My shop had this problem yesterday. We had to change the DMD to correct it. One of the data lines was being drawn down intermitently. This doesn't eliminate the digital PCB, but, we have seen the DMD do this more than a digital. You should have an authorized shop do the repair. Contact Samsung at 1-800-SAMSUNG or contact by email: http://samsung.com/ContactUs/ContactUs.htm Hope this helps.

Either the channel up or down buttons on the tv are most likely stuck.

Could be the decoder:

1. unplug the TV ans wait a few mins.
2. If you have digital cable box or dish tuner reboot those as well (likely your issue)

What you have is artifacting what that means is tiling garbiling and freezing this happends when the data in the digital stream just stopped hence Frozen.

Try those things rule out your cable tv box first or your sat box, if this is OTA over the air your antenna.

1. Try DVD's if it happends during a DVD you do have a decoder issue if it does not you need to talk to your cable tv or sat operator.

So you got 3 possiabilites here 1. the worse Decoder, 2 cable company or satalite provider, 3 your antenna is in the wroung position.

I sure this will help.

These are the steps to reset the DTV features and unfreeze your TV:

  1. Ensure the tv is in analogue mode, not dtv and turn it off.
  2. With the remote: press info, then menu, then mute, then power. These buttons need to be pressed sequentially, not all at the same time, and in quick succession. A menu will appear on the tv.
  3. Navigate to the reset option and press the left arrow key on the remote (or press the enter/ok button). The tv will reset itself and turn off.
  4. Turn the tv back on & it'll re tune all its channels. DTV should be working again.
I hope that helps.

Faulty parts on PS board , bad press for Samsung
When checking the capacitors, If they are slightly rounded on the top where the X is, the cap is defective.
Because the Samsung LNS4051D would not turn on and the power
LED would blink 4 times and the relay would click and this
would repeat again and again. I replaced power supply board
parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors,
three had their tops bulged up slightly that I missed on
initial visual inspection. After seeing the reports of
problems with these caps on
http://www.fixya.com/support/t1336881-will_not_turn_or_off ,
I replaced them with Radio Shack part 272-1032, 1000 uf, 35v.
They are slightly bigger, but fit OK. TV is working fine now.
Cost was 4 x $1.59 = $6.36 plus the time. I saved between
$100 to 300 in the process of either replacing the board or
getting the unit serviced. If you are not comfortable
replacing components which means using a soldering iron, you
can replace the power circuit board, available from
www.Samsung.PartStore.com.

It is possible that the TV was hit by a small power surge, and the processor has some garbage in it, and you need to leave it unplug for 40 MIN, and that will reset back to normal.
