Re: LG 65uf860 Black screen, no sound. Gets an error code from the power board
Would these resistors work ?
Do you think replacing the mainboard would fix the problem ?

Re: LG 65uf860 Black screen, no sound. Gets an error code from the power board
Here are the numbers from the powerboard. Do you need them from the mainboard as well ?
At standby:
[B]Row 1:[/B]
Pin 11+12 = 3,54 V
[B]Row 2:[/B]
Pin 11 = 3,54 V
When turned on:
R[B]ow 1:[/B]
Pin 4+5 = 25,4 V
Pin 7+8+9 = 11,73 V
Pin 11+12 = 3,5 V
Pin 13 = 3,3 V
Pin 14 = 3,5 V
[B]Row 2:[/B]
Pin 5+6 = 25,4 V
Pin 8+9 = 11,73 V
Pin 11 = 3,5 V
Pin 13 = 3,3 VRe: LG...

Re: LG 65uf860 Black screen, no sound. Gets an error code from the power board
At picture 4 called "Tcon" there is a change. With 4 and 5 (the ribbons at the tcon) connected the voltages are near 0, but if I disconnect both pin 1 goes up to 3,29 V
At picture number 5 called "Powerboard" there is a change. With 4 and 5 (the ribbons at the tcon) connected the voltage at pin 2 (the black one) is near 0, but if I disconnect them, the voltage goes to 8,61 V
There a several other changes but its only a few percent. Do you need me to list them...Last edited by Spu; 08-30-2017, 01:44 PM.

Thank you for your response.
When I unplug 1 at at a time:
1) Nothing happens
2) Sound changes a bit, gets a bit louder
3) Sound changes a bit, gets a bit louder
4) The noise is gets very low
5) The noise is gets very low
6) The noise goes away...

LG 65uf860 Black screen, no sound. Gets an error code from the power board
Hello
I have an LG 65uf860v
One morning the screen turned green/purple and then black. Before that everything was normal.
There is no backlight and no sound. If I use a flashlight I can see the screen flickering when turned on.
The t-con board makes a “high frequency sound” but not very loud.
Also on the powerboard the diode LD701 is flashing 5 times. several times. Cant find the meaning of this.
At the powerboard I get the following. All the numbers are steady.
At standby:
11 and 12 is 3,51 V...
