hello problem on the tcon card, look at the peer signals sent by the scaler circuit from the tcon card connector, those lvds signals can be 5 pairs for hd panels and 10 pairs for full hd panels, fix the coils or surface resistances so small that receive the signals lvds verify with the instrument in the 5 signal pairs or 10 pairs if there are low voltages that are around 0v to 1.2 or 1.4 v, if in some of them it exceeds a higher voltage such as 2 volts, that tells you that you have an open coil ok, greetings
hello paisita tobiastv of course it could also be, I hope that the colleague arturo can solve problem greetings dear friends greets you the paisita melcochita el dulce
