My LG TV (model 49uh6100) backlight was purple so I changed them all out with new LED strips. Now when I turn the TV on the backlight kicks on but I don’t have any picture at all.I have triple checked all of my connections and replaced the main board and the t-con board but I have no picture at all. Not even the LG logo comes on when I turn the TV on. Does anyone know what else I should try?

Hi Did you fix this issue as I have the same problem and have tried exactly the same as you I.e. T-con board, power and main PCB’s? My TV is a LG 47lb580v though. Thanks ?
