Réponse à : « I have no picture (black screen). Sound and Ambilight still works. »Hi! Try to disconnect the 51 pin ribbon cable from the T-con board! If you have than color screen looping(white, red, blue, green), than there is a problem with that cable! I‘ve got the same problem, and I solve it with an eraser. I put it on the connection by the T-con Board, and screw back the metal plate! It pushes the connector down, and the picture is back! This is a permanent fix, I don’t know how long it will be, but it cost‘s you „nothing“!
