Those are lines that go through the sides of the COF normally. One single and next joined double again single. You may have to study videos and articles and practice it on panels. Guidance will be limited.

Thanks!

Great Job... I too am alway wondering about CKV Lines.... How do you Identify which traces are CKV line... I have watch some videos on YouTube and saw wher they use a Short killer to repair shorted CKV lines. I just want to know how to identify them.

Great ! Please dont bag it all share it with your techie friends who always stand by you.
I presume SM4186 is a gamma IC. Now this TV being a Samsung, the IC has among other principal functions; to monitor abnormal voltages and currents in that region of the TV set up. So once a short in the panel is sensed by SM4186, the IC, being a loyal servant, dutifuly triggers a safe mode that shuts down TV. SM4186 then sits and waits until the culprit CKV shorted lines are eliminated by the cut of a surgeons razor. Only then does TV functionality resumes using an extra path, so I think. Like in humans. a bad kidney is removed and one remains for someones continued survival.
Please techies lets share skills and views. No one amongst you is suggesting about the use of small jumper wires when rejoining ckv lines and joining all the lower pads of the linking capacitors so as to alternatively short them, or even just making it known that the word 'date' was supposed to be 'data'. I just love TV repair stuff.

Cutting was done and bypass was by shorting the glass end tracks that went into the panel. Many thanks, dear Imoudu!

It should be very high for a normally working panel.

The CKV lines to the panel were cut and joined together at the glass side. Many thanks for your expert and analytical comments, dear Albert!

To identify signal lines and ckv is a bit difficult for me,well good repair you have done,it seems to be cutting modifications rather than bypass though.
