Question about Sony WEGA KLV-23HR1 23 in. HD-Ready LCD Television
Hi, I have a 46' Bravia Sony LCD, I bought it about 2 years ago. Recently I notice that there is a white horizontal line moving slowly from bottom of the screen to the top, once the horizontal line reaches the top, a new one starts from the bottom again. The horizontal line is not that white, a bit blur, can someone please explain to me what 's wrong, what causes it and how I can fix it and how much it will cost ...Thanks in advance..Hank

Thats a pixel data problem, there's no data being sent to that row of pixels so they don't change color. This is a pixel address registry (PAR) issue and the PAR circuits need to be serviced its usually due to open or shorted SMT components on the PAR circuits. PAR also sends data, voltage, and control to each pixel, the green line you see are pixels that have voltage but because there's no data sent too them their all green because there's no control. If the pixels have voltage but no data or control they show up as green red, blue, yellow, or whit line vertically down the LCD panel. The vertical-horizontal section of PAR are controlled by 16 to 32 bit micro-controllers which may need replacing. If its under warranty take it back if not have your local repair center fix the tv for you...
