Vestel 17IPS62 is a widely used Switch Mode Power Supply (SMPS) board found in various LED and LCD televisions. It is primarily responsible for converting AC mains power into the specific DC voltages required for the TV's mainboard and LED backlight system. Key Technical Specifications
The circuit design typically includes several critical power stages and components: Voltage Rails
: The board generally manages multiple inputs and outputs, including (PFC stage), Main Components
: Includes line filters (LF2, LF4), transformers (TR1, TR2), and bridge diodes to regulate current flow. Control Signals : Features dedicated pins for functions like STBY_ON/OFF (standby), BKL_ON/OFF (backlight control), and (dimming). Common Issues and Repair Tips
According to technician forums and service notes, several recurring faults are associated with this board: Blown Diodes
: A frequent design flaw involves three diodes in parallel that may overheat and short-circuit. Experts recommend replacing all three with ones from the same batch to ensure balanced current sharing. Low Voltage Output
: If the 12V rail cannot stabilize or pulses, it often indicates an issue with the oscillator driving the MOSFET or a short-circuited capacitor.
: Check the primary fuse, varistor, and bridge diodes for shorts if the TV fails to turn on entirely. Schematic Downloads

Vestel 17IPS62 is a widely used power supply unit (PSU) found in TV brands like JVC, Finlux, and Toshiba. When reading the schematic, focus on the primary high-voltage stage, the secondary output rails (12V and 24V), and the LED driver circuit. 1. Key Voltage Checkpoints
A healthy board should show stable outputs on the secondary side: : Check across capacitor : Check across capacitor Primary Filter : Should show approximately 310V to 400V DC across the main reservoir capacitor when active. Driver IC (U1/BM1) URL: elektroda
: Pin 8 should typically show high voltage (310V-400V) which provides initial power for oscillations. 2. Critical Components in the Schematic : 3.15A Wickman style; check for continuity first. Rectifier Diodes
diodes (D30, D31, D32, D33); these often fail and can be upgraded to for better reliability. Chopper MOSFET (Q1) : Common parts include MMD70R600P IPD70R600P . A short here usually blows the main fuse. LED Driver (U5) : If you have sound but no image, check , and diode 3. Troubleshooting Common Faults Dead (No Power) : Check for a shorted
. If the fuse is blown, always check the four rectifier diodes before replacing it. Pulsing Voltage
: If the 12V output is pulsing and cannot stabilize, the oscillator IC or its auxiliary power circuit may be failing. No Backlight (Sound OK)
: Often caused by a failure in the LED driver section or a faulty . Also check Important Variant Warning
There are many versions of the 17IPS62 (e.g., R2, R4). While they look similar, they have different LED output current specifications and connector pinouts. Always match the
code found near the barcode or QR code when sourcing a replacement.
While some IPS boards use the main LLC chip for everything, the 17IPS62 often retains a discrete Standby chip (typically a LD7536 or TEA1733).
