Un plug the power to the Plasma Screen and also to the Media Receiver for ten minutes. Disconnect the off the air antennas both A and B. After ten minutes plug in the plasma screen then the media receiver and turn on wi the remote control. You should now be back in operation. I was.
Also It may not be a bad digital tuner. The TV Guide feature is active even when the zip code is set to all 0s so if you have an over the air antenna attached the TV will look for the TV Guide info and if it can not find it because of a weak signal or the chanel it is tuned to does not carry that information the TV thinks that tuner does not work which triggers the 12 flashes. Also on power up the gray box with the waring message "Plasma Display Starting Up, Please Wait" appears and the screen is blank.

Wow, I've been an installer and salesman in the consumer electronics industry since before the first plasma TV came out (Phillips 42" and Fujitsu 42" in 1996) and this is the first time I've ever seen that kind of an answer. "Take this to a repairman and he can add more plasma" what is the repairman a doctor. If it were that easy no one would ever have to upgrade or replace their screens. You can't add more plasma to a screen, if you don't believe me call Samsung and ask them for yourself like I did. I was actually so dumbfounded by your answer that I called a tech friend of mine at Samsung and asked him, his answer; "does this guy work for you?" I told him no and he said, "I was going to tell you to fire him because that's the dumbest thing I've ever heard anyone tell a customer".
What you need to do is take you plasma TV to an AUTHORIZED Samsung dealer/repair shop and inquire about the hazing/ghosting problem with them.

I have the exact same problem with my 42" LG plasma which is about 3 yrs old. Turned it on one morning and had verticle lines all over it with only the sound playing.

I had the same issue with 2 of these sets. It ended up being 2 capacitors were bad on the power supply. They are located towards the bottom of the board, you can visually see they were buldging and leaking slightly. I replaced them with 2 I salvaged out of an old computer (of same values) and the tv works as it did before.

I had the same problem and fixed it by replacing the control board. It's a little nerve wracking, but required only simple hand tools. If you'd like to see detailed pictures of the repair check out my blog.
