I have a 32" Protron LCD Flat panel TV. Yesterday it did not turn on. I suspect it might be the AC adapter box since the purple light on the box that is usually on all the time was not. I do have power from the wall outlet to the right side of the adapter, but I do not know if or how I can check the four prong plug coming out the other side to see if any power is coming out the other side. Does anyone have any ideas ?

Thanks.
