I have recently acquired a CRT projector and don't really know what I am doing. I connected my laptop to the projector via VGA and put my computer on the projector mode but nothing will show. I am thinking that I need to change the input on the projector but i don't have a remote control for it so I wouldn't know how to change it.
You can't do anything without the remote, sorry! I have some available, or they do show up on eBay. Keep in mind that this is a really old projector. Check the tube condition before you spend any money on it, Pull the lenses and look at the tube condition:
