Illustrated PDF guide on cutting the CKV and CKVB lines of an LCD panel, with NC indicating the lines are left disconnected, in a redacted edition of about 700 KB. CKV and CKVB are gate driver clock signals, and isolating a shorted section is a known workaround for half-screen, line or ghosting faults on TV panels. Technicians use it to locate the traces on the panel or T-con board before cutting. Measure the lines first to confirm a short, and check that your panel matches the shown layout, because the cut is permanent.
