Detects and shuts down the controller in the event of arcing on the transformer secondary side.
To give you a , could you clarify:
Only bypass the protection pin to confirm that no other major faults exist (like a shorted MOSFET). If the backlight stays on after bypassing but looks normal, you likely have a false trigger from a leaky capacitor, not a real fault. lx1692 protection pin
: The IC includes safety circuits that monitor the transformer secondary voltage. If a lamp fails or the voltage spikes, the protection circuit triggers a shutdown to prevent damage. Protection Pin Number : For the LX1692, the Detects and shuts down the controller in the

When a TV powers on for a second and then the backlight clicks off, the LX1692 has done its job. The technician is often tempted to "force" the TV on. In the repair community, there is a known trick involving the Protection Pin:
