I have a samsung LCD lns4692d, and the picture no longer comes up on the screen, i can go through multiple sources get sound but no picture. Usually when you change sources there will be a source name on the screen which does not show up anymore. The LCD is backlight, and you can see when you change channels or sources it flashes, but never a picture. Based on other comments I have taken the back panel of the lcd tv, everyone else who had this issues states this to be a issue with tcon (timing controll board) /lcd controller board. Is this the same board where the audio video sources, antennae and cable plug into? BN94-00963B ASSY PCB MAIN-SPZ LNS4692WX/XAA,AM LCD I have a samsung le52m87bd which has a picture for about 2 seconds when first turned on but the screen the goes blank. Sound stays on. I have seen other posts about another samsung model which seem to say you can replace the t-con board but i am unclear if the problem is the same for this set and if you can get a separate t-con board for the m87 series Any ideas? Thanks
