The 17IPS62 is not just a power supply; it is a "3-in-1" solution. Unlike older "triple-decker" boards where the inverter transformers sat atop the PSU, this board utilizes a low-profile layout designed for slimline LED/LCD televisions (often Vestel-chassis units used in brands like Hitachi, Telefunken, JVC, and Bush).
The Vestel 17IPS62 schematic reveals a sophisticated design, comprising various components such as:
If your television suddenly refuses to turn on, clicks repeatedly, or displays a blinking standby light, there is a very high probability that a Vestel-manufactured power supply board is at fault. Vestel is one of the largest original equipment manufacturers (OEMs) in the world, producing TVs for household brands like Toshiba, Hitachi, JVC, Sharp, Bush, and Techwood. vestel 17ips62 schematic new

Vestel 17IPS62 is a commonly used power supply unit (PSU) found in many LED TVs. Schematic documents for this board, particularly versions The 17IPS62 is not just a power supply;
Based on the schematic topology typical of the IPS62 series, the board relies on a trifecta of specific IC controllers.
Replace all three UF5402 diodes in parallel using components from the same batch to ensure matched characteristics. If the MOSFET is shorted, the driver IC has likely sustained damage as well and should be replaced. After replacing these components, check the snubber circuit diodes (D36 and D37) for signs of overheating. This repair is so common that many technicians consider it the "signature" failure mode of the 17IPS62. Vestel is one of the largest original equipment
