No backlight issue. Have sound and can see menu with flashlight.
Suspect LED driver, voltages are 100V each side. What should the voltages be for 75 inch TV on the Power Supply Board? I have 96 leds x3 volts per=288/2=144 volt per side?
Am I low on my volts causing the leds not to light up?
Before I got all backlights out, the right side was a bit darker than left side. How many leds
need to be out for all to not work?
Thinking of getting a led tester. If leds light up, would that confirm it is the Power Supply Board?
I do not want to dismantle entire board to get at leds at this time and hope to diagnose it is not.the PSB
Thanks for any help guys!.
