green & yellow are for vertical. I'm not sure if this is the same for all tvs but it's all i've seen. Don't know why you wanna do this for but i'm strangely interested as to what it would look like. Let us know how you go and if you can post a pic of the final screen image.

    oh man...I must advise against trying to make this work...I too was mesmerized by the "150in Projection TV" offer a couple of years ago...after much cutting of cardboard and using mirrors and turning the TV upside down (even going so far as to design a table that would hold the TV at the appropriate angle and level...) it doesn't work as it says it will!!!!

    Granted, it does project an "image" onto your wall (or screen or whatever you might be using), and the image is upside down. But I personally have never been able to acheive anything that was acceptable to me...

    I haven't worked on it in quite a while...maybe theres something new that I haven't looked at...but in my opinion, it doesn't work. Good luck though...and if you have success, please post again and let us (me) know.

    ye i too have tried the 'amazing 150in projection from any tv' scam, i knew it wouldn't work but curiosity got the better of me as usual. Granted i did get images to project on the wall in absolute pitch black darkness but it look really dull and crappy, not good enough for watching television let alone DVDs. Oh well look at it this way when you get old and your eyesight isn't as good as it used to be, you can always use that plastic lens thing to read the newspaper. Thats just my testimonial by the way, so good luck.

    Just a warning. Simply unplugging the TV is not enough -- lethal charges can be retained in the set for a very long time. The safe rule of thumb is to leave in unplugged for a couple of days before you touch anything.

    A bit extreme...

    I worked on TV's and around High Voltage most of my life. I've been zapped by the 35,000 v. live anode lead of TV's many times. Shocking, makes you jump up and down and curse, yes. Lethal, not likely - unless you stay in contact with it for more than a few seconds. Yes, there is a residual charge left on the anode lead after powering off and unplugging the unit, but even if you were to come in contact with it, it would only last a second. Certainly enough to get your attention, but enough to kill you? Hardly. The voltage is high, but the current is very low.

    That said, it's not a good idea to mess around inside of a TV when it's on, unless you know what you're doing.

    Ok, I'll admit to hyping up the drama a little. The odds of residual current killing you are pretty slim -- but it can happen, and so a warning seemed in order.
