Philips 50PFL3807/F7 When turned on with a flashlight I can see the "Philips" logo then a click and it goes off no backlight what so ever not even a flash. It looks like the inverter board might be built in to the power board?? and at the connector for the lights I only get 4.9v at 2 of the wires and nothing on all the rest and that is only before it clicks off again.
