The IPboard part no. BN44-0012A is bad. We had to replace 5 monitors with the same problem. If under warranty call 1-800-Samsung for repair or exchange.

If you're out of warranty, you might be able to fix this by replacing a couple of capacitors on the power supply board. I have been doing this the past couple of days to several "dead" monitors with success. I have replaced 820uF 25V caps with 1000uF 35V ones you can get at Radio Shack for $1.69. And 1000UF 10V caps with 1000uF 16V caps. A great indicator of heat problems is looking at the protective plastic shield(s) and looking for melting & black circles. These caps usually have a flat silver top. If they are bad, they either have not top, or the top is popped up. I hope this helps!

I have the exact same problem, but cant find anything in the ways of fixing it. Did you solve the problem without taking your PC in?
We bought 6 of that model and within 1 year 2 of them have developed that problem.
I even tried using the DVI cable and the analog. Screen just goes dark after a few seconds after turning it off and on.
