Vestel 17IPS62 is a widely used Power Supply Unit (PSU) found in 32-inch to 55-inch LED TVs from brands like JVC, Finlux, Toshiba, and Techwood. Its schematic reveals a compact, cost-effective design that combines the primary power conversion and the LED backlight driver on a single board. Key Technical Specifications
Vestel boards are heavily prone to capacitor degradation. Visually inspect the secondary filtering capacitors for domed tops or leaking electrolyte. Even if they look physically intact, test their Equivalent Series Resistance (ESR) with an ESR meter.
Understanding the differences between the -R2 and -R4 versions is crucial for accurate repair.
This board is used across many brands, including Toshiba (32L3753DB, 32W1333DB), Hitachi (32HB6J41U, 32HB4T62), JVC (LT-32VF52K), Finlux (32-FHA-5160, 32-FFA-5615), Bush (DLED43FHDS), Panasonic (TX-32DW334), and many store-brand models like Selecline, AYA, and Hyundai. 17ips62 schematic diagram
The schematic diagram reveals a straightforward but effective power supply architecture. While official schematics can be challenging to source (as discussed later), the technical function relies on a few key integrated circuits.
If replacing Schottky diodes or MOSFETs, choose components from reputable manufacturers with identical or slightly higher voltage and current ratings to prevent premature recurring failures.

Often, a surge blows the primary MOSFET (Q100 or Q101) and the Controller IC (U100) together. B. TV Turns On, Then Off / Blinking LED
Before diving into the schematic, it is critical to understand what a "17IPS62" board typically contains:
Confirmed reference: Sams 894-3 is the correct folder. This board is used across many brands, including
and uses line filters (LF2, LF4) and transformers (TR1, TR2) for power distribution. Control Signals : Includes dedicated pins for Power ON/OFF Brightness Adjustment (PWM), and Overvoltage Protection Common Faults & Repair Guide
: Common versions use an integrated PWM controller (such as the SG6742HR or similar variants) to drive the main MOSFET (e.g., FQPF8N60C). 2. Output Specifications
