Can anyone help. I just set up a watch TV activity on my Harmony One. It switched on my Foxtel IQ2 and Sony amp but really upset the TV.

The TV had been set to PC input before being switched off.(I have a media centre PC connected as well)

When the TV switched on it was locked to the PC input but only came on approx 1 second every 30 seconds. I eventually had to switch the TV off and unplug it from the wall for an hour before it would work correctly.

Don't want to try the watch TV feature again in case it locks up again.

Using the HArmony in device mode works everything OK.
