If the EDID was recorded successfully, then the 

Power LED will glow solid green. 

If an error was encountered during the recording process, then the Power LED will 

flash bright red.
If an error is encountered, disconnect the 5V DC power supply from the booster, 

power-cycle the display, then repeat steps 5 and 6.  If an error is encountered after 

several attempts, then this may indicate that the sink device has a bad EDID.
