An integrated circuit (IC) modulates a high-voltage MOSFET to rapidly switch the high-voltage DC across the primary winding of the main flyback transformer (TR1/TR2). 2. The Secondary (Cold) Side Circuit

LED Backlight Driver IssuesIf the TV has sound but no image (the "flashlight test" reveals a faint image on the screen), the LED driver section of the 17IPS62 may have failed. This is often caused by a faulty boost MOSFET or an open-circuit resistor in the backlight return path. Schematic Breakdown and Voltage Rail Testing vestel 17ips62 schematic

The 17IPS62 board has two main sections separated by a thick white line: An integrated circuit (IC) modulates a high-voltage MOSFET

Steps down the high-voltage high-frequency switching DC into lower voltages. This is often caused by a faulty boost

Power surges or thermal wear can cause the primary switching transistor or its controller IC to blow.

) or secondary side diodes often fail or short-circuit. Upgrading to is a common repair practice. Chopper MOSFET : The main power transistor (e.g., MMD70R600P IPD70R600P ) can fail, usually blowing the main 3.15A fuse Board Material : The board is typically made of
