Go to:

System Preferences (you can get there by clicking on the Apple Menu in the top left corner) -> Displays -> Detect displays

After you click "Detect Displays" your G3 should automatically send the display image to your projector.

I have the exact same problem with my LP-755 projector !
Just then PC input detection works but no RCA A\V detection or S-VIDEO detection...
I'm looking for the service manual of this unit - can anybody help or refer to a download source ?
Even a simillar units electric-diagrams could be very helpful for troubleshooting !
The inside (video inputs) controller PCB model number/barcode is 510-1457-06 00
There are also daughter boards with EPSON name on them.

There are a bunch of steps I could walk you through to detect the projector and then set the correct resolution and color depth. But it will be easier to have you just attach the projector and then restart the laptop so that the system will attempt to re-detect the second display automatically.

Then just right click the desktop and select properties. Go under display properties, settings, and enable the second screen (2) as either a cloned or extended display.

Computers do not generally send an RGB signal, you should be connected via a VGA cable between the projector and the computer. The input menu on the projector should be set to VGA. The output of the computer should be equal or lower to the maximum resolution of the projector.

blow the dust out of it with canned air, make sure the fans are all spinning. this should remove the causes of overheating. if it still says that it is overheating, replace the thermal sensor (usually near the lamp or the lamp fan).

Verify that the autosource is selected in the system menu

I have the same problem with a Hitachi CP-X345 Multimedia Projector. My Acer Aspire 3630 Laptop cannot be detected but it works without incident with a Dell Vostro 1500; just plug and play. Desktop settings to second screen doesn’t seem to help.

Hi,

I am not understand the exact problem.
Can you pls explain briefly about your problem?

Try going to system preferences - displays and see if your macbook is detecting an additional display.
