Got this Panasonic plasma. TV works fine on HDMI and other inputs, and plays dtv for a short while when switched on from cold. However if an arial is plugged into it - no matter what input is selected - it will reset after about a minute, and then every 15 seconds or so after that. When it immediately comes back on it will be on dtv input ( no matter what you were on before) with sound and tv guide working fine, but no dtv video showing. Video will not show and it will reboot constantly unless you switch off and leave it for a while. But if you remove the arial it will stay on and play other inputs fine.
Obviously a new main board will likely sort it, but I'm interested to see if I can chase down the problem with this one. I've been studying the service manual and probing voltages but haven't got very far with it, so thought I'd open it up to see if you guys have any ideas.
It seems to be related to the problem in this thread where someone was getting no video on dtv on the same model, though it wasn't resetting:
