Re: LG50LN5400 Backlight Issue
Yes. looks like the LEDs then. I will have to get down into the set and take a look at the LEDS then, I was hoping to avoid that job. Looks like Shopjimmy is out of those parts though. THX

Re: LG50LN5400 Backlight Issue
Power on, connector re-connected, measured from chassis gnd to both pins on connector marked LED +, each one read 90V when powered on, then trickled down to 0. Shorts in the LED strip?Last edited by sgabrie8544; 02-18-2016, 04:04 PM.

Re: LG50LN5400 Backlight Issue
Power on, Led strip connector out, chassis gnd to both those LED DC test points = no voltage! How common can that be, I dont get it.

Re: LG50LN5400 Backlight Issue
No, I measured at the 2 test points right under the connector with respect to their individual gnds, with the connector removed. I got nothing.

Output to the LED strips is the small white connector I removed and measured for voltage to the LEDs....

LG50LN5400 Backlight Issue
Greetings!
I seem to have the "rare" (LOL) issue of the LED backlight being out also. TV powers on, Audio there, flashes quick and no pic. I can see it somewhat if i look on an angle and use a flashlight.
I removed the back cover and disconnected the connector from the Power/LED power PCB to the LED strips and I still read NO DC voltage at the 2 outputs of that connector.
Should I replace the Power/LED PCB or could it still be a LED strip?

Re: Lg50ln5400
I have the same issue on a LG50LN5400, i disconnected the connector from the power supply pcb going to the LED strips and I still have no DC voltage at the connector on the power supply PCB. Should I replace the power supply pcb or could it still be an LED strip?
THX
