Samsung SPP4231 42-Inch Plasma TV with Installation
Blackout problems
I've had the set about three weeks and have already replaced the main circuit board.  The problem is that the screen and sound disappear for about 5 seconds several times an hour.  The new board has slowed the problem but not eliminated it;  it now blacks out about once an hour.   <br /> <br />I've replaced my cables and my satellite box but nothing changed.   <br /> <br />When it works the picture is amazing considering the price and the fact that this is EDTV.  The sound through the provided speakers is adaquate.
