Protects against over-voltage spikes (e.g., lightning strikes).
The standby circuit is a low-power flyback converter. This section is active immediately upon plugging in the TV.

To help find the exact wiring configuration or component values for your specific board variant, let me know:
Measure the voltage at the LED output connector during power-on. If the voltage spikes up high and then drops back down to the 12V baseline, the circuit is working, but the LED strips inside the screen are defective. If the voltage never rises above 12V, the boost circuit on the board is dead. Step-by-Step Troubleshooting Guide Using the Schematic Protects against over-voltage spikes (e
This board handles high-voltage mains power. Only attempt repairs if you have the proper tools and experience to avoid fatal electrical shock.
The transformer outputs several low-voltage AC lines, which are rectified by Schottky diodes and smoothed by electrolytic capacitors to create the standard Vestel voltage rails: What is the printed on your board (e
In conclusion, the Vestel 17IPS12 schematic is a comprehensive and well-organized diagram that provides a detailed overview of the monitor's internal components and their connections. The schematic is an essential resource for technicians, engineers, and anyone interested in understanding the inner workings of the monitor. While there may be some minor errors or omissions, the schematic appears to be a high-quality document that is useful for repair, maintenance, design, and troubleshooting purposes.
