I have a 32" Samsung that will not turn on. I have power. The power button will light and flash like every other samsung when it starts. I do not have back lights or a tone when the tv starts. The power supply it built into the main board. When powered on the digital audio out lights up. There are two blue led lights on the t-con board. If all hooked up both lights stay on steady. If either lower cable to the screen is unhooked only the top light lights up. I have unhooked both lower cables, the cable to the t-con and unplugged the led lights and still no power on chime. I believe this is a bad program on the main board. Testing showed these voltages on the pin outs.
