Re: LG 43UK6200PLA - yellowish picture
There is probably more to the solution than what I did. I'm going to leave it as is and maybe in the future try again.

Re: LG 43UK6200PLA - yellowish picture
The other side didn't flicker. I will probably leave it as is for now. When I block pins similarly to videos you shared (10-12 pins at once) the picture would be solid but discolored....

Changing the brightness didn't do anything....

What is the drilling method? I am probably going to leave it as is for now. It is watchable and if you don't look for flickering it's not that noticeable....

Re: LG 43UK6200PLA - yellowish picture
I found this video: [url]https://www.youtube.com/watch?v=ESGYMioW4yQ[/url]
Does anyone have any idea what is he doing? I watched it a few times but don't understand what does he check when probing left and right side at the same time. Also what should the voltages be at those resistors?Re: LG 43UK6200PLA - yellowish pictu...k when probing

Re: LG 43UK6200PLA - yellowish picture
When I did the half screen test it did flicker on the faulty side. Energy saving was on and when I switched it off it only brightened the screen a bit and nothing else. It was tested without any cables just power.

Re: LG 43UK6200PLA - yellowish picture
After blocking pins 9 and 11 I get a normal picture without lines, but there is slight flickering. Also I noticed if I block pin 12 (along side 9 and 11) the colors change between normal and yellowish like at the beginning. Other pins don't seem to have any effect on colors or flickering. I have no idea what to do now.

Re: LG 43UK6200PLA - yellowish picture
My bad, I worded that a bit badly. I meant that when I connect one cable only I get half screen normal white and when I connect only second cable it doesn't work correctly. The cables themself are ok....

Re: LG 43UK6200PLA - yellowish picture
I did that and it looks like pin 9 is the general problem. When I block only pin 9 the colors are fine but there are pruple vertical lines when screen is black and normal lines when there is picture. Also there is one black line that doesnt change....

LG 43UK6200PLA - yellowish picture
Hi everyone. I have LG 43UK6200PLA which stopped showing picture a while ago. The main board is model EAX67872805. It has sound and backlight. I tested the two ribbon cables on the tcon board and concluded that one of them is faulty. I taped pins 1-12 and now the picture is there and there are no glitchy lines. The problem is it switches from normal color to yellowish color repeatedly. In the attached photos the first one is normal color and the second one is changed color. Any suggestion is welcome.
Thank you all....
