Blue screen "HDMI 1 no signal"


Step 1: Check Projector Source

Ensure that the projector is set to the correct source:

Press the "HDMI 1" button on the top of the projector's remote to select HDMI 1 as the source. If there's no response, try selecting HDMI 2 instead.




Step 2: Activate Lü System

Using the Lü remote, press repeatedly on the spacebar for 5-10 seconds until the screen turns on. The Dell logo should appear on the screen. 


Step 3: Re-sync Lü Remote

1. Turn off the Lü remote.
2. Hold the "F1" key.
3. While holding "F1," turn the remote back on, then release the "F1" key.

This action should sync the remote back to the Lü system. The amber light will start blinking faster but should stop after a few seconds when the remote is synchronized.


Step 4: Reset Lü System 

1. Turn off the projector.
2. Locate the breaker to which the Lü system is connected.
3. Switch off the breaker and leave it off for 4 to 5 minutes.
