Re: Samsung UN32F5500 LED TV Backlight issue
Let me know whr the voltage from Pin 12 is fine and 0 V from pin 4, 6, 10 is expected.
Only if the o/p voltages from LED drivers are fine i will have to further troubleshoot with LED strips, Right?Leave a comment:

Samsung UN32F5500 LED TV Backlight issue
Hey All,
My Samsung LED TV 2.5 Years old failed to turn on.
Flash light test passed. So the issue is with Backlight.
I need help in further troubleshooting.
Need to check if the led driver output voltage is fine.
Then to check the led strips.
I dont want to go back to samsung service center again, their charges costs almost a new TV. -
