Problem turning On

The lamp, ballast or dmd board can cause the same problem. Most commonly on these DLPs it is the lamp, but we have to use the process of elimination as well sometimes. Even as a samsung warranty center sometimes the flow charts don't help. The first thing I would do as a consumer is to vacuum around the ventilation holes behind set, these can cuase poor circulation and startup/shutduwn problems. Then with those type of lights flashing start by bidding for or buying the most inexpensive lamp you can get. Make sure exact replacement. Do not touch the glass on lamp when replacing. Then try the ballast which also has a part number on it and has only two screws when you have lamp removed from set. If still no luck, assume it is the dmd board and try pricing that baby. Not cheap! Then comes the decision. New set or repair this. This is what you can expect unfortunately. But I have the same set at home. Go figure.
