No Franki what a shame is that the image that I uploaded was not when looking for the pins that I mentioned and when deleting delete image was the question but I commented that I tape four pins from 16 to 19 of the left flex only those four and the TV I is giving full picture what I notice is that even the right ic 81222 heats up more than the left one

The other is that the pins that tape comes from the left ic 81222

That image if it's the plate I'm working on, the other one I thought was the same and I noticed that it changed

I hope you have understood everything explained above. Now in this tcon, it works in the same way as the other, even its protection is more sensitive, near the left connector there are 9 test points 5 above and 4 below, a little to the right has who is each screen printed, if already You determined that the left side is that of the fault, do the following, you will just cover the signals wide open, that is ckv1 and ckvb1, if you cut video uncover these and covers ckv2 and ckvb2 and so on. I say cover no cuts since they are in parallel with those that enter the other connector ....

... do it directly on the tape with a piece of tape or thin paper. If you want start with ckv2 and ckvb2, they are the ones that fail the most. You must give it time to test until you are sure that it solved the problem. When you are sure of the affected pair you can cut “on the tape” at the end of the tcon connector with exactly the 2 affected pins. I await comment. regards

Franki as I do to upload another image and show you the pins I found on this card. I told him to cover pin 16 17 where he said ckv2 and he returned the image but it went out after a long time like two hours the ic 81222 on the right side gets very hot as the ckv2 tape I must also cover the ckvb2

Note that 16 and 17 belong to the same signal, the clock pulses is a positive and a negative one ckv1 and ckvb1 or ckv2 and ckvb2, etc. if you remove one you have to remove the other

So if you covered the ckv2 I must cover the ckvb2 also did not answer me if you know how to upload another image to this post

Also you can not cover a "1" and a "2" at the same time. Here they explain how to upload a photo https://www.yoreparo.com/comunidad/preguntas/960117/subir-foto. It doesn't work for me because I connect from my mobile phone but maybe you have more luck jjj. regards

Amigo Franki told him to cover track 16 and 17 which is from ckv2 counting from left to right and track 21 and 22 ckvb2 counting from right to left this is from the left flex has been working for three hours without any problem thank you for your collaboration

Ok, congratulations, I hope it serves as a reference for other TVs, the solution is the same for any brand, even in this one it is a bit more difficult, any doubt you tell me. Greetings and luck

Franki sorry to write again but it turns out that the client put the TV to work and went out of image again cover all the lines that the stvp told me the ckv1 ckvb1 ckv2 ckvb2 ckv3 ckvb3 and after two hours he returns without image and the integrated on the right side 81222 gets very hot

Greetings friend read in this post where I explain to a colleague about a defect similar to yours, then tell me what you have done here to help you. https://www.yoreparo.com/es/tv/preguntas/6148688/samsung-un46f6800-pantalla-gris

The curious thing is that I have all the clock signals indicated by the stvp and the ckv and ckvb, both the positive and the negative, I want to ask you something that makes me curious the main microprocessor has something to do with this fault since not heatsink that she brings heats up so much that I can't stand it with the full fingers

Thanks, I understand that I can't cover them all at once if not in pairs is correct or wrong

Exactly, first those of a connector and if you continue turning off those of the other. From what you tell me about the micro, I will tell you that they work very hot, the first time I touched one I was amazed, but then I uncovered a new TV that came by split screen and also the micro worked hot, I concluded that they work like this, do not worry therefore.

Ok I have the last doubt you mention cover the ckv and ckvb that are responsible for the clock signal also covered the stvp that is the signal start or only the ckav and ckvb

The stvp is the start signal, it is unique on each side, that is, the right side cof chips are fed with the same signal, in parallel, in the same way on the other side; sometimes it must also be removed, when after to repair the fault there is a defect like a light white curtain, but I always leave it last in case it is not necessary

Franki would like to help me to know what the routes are since, as I see a non-identified screenprint, the clue is

He covered but the fault persists then I think I'm covering the track that is not

In the second photo you sent Note that there are 2 rows of test points, the one below belongs to that screenprint you see (clvb3, ckvb1, ckv2, fb-l) in that order. The top row that is enclosed between lines belongs to screenprint B, first photo in that same order (stvp, ckvb2, ckv3 and ckv1). When I say the same order is that the rightmost point belongs to the rightmost signal and so on. regards

Franki what if you notice in the first picture I send there are two resistant 10 ohm track and there is the stvp ckvb2 and successively my question is in the rn2 resistor there are four ways the stvp signal comes in the first two and the ckvb2 signal in the next two or is it alone or all these four signaller comes in a single resistor

Franki Lobaina

In those resistances you should not do the job, there is only the screenprint B that belongs to the test points of the second photo line above. Answer if you understood

In the second photo I only have the ckvb3 ckvb1 ckv2 and fbl and inside the enclosed are four welding points and on the outside there are another four points
