We have a universal remote and went into the menu and turned off all of the inputs but the HDMI input.

It sounds like your module that controls the menu and the "cycling through" may not be in sync or may needs to be replaced. I had times have had to make sure the Optoma EP716 had to be first plugged in and "on" before the PC can communicate with it. Once the Optoma is "ON", then turn your PC/Notebook on. If there is no connection via USB, "S" cable and/or your VGA (be sure your PC/Notebook is set to have the external VGA "active"). Let me know if this works or not. Then we can try to move forward with other options for troubleshooting. long have you had this multimedia and how many hours of use does it have?...JGUAM

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:

EP716 Optoma Projector Fuse

There is no fuse. I took my EP 716 apart to find out why it died. I found a resistor had blown on the power board made by the Tiwan co. Quazarpower.

Optoma EP716 turns on but no picture displays

Don't ever just unplug the power cord while it is on. The bulb needs to cool down with the fan still on.
Did you ever connect a source?

You can test the power source if you are getting any power input from the power cord itself. Plug in your power cord and use an eletronic meter on the other end to see if you are getting the proper voltage (110/120) reading. If not, then the power cable is bad in itself. IF you are getting power from your cord, it could also be a fuse inside the Optoma and/or where the power plug on the Optoma meets the actual power source is out of alignment or may also be not making the proper contact to the main circuit board on the Optoma. Hope it helps....JGUAM

-toggle the laptop display using the FN keys and F5 I believe. -lower laptop resolution to 800 x 600 -look in laptop display properties for lcd or external display settings, see if it (external crt) has to be enabled on the laptop first.
