Hi. Last Saturday, the TV suddenly started to flash, I read here that it could be the backlight LEDs and I dismantled it and found two damaged LEDs with different strips, although from the same set. I have already ordered the strips and when they arrive I will change them. What bothers me is the following: Having blinked the tester I could not measure the output voltages to the LEDs, but disconnecting and measuring I saw that one of the outputs (+ and -) took 170V and another 140V. Is it normal for there to be so much difference? Also say that the set where the broken LEDs are is 170. Can the problem come from there? The pcb that draws the power is this: EAX65423801 (2.1) Rev2.0 Thanks in advance.
