17ips72 Schematic — Easy & Certified

Look for the or IR35215 controller. The schematic includes the sequencing: +3VS5 → VDDIO → VDDCR → VDD_SOC → VDDGFX.

The power supply may attempt to start but "pulse" without stabilizing at 12V. This is often linked to the oscillator driving the MOSFET not receiving continuous power. No Backlights: 17ips72 schematic

: Small Schottky diodes on the secondary side frequently fail (short circuit), causing the TV to stay in standby or click repeatedly [1]. Leaky Capacitors Look for the or IR35215 controller
