Hi @marcuss1357 , You haven’t said what else you have tried besides changing the power board so I don’t know what you’ve have or have not tried. By no power do you mean that the TV’s red standby light is not on? Have you checked that the power is getting to the TV by connecting the TV to a known working power outlet or trying a different compatible known working power cord? Have you checked that the standby voltage at the Standby power reference point as shown on the power board is indicating the correct standby voltage? Disconnect the power from the TV and then disconnect the cable between the power board and the mainboard. Reconnect the power to the TV and turn it on. The TV backlights should turn on full and stay on. There will be no picture because the mainboard is disconnected. The power board is turned fully on when doing this procedure. Be safety aware if you decide to try this as there is exposed lethal voltage in the back of a TV when the back cover is removed. Turn off the TV and disconnect the power from the wall outlet, before doing anything else in the back of the TV If the standby voltage is OK on the power board and the backlights turn on and stay on, then most likely the problem is in the mainboard. It turns on the standby red light when the power is connected to the TV upon receiving the correct standby voltage signal from the power board. There is also the possibility that it could also be in the cable between the mainboard and the power board so check that it is inserted correctly at both ends etc.
