Box Display Screen Messages (EFO1 and dU1)

On both of our HD DVRs we have continually scrolling display screen messages -- EF01 and dU1. 

We have reset the boxes and checked our messages, but it is not fixed. Any suggestions/thoughts?

What type of connections do you have between the STBs and TVs?

What type of TVs?

Where they working before?

Did they both start doing this at the same time? If the software update was loading and was interupted it could have caused issues.

Could be a handshake issue on the HDMI cables if the Software in the DVRs was just updated. It may have worked with your HDMI and now does not.
