17ips62 Schematic Diagram [hot] [2024]
The Vestel 17IPS62 is a widely used Power Supply Unit (PSU) found in various budget and mid-range LED TVs, including brands like JVC, Toshiba, Techwood, and Telefunken. It is a combined power supply and LED backlight driver board. Schematic Overview
Protection Circuits: Includes overvoltage protection and control signals for power management (on/off) and backlight brightness adjustment. Available Schematic Resources 17ips62 schematic diagram
- 5VSB (Standby): Supplies the microcontroller (MCU).
- 12V: Supplies the audio amplifier and backlight inverter input.
- 3.3V: Regulated from 5V via an LDO (e.g., AMS1117-3.3) for the panel logic.
Step 5: Request a Custom Tracing or Redraw (If you cannot find the original)
If the original is too degraded or unavailable, you can: The Vestel 17IPS62 is a widely used Power
- No power: F1 blown (schematic coordinate B2). Cause: overvoltage or failed capacitor C2 (input filter).
- Vertical lines on screen: Broken trace between TCON IC pin 47 (
RSDS_OUT3) and CN2 pin 22. Use continuity mode on the schematic layout. - Flickering image: Fluctuating VCOM due to failed op-amp U4 (LM324). Replace per the schematic.
