I have had mine for about 10 days now, and when it is good, it is very very good. However it has the following faults/characteristics and I wonder if others are experiencing these, or should I ask for a replacement? 1. "Personal" smart picture setting When I switch from STB to analogue tuner, or to video, and then switch back to STB it is necessary to manually re-select "Personal". Very aggravating as it is reverting to "Soft" each time. 2. Volume control Frequently the TV responds to the remote request for less, or more volume, and then stops responding. I can see the blue led on the TV flickering so it is picking up some command from the remote, but not responding. I can press the remote for 15 seconds, changing aim but no response. 3. Audio resonances At mid range volume settings, the wrong material can generate significant resonances in the TV, making the sound very unpleasant. I had planned to get some beefier external speakers anyway but I find this performance very poor. NE1 else get the same faults/characteristics?
