(Gate Low), alongside other standard levels like 1.7V, 3.1V, and 6V. Flexible Design

Often caused by a break in the gate signal passing through the COF.

If you tell me the (often found on a white sticker on the back of the panel) or the TV model , I might be able to help you verify if this is the correct COF for your issue. If you'd like, I can also provide tips on: ACF tape selection Bonding pressure settings

Positive voltage for turning on pixels. STV (Start Vertical): Start pulse for the gate scanning. CPV / CLK: Clock signals for timing the scanning. VCC: Power Supply. nt61219hc6021a cof datasheet exclusive

Triggered by a loss of digital power (VDD) or clock signals feeding into a specific segment of chained COF modules.

is an internal break in the flexible film, leading to a loss of or VGL at the side COF. The Fix: Technicians often use a COF BoardView to identify the exact pin location on the COF.

Typically negative voltage for turning off pixels. (Gate Low), alongside other standard levels like 1
