Today's Device Guru reports the resolution of that issue. As suspected, the problem was with the EPG and there is a way to turn it off — now documented in that story. The problem is probably not unique to Sony or TV's that claim Energy Star compliance (devices are self-certified by the manufacturers!), so investing in a power meter is likely to have a good return on invesment. (Device Guru has a link to an inexpensive meter.) As a result of this waste of power, the EPA is planning for future versions of the Energy Star requirements to limit the amount of time a TV can spend in Download Acquisition Mode (DAM) as the time for acquiring the EPG is known."
