This article will walk through some troubleshooting steps to take if the projector is showing no signal.
If projector screen is blue, or has a Life.Church logo and no signal in the bottom left corner
Check this by looking at the bottom left corner, underneath where it says "No Signal".
If it is set to anything other than HDMI, use the EPSON remote to select HDMI as an input.
If HDMI is selected, make sure that the system is powered on.
The easiest way to check this starts at the rack that is below the desk. At the top of the rack, look for a green dot on the power conditioner. This is labeled "1" in the picture below. If this is not lit up, flip the power switch next to the light to turn the power conditioner on.
Sometimes the video systems just needs a kick in order to recognize the Roku. Unplug the Laptop, and you may see the Roku screen pop up. If the Roku screen does not display on the projector after unplugging, please continue the Video Signal Flow Troubleshooting section below.
Before starting this section, make sure to have a flashlight ready to go!
If you can see your HDMI switcher, lets make sure that it is also powered on. If powered on, you will see multiple green lights on the front face of the switcher.
While you are looking at the video switcher, use the picture below as a reference of which green lights should be lit up, and which should not.
If the green lights do not match this HDMI Switcher, please contact the Tech Help Desk: (405) 216-2846
If the correct green lights are lit up, make sure that all HDMI cables are securely plugged into the back of the video switcher.
The next component in the chain is an HDMI Splitter. The splitter should have a Red light on it. If the red light is visible, just make sure that all 3 HDMI cables are securely plugged in. If the red light is not visible, make sure the power cable is securely plugged in.
There are 2 HDMI cables on the right side of the splitter, right by the power cable, and 1 HDMI cable on the left side of the splitter.
The last component that the video signal passes through before going up to the projector is a red video converter made by Decimator.
Settings are nearly impossible to change on this because of it's location, so just make sure that the decimator has power, and that both the HDMI and SDI video cables are plugged in securely.
A quick and easy way to make sure that the Decimator has power is to look at the screen that is on the top of the unit. Most of these screens are set to stay on all the time. If the screen is not lit up, hit any of the four rubber buttons on the top of the decimator. If the screen lights up, the Decimator has power.
If the Decimator screen does not light up, locate the power cable that is plugged into the front of the Decimator, and follow it until you see the "wall wart"(shown below) at the other end. If it is plugged into an outlet securely, please contact the Tech Help Desk: (405) 216-2846.
If after going through these troubleshooting steps, you still do not see video on the projector screen, please contact the Tech Help Desk: (405) 216-2846.
The next indicator is the LynTec power light. LynTec controls most of the A/V system power in each room. The rack will have a "Fire It Up" button, an On button, or yours may be controlled by a light switch. Make sure that the light switch is in the On position, the green On button is lit, or if you have a "Fire It Up" button, go ahead and push that button just to double check that LynTec is all powered up.
Once the system is turned on, if you are still not seeing video, plug in a Life.Church Staff laptop to the open HDMI cable that is on the desk. If you see the laptop screen come up on the projector, click here.
If the laptop screen does not come up on the Projector, click here.
If screen is black and does not display LC logo or "No Signal"
First, verify that the projector has power. The easiest way to verify this is by looking at the blue indicator lights that are on the bottom of the projector.
If the projector is powered on you will see 2 blue lights on the bottom.
For more info on what each light indicates, click here.
Then check to make sure the video source (Roku) has power, and that the HDMI cable is securely plugged into the back.
Check to make sure that the HDMI Switcher is set correctly. Use the image below to reference which green lights should be lit and which should not.
If the green lights do not match this HDMI Switcher please contact the Life.Church Tech Help Desk: (405) 216-2846 as changing these can get complicated and we'd love to help!
