Got this TV. Owner said the screen went dim so he turned the backlight up to counteract which worked for a while but eventually it went almost black.
The LEDs are lighting up only just, three of them not at all on one strip. Have tested all the LEDs following ReeceyBurger's excellent video instructions and they all light up nicely. Voltage to the LED string from the PSU is only ~105V. I think this should be closer to 150V for 45 LEDs am I right? So I think this is a problem with the PSU. Just wondering if any of you have come across this before and can save me some time chasing down the problem.
Thanks!
