Panasoni viera EC/HDMI keep popping up on left of screen

EC means external connection
EC/HDMI means external connection on HDMI input

if you call the toll free number on manual they will be at your house

Ive got this problem too. Anyone found a solution?

This is a dead short, check power supply for diodes bad or zeners

Inspect for damaged pin on INPUT 1 socket. (left most of the three HDMI connectors)
A quick pull on the cable can damage the pins.
=== If you see mis-aligned pins then please power off the set before making corrective action. ===
============== Here's a textbook instruction from Mitsubishi
If the New Device Found Screen Displays No HDMI Control Option If the New Device Found screen shows no option for HDMI Control, one of these conditions applies: • HDMI Control is turned off in the menus of the new device Action: a. Highlight EXIT and press ENTER to close the New Device Found screen. b. Display the device's setup menus and enable the device's CEC capabilities. c. Wait for the TV's New Device Found screen to appear again. d. If the New Device Found screen does not appear, power off the device. Power on the device and wait for the New Device Found screen to display with the HDMI Control option.
Next time you see the NEW DEVICE FOUND screen pop up.
Toggle the CEC field (on the right side of the pop up) to OFF.

You can buy an HDMI to DVI adapter (around 20$) to connect your HDMI computer cable to your TV. You will need separates audios cables, right and left, to bring the sound to the TV.
