Some more background here. I had the HDMI go out on my other TV which is Sharp LCD TV while hooked up to the STB. That TV is now hooked up via component and works fine with no issues. I thought that the issue may have been a STB issue with HDMI but it seems like a co-incidence. BTW I had the HDMI checked out by a Sharp authorized service person who confirmed that the HDMI board is infact bad and needs to be replaced for $300. (too expensive)
Also, any thoughts as to the second part of my question regarding vewing and resetting the STB's in my account?
