SOURCE: samsung le32r black screen
Your problem sounds like inverter has failed.
To prove this you need to remove the back from your tv set.
Then switch it on and look carefully through the small holes on the metal shielding that is directly over back of screen you are looking for bright white light.
If you cant see it easily try doing again but in A dark room.
If you can see white light through the holes in metal shielding the inverter is working & fault is else where.
If no light can be seen problem is with inverter you will need to remove the inverter pcb & check the transformers with ohm meter to see if one is open circuit. Allso look on same pcb for any smd circuit protectors that may be open circuit.

I had the same problem and I replaced the t-con board. My t.v. is fixed!!!! I just couldn't see spending another 700.00 dollars for a repair shop to fix it. The t-con board is located at the top of the t.v. once you remove the back cover. Be very careful removing the two plugs at the top of the board which was easy once I figured out how the clips worked. there is a black lever like connection which flips up, then grip with your fingers the tab and slide the tape like wires straight out. The bottom plug is very simple. Also to expose the t-con board you will have to remove a heat shield cover. Once removed there is foil looking tape that needs to be peeled back to expose the board. The board is very sensitive to static electricity so if you have a grounding strap that you can strap to your wrist and ground to the frame while performing your repair. Its best to lay the t.v. face down on the kitchen table with a blanket to protect the screen. Good luck!

I had a similar problem with my LG plasma. I used the Image Sticking Minimization
(Pixel Orbitor, White Wash, and Inversion) feature which is designed to prevent image burn in and ghosting. This ISM feature may be available on the Samsung or any other brand under a different name. I activated the "white wash" option for about 30 mins, the screen turns white and somehow the pixels get reset. The green noise disappeared after that.
I hope this helps. Phezbuster
