Vestel 17ips62 Schematic [2026 Release]
The Vestel 17IPS62 is a widely used Switch-Mode Power Supply (SMPS) board found in various LED TV brands, including Toshiba, JVC, and Hitachi. The schematic for this board, commonly available in revisions like R2 and R4, details a complex network of components designed to convert AC mains power into regulated DC voltages for the TV's mainboard and backlight. Key Technical Specifications
The 17IPS62 board manages multiple voltage rails essential for TV operation:
Input Stage: Features line filters (LF2, LF4) and bridge rectifiers to handle raw AC input, producing a high-voltage DC rail (approximately +400V). vestel 17ips62 schematic
Output Rails: Typically provides stable 12V and 24V outputs. Some variants also output 5V or 35V depending on the specific monitor requirements.
Main Controllers: Often utilizes integrated circuits such as the FAN6300 (PWM controller) and MAP3249 (LED driver) to regulate power delivery. Common Failure Points and Troubleshooting The Vestel 17IPS62 is a widely used Switch-Mode

2. Dead TNY267 (IC2) – No 5VSB
- Symptom: Dead as a doornail. Fuse F1 intact, but no 5VSB.
- Repair: Replace IC2 and also replace the small electrolytic capacitor connected to its BP (bypass) pin – usually C10 (22µF/50V). Also check optocoupler IC5.
- Schematic note: Check resistor R17 on the drain pin of IC2 – often goes open circuit if the IC shorted.
Where to find the schematic:
- ElektroTanya (elektrotanya.com): The most reliable source. Search for "Vestel 17IPS62" or "17IPS62 schematic". Look for the PDF named "Vestel 17IPS62-Power Supply Schematics.pdf".
- Badcaps.net Forums: The repair community here often posts annotated schematics and voltage maps for this specific board.
- Eserviceinfo.com: Another good repository for TV chassis manuals. Look for the "Vestel 17MB95" chassis manual – it includes the 17IPS62 section.
- AliExpress & eBay Listings: Some sellers of repair kits include a download link to the schematic. Check the product descriptions for "free schematic with purchase".
Pro Tip: If you search for "Vestel 17IPS62 schematic" on Google Images, you will often find partial circuit fragments posted on forums. Use these to cross-reference component values (e.g., resistor R123, capacitor C28). Symptom: Dead as a doornail

7. Alternatives to Repairing the 17IPS62
If your board is severely burned (e.g., lightning strike, fire damage), repair might not be cost-effective.
- Universal Power Supply (SUP series): You can buy a universal LED TV power supply (e.g., "SUP-32" or "ZHL-32") for ~$15. You will need to map the pinout: 5VSB, PS-ON, 12V, 24V, GND. This requires modifying wiring, but it works.
- Buy a Used/Refurbished 17IPS62: Search eBay or Aliexpress for "Vestel 17IPS62 Rev 1.0 / Rev 2.0 / Rev 3.0". Pay attention to the revision number – a Rev 2.0 might have a different 24V connector than a Rev 3.0.
- Donor Board: Many Vestel TVs from 2011-2016 use this PSU. Check models like Toshiba 32L22, Finlux 32F6030-T, Hitachi 32HK200 – they all contain the 17IPS62.
Introduction
If you are reading this, you are likely staring at a dead TV. The screen won’t turn on, the standby LED is off, or you hear a faint clicking sound. In the world of modern LCD/LED television repair, few names appear as frequently as Vestel. This Turkish OEM (Original Equipment Manufacturer) produces motherboards and power supplies for dozens of brands, including Bush, Hitachi, JVC, Toshiba, Telefunken, Finlux, and Polaroid.
At the heart of many 24-inch to 43-inch models lies the Vestel 17IPS62 power supply board. Without the correct Vestel 17IPS62 schematic, diagnosing a fault on this board is like navigating a maze blindfolded.
This article provides a comprehensive breakdown of the 17IPS62 schematic, common faults, voltage rail analysis, and step-by-step repair strategies.
A. PFC Controller (IC1)
- Common Chip: FAN7930C or SG6961.
- Function: Boosts the voltage from the main capacitor to 390V-400V.
- Key Pins:
- Pin 8 (VCC): Requires ~15V to start.
- Pin 7 (OUT): Drives the PFC MOSFET Gate.
- Common Fault: If the VCC pin voltage is low or fluctuating, the PFC will not start, resulting in a non-start or clicking sound.
