Samsung 2233SW comes back on for a second (shwoing the screens) and then goes blank.

I have the same problem with mine. The screen will constantly go black, go to DVI, then back to VGA, then the picture will come back I am using VGA input. The power led will even go out and come back. I tracked the problem down to the button control board. Only the power button seems to work, the others are ignored. Sometimes it will go into the menu and act like the down arrow is being held down cycling through options. What is strange is that I tested all buttons with a voltmeter and they work properly. If i disconnect it, the picture will stay normal. MY board part number is BN41-01084A I have the same problem with mine.
