Re: UN49KU7000, has sound but no picture
2 and 4 read 362. As I held the multimeter on 10 and 12 together the left side of thebacklight stays on but once I remove the multimeter it goes off again....Last edited by hamlin86; 01-13-2019, 08:49 AM.Leave a comment:

Re: UN49KU7000, has sound but no picture
Okay I tested every pin. Only 2 them gave me readings. It's the first two on the top so it would be pins 2 and 4 or it's pins 1 and 3. No other pins have voltage....Leave a comment:

Re: UN49KU7000, has sound but no picture
I’ve attached pictures. The dc363 is on the one with the triangle (+1). The 291 dc rating is on the -1. I am unsure of where the -2 is. Hopefully my pictures can help you identify if I am doing anything wrong. Also this is the voltages with the tv on....Last edited by hamlin86; 01-11-2019, 11:26 PM.Leave a comment:

Okay I tried that and got 361 dc voltage and 630 ac voltage. Is that good?...Leave a comment:

Re: UN49KU7000, has sound but no picture
Okay I'll go get a multimeter today after work.
Quick question...
In my 3rd picture (the picture of both boards) there are 2 ribbon cables connected to the mainboard and they are going into something. What do those do?...Leave a comment:

Re: UN49KU7000, has sound but no picture
When I get home from work today I will try it out.
If the backlights stay on I assume it's the mainboard? What if they don't come on? Does that mean it could be the power supply board?...Leave a comment:

UN49KU7000, has sound but no picture
Hello,
I want to apologize for the very vague synopsis of my issue. I do not have the tools to test voltages either...
I got this tv about a year ago. About 3 weeks ago while watching Netflix a random black line showed up vertically. It wasn't solid so I continued using the tv and just dealt with it. 1 week later it was gone and all is good...until last night. I turn on the tv and now I have no picture at all! I can hear sounds from the menu but no picture. I did the “flashlight test” and I can see a faint image of the menu in the dark when I shine a flashlight... -
