: Measured at the secondary diodes (right side of the board), this powers the motherboard. VLED / Backlight Supply : Standby/Unloaded : Typically measures around 30V–35V .
Among their widely used components, the power supply unit (PSU) is incredibly common in 32-inch to 43-inch LED TVs. When this board fails, having the Vestel 17IPS62 schematic (new version) is the single most important asset for a successful bench repair.
The Vestel 17IPS62 is one of the most widely used switch-mode power supply (SMPS) boards in the television manufacturing industry. Found inside millions of budget-to-mid-range LED TVs under brand names like Toshiba, Hitachi, JVC, Techwood, Finlux, and Telefunken, this board is a frequent sight on repair benches worldwide. vestel 17ips62 schematic new
Measure the voltage across D23-D25. If these diodes are shorted, replace them. Also check the current-sensing resistor on the primary side, as it may be open-circuit, preventing the PWM controller from regulating properly.
Converts AC voltage into high-voltage DC (around 320V DC in 230V regions). : Measured at the secondary diodes (right side
Avoid old, low-resolution images from Pinterest or random Russian forums. Here are the current best sources as of 2024/2025:
: Filtering capacitors ( C57 , C38 , C39 ) can bulge or lose ESR, leading to unstable 12V or 24V rails and flickering backlights. When this board fails, having the Vestel 17IPS62
