No power, no standby light - standby voltage is present though.
I have a 65x900f that will not power on using either the power button or the remote. I have confirmed that standby power is present on the power supply board where the cable leads to the main board. I have also confirmed that the standby power makes its way to the main board connector. One thing I have noticed that is strangem, is that the “power_on” pin on the power supply board constantly reads 3.5V. This doesn’t change when the switch is being pressed. There doesn’t seem to be power going to the TCON board, there is a 12V signal going to the LD board , but the LED_VCC are (obviously) not getting the 12V that they require.
