Default Re: Sceptre X505BV - Logo appears for 1 sec then backlight shuts off, LEDs tested goo

Yes, I did take the panel apart because I too initially suspected faulty LEDs. The tester was showing about 79 volts I think, on each array. The TV has two separate LED arrays, one on each side. I illuminated each array separately with the tester and they both showed the same voltage. This is what caused me to step back and second guess myself, because I would expect one array to have a different operating voltage if it had bad LEDs. Each and every LED did in fact come on, although not at full brightness like neilc6 mentioned due to the current limit of the tester.
