Mitsubishi WD-82737 HDMI Input Switching Problems

I've had my WD-82737 since Oct. 2010 and Ive had to do a "menu 123 reset" 3 times.  The TV would flicker and not recognise one of the HDMI ports until I reset it.  Not always the same port.  Sounds like a software or firm ware problem.  Could this be a hardware problem? 

Also even though I turn off the antenna input it reappears.

Any advice will be greatly appreciated.
