  I do not think it will work because my KV25XBR has a 34 pin RGB imput and the service manual shows that RGB requires separate red green and blue imputs *plus* separate horizontal sync and vertical sync, for a total of five cables! I think composite has the H-sync and V-sync mixed with the red green and blue, and S-VHS doesn't separate the three colors from each other at all!

  In some cases it may be possible to find a true RGB + H-sync + V-sync signal inside the player.

  Good luck

    Whoops! I may be wrong here but if the blanking signal is not necessary, then 34 pin RGB may be compatible as it has composite sync input on pin 30!

    Sorry

    Here are the pin assignments

    8 - Red Gnd
    9 - Green Gnd
    10 - Blue Gnd
    12 - Blanking Gnd
    13 - H-sync Gnd
    15 - V-sync Gnd
    25 - Red
    26 - Green
    27 - Blue
    29 - Blanking imput
    30 - H. sync or composite sync
    31 - V. sync

  I see no reason why your 34 pin input could not be used. Try Radio Shack for an adaptor. Otherwise, if you know the pin connections it would be relatively simple to make an adaptor.

  However, whether or not you will see an improvement is questionable. It depends a lot on the quality of circuitry, the age & size of the tube etc. If it has provision for component input then I guess the quality circuitry is there. Component input, particularly on enhanced DVDs can be stunning, and shows up brilliantly on big screens. However not all DVDs are high quality :-( so it can be chasing after moonbeams.

  My suggestion is to give it a go as the cost will be minimal. Do not mess about with S-video if you have component capability, and do not waste dollars on expensive cabling.

  Good luck

  John
