I would recommend that U check the EPG Auto refresh Setting,,,is on or off.
In my Vu duo, after making stand by,,,, on the next day when I turn the TV on, can see the clock ( P. clock plug-in) on the TV screen only ,but other remote functions do not work, unless I press the on button, then the Vu is on and BH image is completely running,,,!
Is this whats going on with U,,,or else?
Just did I test on an other image , and the result is the same, so its not an image issue!
