Yes, some picture settings will lock out the ECO saving feature of your TV set, and if you choose those due to the brightness /contrast settings, you want to select one that you can turn it off, then set your brightness and contrast settings in that choice.
Now, Brightness should be set to 50% and Contrast/Picture set to 100% for a VIVID picture.
Philips built their TV set that way to get the Energy Star rating....but that doesn't mean you are forced to keep it set that way. Philips knew the TV would look better with the ECO settings turned off, but when you buy an Energy Star Rated TV set, they are forced to make sure the ECO settings are turned ON right out of the box, so you have to MAKE your TV set NON-ECO...understand what I mean by that?
All TV manufacturers have to do that to their settings if they want that (not so popular) Energy Star rating.
Somewhere a Tree- Hugger hugs his TV set as the picture blanks out on him because he hasn't touched the remote in the last 45 minutes....
