Lx1692 Protection Pin ((exclusive)) -

Desolder the small capacitor (usually labeled C_PRO or similar) connected to Pin 11. Measure its resistance. A healthy capacitor should show open circuit (infinite ohms) after an initial spike. If you see a steady resistance under 100k ohms, replace the capacitor.

Once the startup window closes, the protection circuitry becomes highly sensitive. If an anomaly causes the voltage on the PROT pin to rise above its internal threshold (typically around 1.3V to 2.0V, depending on the exact chip datasheet revision), the IC recognizes a critical fault. 3. Latch-Off Mode lx1692 protection pin

The "LX1692 protection pin" refers to the chip's integrated safety network, which uses the ISNS, OV_SNS, and OC_SNS pins to monitor and protect the CCFL backlight in LCD displays. While disabling protection can be a useful diagnostic tool, the ultimate solution is to find the root cause, replace faulty components, and ensure the circuit operates safely within its limits.

What do you get on the supply and enable pins? Are you working with a TV or a monitor board ? Desolder the small capacitor (usually labeled C_PRO or

For detailed electrical specifications and pinout diagrams, you can refer to the LX1692 Datasheet at Alldatasheet or Datasheet.HK .

The irony of protection circuits is that they protect the hardware, but they often become the most frequent cause of "black screen" symptoms. Technicians frequently encounter the following scenario:

If your LX1692-based inverter shuts down unexpectedly: If you see a steady resistance under 100k

Detects if a lamp is disconnected or broken.
