Often caused by failing electrolytic capacitors on the secondary rails (12V/24V) or a corrupt EEPROM on the mainboard communicating with this PSU. Useful Resources
The main connector between the power supply and main board contains several control signals. Based on user measurements:
The PWM IC requires a high-resistance startup pathway from the bulk capacitor to start oscillating. Check the high-value SMD resistors connected to the IC's VCC line; if they go open-circuit, the IC will never turn on. Symptom B: Blinking Standby Light / Clicking Sound 17ips62 schematic diagram
The formula for setting LED current is I = k / R_ISET , where k is a constant defined by the IC's datasheet. For 1W LEDs typically used in 32" panels, the recommended current is ~300-350mA. Factory settings often drive LEDs at 396-450mA, leading to premature failure.

If you're looking to repair or understand the "17ips62" display, focusing on general troubleshooting steps or panel-specific characteristics might be more feasible without access to a detailed schematic diagram.
Check the . If the PWM signal is stuck low, backlight stays off. Check the high-value SMD resistors connected to the
