Blinking lights on Motorola digital box with no picture or sound

SOURCE: DVR/TV connection

With the RGB you have to run seperate audio ,I think you have ran the seperate cables for the sound but they are in the wrong place.try changing the RW from the DVR to the TV and you should get sound from them.The unfortunate truth about the HDMI is that the HDMI format has a problem effectivly communicating between components.I am a Directv certified High Definition technition and %50 of the TV's that I connect the HDMI to will not receive the signal.One trick that I have found that works is to make sure you have a picture on the RGB then connect the HDMI.Once you have these connected ,turn your TV off and unplug the power cord from the DVR for 30 sec then plug the DVR in and wait 5 minutes for it to power up then turn your TV on and switch to your HDMI input.This method sometimes works to "Jumpstart" the HDMI input on the TV .There is no guarantee that this will work but is sounds like for now this is your only option,GOOD LUCK.
