Vestel 17ips12 Schematic Better -

Includes circuitry for overvoltage protection, brightness adjustment (PWM), and power on/off control. Key Components & Voltages Commonly uses the as the PWM controller for the switching stage. Output Diodes: STPS20H100CFP

is a complex board that combines several key power stages into one unit:

Monitors backlight voltage and current. 3. Common Failures and Troubleshooting Steps

Inspect capacitors (e.g., C100, C110) for bulging. They often fail, causing unstable voltage. vestel 17ips12 schematic

Look for burned or high-value resistors around the MOSFET. 5. Summary Table of 17IPS12 Voltage Checkpoints Checkpoint Typical Voltage Component to Check Primary 300-340V DC Main Capacitor (400V) Standby C900 Series, Regulator Secondary 12V / 24V DC Diodes (STPS20H100) Backlight 40V - 100V+ DC Connector CN4/CN6

To verify the board's health, use a multimeter to check these standard outputs:

), filtering, rectification, and the main switching transistor. Look for burned or high-value resistors around the MOSFET

: The transformer provides multiple secondary windings to produce: : Used for general system logic and audio. : Primarily for the backlight inverter or driver stage. Standby Voltage (+5V)

The 17IPS12 acts as a power supply (switching 220V AC to required DC voltages) and an LED driver (supplying high voltage to the screen backlight). It is commonly found in 32-inch to 40-inch LED TVs. Input Voltage: 100-240V AC ~ 50/60Hz

Using the , you can locate common failure points. A. No Power / Dead TV including models from Hitachi

Vestel 17IPS12 Schematic: Troubleshooting and Repair Guide for LED TV Power Supply Boards

The 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.

Utilizes a switching controller (often a FAN6300 ) and transformers to generate the main +12V and +24V rails.
