Vestel 17IPS62 is a widely used Power Supply Unit (PSU) found in 32" to 55" television models under various brand names like Finlux, Telefunken, and Hitachi. Its schematic revolves around a high-voltage primary stage and a secondary stage that provides 12V, 24V, and 35V rails to the mainboard and LED backlight. 1. Core Circuit Overview
The 17IPS62 schematic is divided into several functional blocks that manage power conversion and regulation: Primary Input & Rectification: The circuit uses line filters ( ) and bridge rectifiers (using
diodes) to convert AC input into a high-voltage DC bus, typically around Switching Section: A chopper control MOSFET (such as the MMD70R600P ) and a driver IC (commonly ) drive the main transformer ( ) to create secondary voltages. Secondary Voltage Rails: The board generates multiple low-voltage outputs, including for the mainboard and a higher rail for the backlight driver section. LED Driver Protection:
The LED circuit is designed to self-protect; it may only output ~30V when idle and will not ramp up to its required 66V–100V unless a proper load (functional LED strips) is detected. 2. Common Component Failures According to repair experts from Vestel PSU Repair Elektrotanya , the following components are most prone to failure: Component Category Specific Part Examples Common Symptoms Rectifier Diodes RL207, SR5100, SB5100 Blown fuse or dead short across reservoir capacitor. 3.15 Amp Wickman TV is completely dead; often blows due to a shorted bridge. Low voltage pulses or inability to stabilize at 12V. Backlight Diodes
Sound present but no picture; backlight flashes briefly then dies. 3. Repair & Replacement Tips Board Variants: Always match the specific number starting with

to prevent delamination. Use a soldering iron with flux and hold diode leads with pliers to protect internal junctions. Schematic Access: Full PDF schematics for revisions like are available on technical repositories such as Elektrotanya for a particular symptom, such as a no backlight
A standard 17IPS62 schematic is organized into five functional blocks. Below is a textual breakdown of each section, simulating what you would see on the actual diagram.
Using the schematic, find the VGH test point. If it is shorted to ground, look at C20-C23 on the diagram—one is likely shorted. Remove them one by one while monitoring the resistance.

The 17IPS62 schematic diagram is a technical blueprint for a power supply unit (PSU) manufactured by Vestel, a major producer of electronics for brands like JVC, Finlux, and Hitachi. This Switch Mode Power Supply (SMPS) is designed to convert high-voltage AC input into stable DC voltages, typically 12V and 5V, required to run the mainboard and backlight of modern LED TVs.
Understanding the schematic is essential for technicians diagnosing "dead" units or flickering screens, as it maps out the complex network of transformers, rectifiers, and protection circuits that keep the TV running safely. Key Sections of the 17IPS62 Schematic
The 17IPS62 circuit is divided into several functional blocks that work in sequence to process power:
Input & EMI Filtering: Includes line filters (LF2, LF4) and fuses (FS1, FS2) to protect the board from power surges and prevent electrical noise from leaking back into the mains.
Primary Rectification: Converts AC input into high-voltage DC (around +400V). Key components here include the bridge rectifier and the main filter capacitor.
SMPS Converter Block: Centred around the FAN6300 controller IC (U1) and a MOSFET (Q13), this section "switches" the DC voltage at high frequencies through the TR1 and TR2 transformers to step it down.
Secondary Output Rails: Provides the low-voltage DC outputs. A typical 17IPS62 board produces 12V for the mainboard and a higher voltage (often 24V or more) for the LED backlight.
Standby & Feedback: Uses optocouplers and the TL431 regulator (U3) to monitor output levels and adjust the switching frequency, ensuring voltages remain stable even as the TV's power demand changes. Common Failures and Troubleshooting Tips
Technicians often use the schematic to track down recurring faults that cause the TV to shut down or fail to start: Vestel 17IPS62 Schematic Overview | PDF - Scribd
The Vestel 17IPS62 is a widely used Power Supply Unit (PSU) found in various budget and mid-range LED TVs, including brands like JVC, Toshiba, Techwood, and Telefunken. It is a combined power supply and LED backlight driver board. Schematic Overview
The board is divided into two primary sections separated by a "hot" and "cold" isolation barrier:
Primary (Hot Side): Handles the AC mains input, rectification, and high-voltage filtering. It typically converts 230V AC into a stable ~400V DC (PFC) or ~320V DC. Note: If you require the actual PDF file
Secondary (Cold Side): Provides low-voltage rails (usually 12V and 24V) to power the mainboard and the LED backlight strips. Key Components & Functions
PWM Controller: Often uses a FAN6300 or similar IC to manage the Switch Mode Power Supply (SMPS).
LED Driver: Features a boost converter (often utilizing a MAP3249 IC) to increase voltage for the LED backlights.
Safety Features: Includes a 3.15A fuse (FS1/FS2) at the AC input and various snubbers to protect against voltage spikes. Common Failures & Troubleshooting
No Power / Dead Set: Check the main fuse and bridge rectifier. If the fuse is blown, the MOSFET on the primary side is often shorted.
Sound but No Picture: This is usually a backlight failure. Check the voltage at the LED connector (CN6). If the boost converter isn't jumping from ~24V to a higher voltage (e.g., 60V–100V), the driver IC or a LED strip is likely faulty.
Standby Light Blinking: 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
