Customer Question

Sony KDL-40BX420. No audio or video. Do hear bell when turned on. Standby and power LED lite up as appropriate. No blinking error code, steady red light. Power board connector CN6401 has 3.3VDC at Pin 1 (white wire), and Pin 2 (Green wire). Pin 3 (Orange wire) has 3.3 volts with power on, 0 volts with power off. These voltage tests were performed with plugs hooked up and no cable connected to TV. All readings were taken on the DC range at the meter. I do not have a wiring schematic so please identify wire color and plug or connector number for further readings. Also identify if AC or DC.
