I have the same problem. I brought a Samsung 46" in July 07 and on Jan 8, 2008, video went blue.
I called Samsung and sent out technician and they replaced the motherboard.
Two hours later, same problem occured. I called today and Electronic Company thinks I have a bad LCD panel.

all 3 lights blinking means lamp has a fault the service manual says replace the lamp. If you need the service training manual for that model let me know and I will post the link as the training manual has excellent trouble shooting breakdowns for that model DLP

What you are sseing is a convergence problem within the light engine of the set. This is not repairable in teh field other than replacing the light engine part. Since this unit is less than one year old, it should be covered under warranty. From the looks of it, one of the LCD panels has shifted internally. Call for warranty service and indicate that the light engine has a problem. With luck, the service company will show up with the part in hand. Replacement should not take more than an hour or so.
