My Panasonic experienced what probably was a power surge event. Now I can't get a picture through any of the three HDMI ports or the VGA port. TV is all digital in Norway so I don't know if the antenna input works.
When selecting the HDMI ports, the entire screen is black except for the HDMI-label in the top left corner of the screen.
When the VGA-port is selected the VGA-label is displayed, but there is a vertical bar of multicolored madness on the rightmost 15% of the screen.
What I've done so far:
- Verified all voltages on the power board
- Checked all the fuses on the power board
- Ran test patterns as described here
- Tested that all user menus and service menus are working
- Ran self test, all ok. See attached image.
Any input on further troubleshooting is much appreciated.
