CKV Short Killer

[kevin_allein]

Hi, recently I found a lot of videos on YouTube regarding CKV Short Killer. All of those Videos seem to be from Asia (e.g. in Hindi). I could not find a single English Video. Translation on YouTube on those videos does not work well, so it is hard to understand details.
Basically it seems to address the frequent problems of LCD panels, when CKV and CKVB lines have some short and the only fix is to cut those lines or use tape on the ribbon cable to the secondary scalar board of the panel.
Does anyone have any experience with that ?

dont trust Hindi Videos at all... they generate fault on TV and then they play that they discover the issue. 99% do this fake.

CKV come direct from MB via LVDS.. if there short need to inspect MB , as yours other threat.. i would inspect the PWM on MB. spark which u faced before a serious issue kan kill PWM easily.

Well the disconnect all boards and inject the high current only into the panel to burn through the short. That does not sound so wrong, does it ?

Sounds risky but if someone is sure the problem is inside the panel, guess there's not much to lose, even if it doesn't work.

this is rubbish talking. sorry.. .. same to yours last answer from Italy on other threat... yours T-CON are ingratiated at MB not at panel-... the work and testing should be at T-CON circuit at MB always
