Daewoo Tv ,Model - DMQ-2975, is having a picture problem that the sound is normal, but the picture is narrowed horizontally (by the right & left side it is narrow & it's sides are curved). I have checked some capacitors arround the HOT but they r ok. So would you please help me with what to do or check or change ?
