before performing any continuity or resistance checks.

If the voltage spikes briefly and drops, the board's protection circuit is likely triggering due to a failed LED strip inside the panel itself. Safe Troubleshooting Practices

Once you provide these details, I can offer a step-by-step diagnostic plan mapped to the board layout. YouTube·MrReeceyburger123 17IPS72 Repair

If the main fuse is intact but no standby voltage exists, the low-power standby IC might be defective. ⚡ Unstable or Pulsing Voltages

Uses a dedicated controller and MOSFET to pulse high frequency DC into the transformer.

If you want to troubleshoot a specific issue on your Vestel 17IPS72 power supply board: State the exact behavior of the TV.

Cleans incoming AC mains voltage and converts it to high-voltage DC.
