Question about Pioneer Televison & Video
I have a Pioneer PDP-LX5090, Kuro Flatscreen TV, connected via HDMI4 on a Pioneer AV-receiver VSX-LX60.
By connection a Chrome cast on one of the HDMI ports of the AV-receiver I got the same CEC100 error with the same message "device cannot be operated. please check the connection". By disconnection the Chromecast from the USB current feed, the problem dissapeared. Hope this can help you.

It operates, but that annoying message box keeps popping up every 10 seconds!

SOURCE: displays error code cec100.
CEC100 is a system by which many devices connected via HDMI may control one another. The error message indicates that one or more devices do not support this protocol. In this case, I venture a guess that the error message is appearing because your TV does not support the CEC100 protocol. It should not prevent the machine from playing, it is simply is notifying you of a communication failure.
