I have a 39 inch Samsung TV that is only two years old. When you press the power button, it sounds like it it turning on and the red light comes on but the screen is black and there is no sound. I've tried different outlets, unplugging everything, etc... I tried shining a flashlight on th screen and I don't see the menu screen. I only have "back lights" when I unplug a wire that goes from the power board to the main board. Any suggestions?
Main board is bad since it works with both video and audio. Ur backlights are ok so that omits the inverter board. And the T con board is for video only - since you have hassles with audio and video that leaves the main board. Do not think it is the power supply since your inverter board is powering up the back lights.
