Vestel 17ips62 Schematic -
The Vestel 17IPS62 is one of the most widely used switch-mode power supply (SMPS) boards in the television industry. Manufactured by the Turkish electronics giant Vestel, this board is found inside millions of budget and mid-range LED TVs sold under various brand names, including Toshiba, Hitachi, JVC, Techwood, Finlux, Telefunken, and Polaroid.
Diodes on the 12V or 5V rails. These are notorious for shorting out on Vestel boards.

Below is a guide to understanding its schematic, common failure points, and troubleshooting steps.
Do you have a , and have you taken any voltage readings on the secondary connectors yet? Share public link The Vestel 17IPS62 is one of the most
The Schottky diodes on the secondary side handle high current and high thermal stress. Over time, one or more of these diodes fail short-circuit.
When analyzing the Vestel 17IPS62 schematic, you should locate specific test points and components to verify if the board is functioning. Section / Component Expected Schematic Measurement ~320V DC to 340V DC (across pins) Confirms AC rectification is functional. Secondary Diodes (Output) +12V DC / +24V DC (relative to cold ground) Main power supply rails for the mainboard. Standby Pin (Output Connector) +5V DC or +12V DC Powers the mainboard CPU when the TV is "off". BL_ON / STB_ON Pins 0V (Standby) →right arrow 3.3V–5V (Power On) These are notorious for shorting out on Vestel boards
If the standby light behaves normally and the TV responds to the remote but shows no image, the power supply's LED driver or the LEDs themselves have failed.
Transformers (TR1/TR2) reduce the voltage, followed by diodes (e.g., SB5100) and capacitors for rectification and filtering.
