i had an elaborate built in constructed for my family room and had the grand wega 60" enclosed. the sensor in the upper right corner was left open in order to change channels, but what i have found is the side must be open a bit also, which i had not planned on. i know i can use other devices to change the tv channels but what about turning the tv on and off. for now, i have just moved the tv out a bit. any help will be appreciated. fartman in las vegas
