I just got a free Sammy Plasma model PN58B550 from my company, the TV was always mounted on a wall in a conference room and used intermitently, not to excess by any means. One day they went to turn it on and nothing, no blinking lights, no clicks, no power up sound. I took the back off and tested voltage to the power supply and past the first 2 fuses, that was the extent of my troubleshooting however power is flowing into the power supply. To the right of the power entry to the power supply there is a small unlit light bulb on the power supply board when power is present and passing into the supply. I assume this being unlit poses a problem with the power supply? I ordered a new power supply that I am waiting on, what else should I check for if this isn't the problem or am I on the right track?
