SOURCE: hitachi blue patch

I've had one for about a year and a half. This is the second time it happened to me. The first time they replaced it for free(warranty). Now my warranty is up and it is starting to happen again. I think that this must be a common problem in this model. I recommend contacting Hitachi and seeing what they have to say about it. I'm yet to call them again, but I will soon.

My Windows XP is connected to my Epson Powerlite S3, but the screen is blue with the words Source: Computer (Auto) No Signal on it. When I click "Help" on the projector, it takes me to a screen...


'No signal' and 'unsupported signal' messages mean 1 of 2 things, either the VGA output is off(laptop) or the display resolution is set too high(laptop and desktop). Assuming the VGA cable you are using is good, try this:


Desktop: hook the computer back up too your computer monitor & set the computer to the basic VGA resolution. For windows XP, right click a blank area on the desktop, click 'properties' on the dropdown menu, click settings. Write down the numbers in the 'screen resolution' and 'color quality' boxes!

Drag the 'screen resolution' all the way down to then 'less' side. Then change the 'color quality' to the lowest setting. Click apply, then answer yes (the display will look UGLY - don't worry!!) Now connect your computer back to your projector. If it works, then the resolution you use on your desktop monitor is not supported on your projector. Experiment with different resolutions to see which one looks best on your projector. You will need to change the settings each time you switch monitor to projector.


Laptop: by default the VGA connector on your laptop is off. To turn it on, look for a blue symbol on one of your function (F1, F2, F3...) keys. It looks like an old TV with a line on both sides 'O' (F4 on HP) Press & hold the blue button (on the lower left of the keyboard, usually to the left of control ) and tap the bleu button you just found. Let go & give you're a computer a few seconds to change over. If the laptop screen goes blank, you found the correct button! The display image should now be visible. Repeat this 1 to 2 times to change it back to laptop display.

If you did not see the display on the projector, 2 other issues are possible. First, verify that the VGA output on the laptop is working - connect the laptop to a regular computer monitor & change the display resolution to the lowest settings (see desktop above), then try it again on the projector. If you cannot get an image on a computer monitor, your laptop settings may need to be adjusted in the same dialogue box as the settings. Monitor #1 is the laptop display, Monitor #2 is the external output.
Happy viewing :)

I my projector is new one used for 4 hrs, when i try to turn it on it just has a blinking green light. Please help Solve It! .


The blinking green light means the unit is either Powering On (Warming Up) or Powering Off (Cooling Down).

Powering On the Projector
1. Remove the lens cap.
2. Securely connect the power cord and signal cable. When connected, the ON/STANDBY LED will turn Amber.
3. Turn on the lamp by pressing " " button either on the top of the projector or on the remote. The ON/STANDBY LED will now turn Green. The startup screen will display in approximately 10 seconds. The first time you use the projector, you can select your preferred language from quick menu after the startup screen displays.
4. Turn on and connect the source that you want to display on the screen (computer, notebook, video player, etc). The projector will detect the source automatically. If not, push menu button and go to "SETUP". Make sure that the "Source Lock" has been set to "Off". If you connect multiple sources at the same time, press the "SOURCE" button on the control panel or direct source keys on the remote control to switch between inputs.

If you are still unable to get the unit to turn on, try unplugging it for 10 minutes and plugging it back in. If it still ceases to work, contact Optoma here: http://www.optomausa.com/rma_policy.asp

Searching for signal


The problem is with the computer, not the projector.
There are special function keys, generally with blue lettering along the top row of your keyboard. Find the one that looks like a double screen or says "CRT". Also locate the blue function key [FN], probably on the lower left on the keyboard.

Press, and hold, the [FN] key and press the [CRT] key to change to dual screen.... and wait for several seconds for the projector to detect it. If it still doesn't work after you have waited, press the key sequence again (there are 3 different screen settings).

1. Computer Screen only (normal)
2. Projector Screen only
3. Both Computer AND Projector screens

Blue Screen


You may have inadvertently switched your projector to a different input mode, or the mhz refresh rate, etc., Jon.

Projector does not display laptop screen


Many laptop computers do not automatically turn on their external
video port when a projector is connected. On many laptops, the activation function key is labeled with an icon or the text CRT/LCD.

Try the Function Key with the Icon of a monitor to enable the external video port.

If that does work, look at the settings on the projector using the buttons on the top.

Check the "Default Source"

Default Source toggles among Computer 1 analog, Computer 1 digital, Computer 2, and Video. This determines which source the projector checks first for active video during power-up. Highlight Default Source and click the left or right mouse button to toggle
among the options.

Blue patch on left side of screen


I had the same problem with my Hitachi PJTX100. I discovered that there was considerable dust build-up inside the unit, causing insufficient venting of heat which then damaged the color prism/filter. It was close enough in time to the warranty for Hitachi to cover parts replacement (approximately $1,600). Since the repair, the blue patch is gone. I also regularly vacuum not only the outer cover but also the inner air filter that easily snaps on and off.
