    Light Gun

    Thought I'd dust of my old antique games cosole that has a light gun with my large LCD TV.

    However the light gun doesn't work with the LCD TV, but did work with a big old fashioned CRT TV.

    Can someone here who understands the details of how TV's work explain why the light guns doesn't work on the LCD, and if there is any way of making it work?

    Should I put the light gun in the bin?

    No. Someone might call the police and you can get shot. If you want quick divorce then ask your wife to do it.

      Have you tried random tinkering with the sensor calibrator?

        Probably because the gun uses Cathode Ray Timing.

        This method relies on the nature of the cathode ray tube inside the video monitor. (CRTs were the only affordable TV monitors in the late 1980s and early 1990s, when this method was popularized.) The screen is drawn by a scanning electron beam that travels across the screen starting at the top until it hits the end, and then moves down to update the next line. This is done repeatedly until the entire screen is drawn, and appears instantaneous to the human eye as it is done very quickly.

        When the player pulls the trigger, the computer (often assisted by the display circuitry) times how long it takes the electron beam to excite the phosphor at the location at which the gun is pointed. It then calculates the targeted position based on the monitor's horizontal refresh rate (the fixed amount of time it takes the beam to get from the left to right side of the screen). Either the computer provides a time base for the horizontal refresh rate through the controller's connector , or the gun reads the composite video signal through a T-connector on the A/V cable. Once the computer knows where the gun is pointed, it can tell through collision detection if it coincides with the target or not.

        Display timing is useless with plasma, LCD, and DLP, which refresh all pixels at the same time.

        Don't chuck the gun in the bin, just by a cheap CRT telly to use with the console.

          Thanks. Clear, helpful, concise, accurate and polite.

            To check that he is right why not pull your 42 inch Plasma telly to bits and check that it isn't faulty. Remeber the order you took it to bits in though as you'll probably want to use it again in the future

            I preferred version 1!

              Have you tried turning it off and on?

                I hope you take out their 'oh so reasonable extended' warranty which covers the for 'accidental' damage

                  Buy a Wii and that Crossbow light gun with Link's (the Zelda elf) Crossbow challenge.
