Testimonial: "Took a part back panels looking at the circuit board power capacitors, plugged in TV to power outlet, and powered up normally."
It is detecting shorted circuits or power supply problem, need in-depth troubleshooting. Inspect the power supply module first for any sign of bad caps with domed tops, DC output voltage readings check.
