Cordial greetings colleagues. I have this apparent double image flaw. I attached a video for you to see. In this fault I focus on checking the tcom, checking all the voltages at their respective measurement points that the same tcom indicates, finding all their correct voltages. Then I proceeded to remove a Flex from the Asia Tcom panel, to see which side it is that the fault is tested. I went on to turn on without one of the flexes, and he didn't give me a picture. It is supposed to have given an image in the middle of the panel, which did not happen even when disconnecting the other Flex, it only gave me lighting. And audio. I proceeded to place the Flex again and turn on the TV and continue with the same fault. Looking at the image I saw something strange that the image has in the form of four picture frames. And I wondered if it could be a fire what problem. Looking forward to your collaboration.

Friend to these TVs can not work with the method of removing a tape to locate the part of the damaged panel, because the tcon has a protection circuit that if it does not detect the complete connection of the display turns off the dc-dc converter. According to your comment it is clear that you have a problem on the screen and to solve you must eliminate the clock and start signals that go to the damaged cof chip. For this you must locate the test points belonging to these signals, they are located above the left connector of the tcon. You should cover these points with a press and test if it corrects the defect, if not do it on the other side. Do these tests and comment to continue helping. Greetings and luck

Colleague Franki could not see the points that you indicate to me clock and start of any of both sides of the Flex of the tcom, but I decided to cover with tape one of the Flex on the right side from right to left from pin 16 to 21 .
I throw the following result, covering pins 16 and 17 I no longer had a double image, but if the left side of the screen turns dark but the image is appreciated although dark.
Your collaboration is very acute, but I don't know if that part can be corrected.
Cordial appreciation for your collaboration.

Friend that is because you are covering 2 different signals, you must cover ckv and ckvb of the same signal, here I explain to a colleague how to do, read here until the end https://www.yoreparo.com/en/tv/preguntas/ 6148688 / samsung-un46f6800-screen-gray. I hope it helps you. Comment results. Greetings and luck

Greetings again, Franki.
I tell you that I could not or do not know how to upload photos is that I use my cell phone. And I don't know if it can't be done from the cell phone.
I could not find the two correct clock and start signals of the damaged cof. Because in the Flex of the tcom they are not marked, or because they are very small letters I cannot see them. But as we achieved thanks to your contribution partially correct the fault, and my client is desperate for his TV, in the image menu I put it dynamic, and without saving energy, to keep the image clearer. Thus the darkness of the image is less appreciated.

Ok friend, read the post that I indicated to you so that you have a more exact reference of the fault and it will serve you for future repairs since these TV models are falling by quantities. Greetings and luck

Colleague Francisco, thank you for your collaboration if the panel is effectively damaged one of the cof.
I checked with the contribution made by colleague Franki. And he gave me a possible solution.
