Okay, I've found more information about my CRT Projector. It's in a storage unit right now, and I need another person to help me carry it to the car and then into the house, but I got some information now. I have a "Barco Data PC" projector. It has no numbers anywhere on it, except for a very tiny small plate under the RGB inputs on the back that says the model number "CH-43". (I think). I also have the RCVDS 400 switch. I've only been able to find one image of my setup online, and here it is: http://www.avforum.no/pp-classifieds/showproduct.php?product=59. I'm missing the cable that connects the switchbox to the projector, and I don't have any kind of handheld remote. Just the switchbox. I have been unable to find any information, be it manuals, setup instructions, or even MENTION of this model on any of the projector sites Google has led me to. I have no idea the resolutions it's capable of or even how to use it. Basically, my problem is this: I turn the projector on, I hook up a composite video or VGA input, and nothing happens. The projector makes all the right noises (fans, high pitched tube noise, etc), but nothing is ever displayed from the tubes. Not even a test pattern. Changing the input resolution causes a change in the high pitched noise, as if it were syncing to a new signal, but no image is ever displayed. It doesn't make any noises like it's broken or trying to turn the tubes on... they just never come on. So I'm now wondering if I have to have this RCVDS hooked up in order for the thing to operate. I have no manuals or anything, and thus I don't know if this is operating by design or if I'm missing something or if it's just broken. I picked up the thing at a State Surplus auction about 5 years ago for $50. No big deal if it's blown... but I'd really like to set up a home theater and I'm hoping this can be made to work. I'd appreciate any help you can give. Charles.
