Sony Presence Sensor
May 30th, 2010 by Chris MHere’s a quick FYI just in case you own or are thinking about buying one of the new Sony EX700, NX700, and NX800TV sets. These HDTVs have a “presence” sensor built-in that detects people or motion in the room. If nobody is detected, then after a certain amount of time, the back-lighting shuts off to save energy while leaving the sound on. After 30 minutes of the back-lighting being turned off, the entire TV will shut off if no presence is detected.
The Presence Sensor is capable of detecting vertical and horizontal movements.
Although this is a great feature for energy conscience people, it may catch some customers off guard. The presence center is already turned on when you first take the TV out of the box for the first time. If you have a tendency to sit very still while watching TV, you may experience the screen shutting off.
This can be defeated in the setup menu under “eco” settings under “presence sensor”. Simply push “Home” on the remote, select the “tool box” icon, then press “Preferences”, then select “Eco” followed by “Presence Sensor”. There are quite a few adjustments you can make or you can simply turn the sensor off. I think it’s great that Sony is making their TV sets green and their goal to conserve electricity is commendable. Perhaps on next year’s model, however, they can leave this setting deactivated initially or better inform the customer on this new energy saving technology to avoid confusion.
