Ground. A poor connection here can lead to excessive heating. 2. Switching Node (SW)
When debugging a faulty panel utilizing the INX IN518, place your digital multimeter in DC Voltage mode, ground the negative probe securely to the chassis or panel ground, and measure the following external surface-mount passive nodes surrounding the IC: Inx In518 Ic Pinout Diagram
: Produces the sub-zero VGL rail to keep the TFT gates firmly closed during their off-state cycle. Ground
Never substitute the IN518 with a general-purpose comparator like the LM339 . Although they may share similar footprints, the LM339 lacks the internal circuitry required for display timing and high-voltage generation. Switching Node (SW) When debugging a faulty panel
This pin connects to the external inductor and Schottky diode. It is a high-frequency node. If the backlight is flickering, this node is the first place to check with an oscilloscope. 3. Feedback and Enable (FB, EN)
: Bring the local T-CON fiberglass PCB section up to roughly 150∘C150 raised to the composed with power C
