March,2011 Melbourne Australia 50" Plasma. Purchased December, 09
Had a similar problem with only one HDMI input ( #3 ) of the four working.
When other inputs were connected, whatever signal was working in #3 was replicated irrespective of the device being used.
To fix this I powered down everything overnight( unplugged at the supply ), also disconected all HDMI leads at the TV.
Following morning powered up the TV and added each input and powered them up individually. This fixed the problem.
Because my problem occurred 15 months after the original post above it appears this is a common lock up problem and the fix hopefully will work for others.
