Question about Hitachi (DT00431) Projector Lamp for CP-S370W, CP-X380
Suddenly, my Hitachi CP-X380 can't find my pc on either RGB1 or 2. I have changed cords, rebooted, etc. and still no image. When rebooting the laptop the Windows logo will display but when it finally gets into Windows, it says "input not found". Any suggestions? Thank you.
I see this all the time.
Since you have a display BEFORE Windows boots, but not after, it sounds like you don't have a problem with the projector, but instead with the video output of your laptop. This is controlled by Windows once it boots. This 'sudden' problem usually happens after you have installed new software, or updated existing software. The new code alters the default setting for the video output.
To regain signal output to an external monitor or projector, you need to adjust your video signal settings. On most laptops this is done by holding down the FN key (lower left corner) and pushing either F4 or F5 (look for a pictogram of a monitor or 'lcd/vga') and releasing both keys at once. You may need to do it more then once to find the right combo of outputs. Unfortunately, you will probably have to do this every time you boot the computer.

First find someone you know who has a working unit, just to make sure you don't have a problem with your PC output or the cable so you KNOW you have signal at the input.
If no signal then, make sure your input is "configured" correctly in the user menu.
I would have to think your VGA input board on the projector is faulty but let me know what you find.
