Vestel 17ips12 Schematic
Technical Overview: Vestel 17IPS12 Power Supply Unit (PSU)
Introduction
The Vestel 17IPS12 is a widely used switch-mode power supply (SMPS) board manufactured by Vestel, a major OEM (Original Equipment Manufacturer) for television brands. This board is commonly found in various rebranded LED and LCD televisions, including models from Hitachi, JVC, Toshiba, Telefunken, and Vestel’s own brand.
3. Measuring Correct Voltages
You can measure critical test points: PFC output (should be ~380V DC), 5VSB, and VCC for the PWM ICs. The schematic lists expected voltages. vestel 17ips12 schematic
The 17IPS12 operates as a Switch Mode Power Supply (SMPS), designed to convert high-voltage AC mains power into stable low-voltage DC rails. The primary stages of the circuit include: Technical Overview: Vestel 17IPS12 Power Supply Unit (PSU)

- Remove R501 to isolate the Mainboard connector from the Driver IC.
- Solder the "Add-On Module" PWM output directly to the Driver IC side of the R501 pad.
- Power the module from the 3.3V Standby rail (Pin 1 of CN1 usually provides this).
