I go this TV in June 2008. By Jan 09 the screen started going blank. I called Samsung and I was told maybe it is a lamp problem - they are selling defective televisions. I am worried about what will happen once the warranty is over - I was told an extended warranty would cost $550. At that rate, i might as well just buy a new tvGet more detail about Samsung LN37A550 37-Inch 1080p LCD HDTV.
