Hello! I have a Sony Bravia KDL-32U3000 TV and a DVB-T decoder connected to it. The decoder is connected to the EURO input AV2 socket. There must be a decoder because the TV has a decoder, but it only decodes MPEG-2. After turning on the TV and the decoder, the word AV2 is displayed on the screen in the upper left corner, and under it a circle with an arrow and the word 2. I do not know how to turn it off, because these are subtitles on a black background and occupy the screen a bit. Second question: on the right side, approx. 12 cm from the side edge, a vertical red line, approx. 3 mm wide, shines on me, is it a matrix defect, can it be removed by yourself or must be serviced. Thank you for the answers.
