There are 2 options. Either something is loading the clock and data line or the micro is not responding to the on command. I do not believe that this model can be powered on with the t-con board removed. Either option the main board, A board, would most likely be the problem. The A board part number is 185759331. This board does not come with some software loaded on it. The t-con on will not come up until after the set comes on.

Thank You for your answer.I have a question for the same set.There are no front panel lights under any conditions,if you try to turn the set on or if the set is off etc.When you plug the set in the relay closes,power board powers up,there is a bl-err voltage of 3.3 volts,there is no back lights or high voltage.When I unplug the large plug from the power board to the a board bl-err voltage goes away.Will this info change your diagnosis any. Thank You Larry Jerome.

I would still suspect the A board. The A board does not come loaded the some software that is only available to authorized service providers.
