If the TV shows no signs of life, start at the primary side.

Cleans incoming AC mains voltage and converts it to high-voltage DC. 17ips72 schematic

Power supplies store lethal amounts of energy. Always practice proper safety measures. If the TV shows no signs of life, start at the primary side

Use an isolation transformer when measuring live voltages with an oscilloscope on the primary side. 17ips72 schematic

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

before performing any continuity or resistance checks.
