Hello, I have a Samsung PS51E6500 Plasma TV. It stopped working while watching a 3D movie. The screen turned black, the SmartTV logo came up for about half a second. The screen stays completely black and it doesn't react to anything, including changing channels, opening the menu, etc. The sound, however, does work. When the TV is turned on, there is a slight glow for about 2 seconds, after which the screen turns completely black.
I checked the Va and Vs voltages. They are correct and do not fluctuate. The logic board has a green blinking light that blinks at a pace of 1 a second. I checked...

It doesn't matter which end you put in which place....

You can test the buffer board using a multimeter. Take out the cables that connect the buffer board to the panel. Then, put your multimeter to the diode test mode (it should buzz when the positive and negative ends touch). You should then put the negative end on a screw and move the positive endalong the connectors on the buffer board. If you get a buzzing noise, one of the chips on the buffer board is short circuited. If you aren't getting a buzzing noise, it is most likely working fine....
