AC Power to TV

257 Views 3 Replies 4 Participants Last post by  canue
My friend has a SONY HD WEGA TV (don't know model, but it is 36"). He recently got cable and the installer plugged the Sony into the cable box, and set the cable box so the AC outlet is only live when the cable box is "on." He told my friend to just turn the cable box on and off and it will also turn on/off the TV.


To me, this is the equivalent of unplugging the TV every time you turn it off. I am under the impression that most of today's electronic equipment continues to draw a small amount of electric current even when off and that current is there for a purpose - memory, keeps some settings alive, maybe keeps some components warm.


So my question is - should I get my friend to change his setup so he turns off the TV with the TV's own on/off switch (on the remote) or is it ok to always have the set "unplugged" when it is off? Your assistance is appreciated.


(Sorry if I posted in the wrong place, but I could not find a better spot, and this does involve a direct view set).

Unless the cable remote can be set to give the TV an "on" signal, I don't see how just turning on the cable box would also turn on the TV. Just giving the TV power won't turn it on, unless it has a "hard" switch instead of a remote switch. I would say that if the TV is designed to always have power, then it should be used that way.

On some TVs at least, if you unplug it while the power switch is on, the TV will turn itself back on when you plug it in again so when it's plugged into the cable converter's auxiliary receptacle the TV will automatically come on when you turn the cable box on (i used to have my old Sony Trinitron connected this way).


I don't know if this works on current TVs or not, and i don't know if it harms the TV or not but i did it this way for a few years and had no problems, but i don't think i'd want to risk it with a new expensive TV.

Dougf my HDTV has 3 fans running when on, after watching my movie I turn off the AC current within 3 minutes for the hot air to cool. I have 22,057 hours of watching movies and the current is stopped every time. Using this system I am able to have this HDTV running years after other sets have gone to the junk pile, there is another AVS member who does the exact same thing I do. We save the fan from running 24 hours a day, like your/our computer the fans stops when you safely stop the power saving your settings, the HDTV works the same way. 22,057 hours is equal to 2.51 years of being plugged in. You have to believe that companies like RCA, Hitachi Sony know what they're doing, we created a way to extend the life of our premium view with the built in integrated line doubler if turned off, until next time this turning off the AC will add many more years of watching movies. I do not by choice subscribe to any commercial *filled* Cable or Direct TV, it was bought to view DVD movies not commercials AKA SPAM. Ask around the members who know, know that the components although the AC has been shut off still keep memories that were programmed into it.



Example if I watched a wide screen movie the last time when turned on again, it will be set for another wide screen movie, 'only' the clock won't be set to the right time, who needs yet another clock to view IMHO. :)
