Vestel 17ips62 Schematic New __link__ May 2026

Vestel 17IPS62 is a widely used power supply unit (PSU) found in TV brands like JVC, Finlux, and Toshiba. When reading the schematic, focus on the primary high-voltage stage, the secondary output rails (12V and 24V), and the LED driver circuit. 1. Key Voltage Checkpoints

  • Primary side: Includes the 325V DC rail and the 390V PFC rail. This side uses a "Hot Ground" (floating). Do not connect your oscilloscope ground clip to this side without an isolation transformer.
  • Secondary side: Includes 12V, 5V, and chassis ground (Cold ground). Safe to probe normally.

Conclusion

4. PFC (Power Factor Correction) Stage

  • IC: IC801 (Commonly an NCP1608 or FAN7930).
  • MOSFET: Q801 (Typically a 600V/11A FET like STP11NK60Z).
  • Diode: D807 (Ultrafast diode, e.g., STTH8R06).
  • Function: Boosts 325V to ~390V. Without PFC, the TV will not start.
