Re: samsung un50eh5300f
1) TV is OFF.
2) Keep the black probe of the meter on the chassis GND.
3) Keep red probe of the meter on the first pin (top pin of the connector based on your picture: https://www.badcaps.net/forum/attach...5&d=1500943915) of the LED connector
4) Keep an eye on the meter and then turn the TV on, see how high the Voltage go up to and then wait for about 10 seconds to see how low it goes down to, record that reading. Turn the TV off.
5) Move the red probe down to the seconds wire and repeat the same test again. You will do that on all six LED wires.
BTW, what is the power board P/N? BM44-??????Never stop learning

by signal.questHi all,
I have been working on a Samsung LN40C630K1F LCD TV. On power up the backlights only briefly light up when first powered on then they go out (2 seconds to black). The flashlight test also fails. The sound works fine. Please see attached pics.
I have researched the forums a lot. I have watched the videos of trying to locate the bad CCFL or transformer and bypassing. I can't find any evidence of a bad transformer/CCFL. I verified I get 376V from the big caps to the fuse. I have used a small/cheap oscilloscope and it looks like the MOSFETs on the inverter...6 Photos -
