2 Should I try Power supply board or main board on led tv?
LED tv, started with speakers, turn on tv get normal sound for about 3 min then an unbearably loud static noise. About a month later the screen went black, turn the tv on good picture for a couple min then black. A week later doesnt turn on at all and just slowly blinks power light. I seriously doubteach component just failed back to back. What do ya think? Power supply board or main board? Didnt notice any bad capacitors...its a 600$ tv might as well try a 40$ board...
Esta é uma boa pergunta?

@jorricha any pattern to this " just slowly blinks power light"? What model is your Vizio?

@oldturkey03
Vizio m471i-a2
As far as "blink" if i plug it in without pressing the power button the white power light slowly goes from off to dim to fully lit to dim to off over & over in about a 5 second cycle
Thanks

Just some more info...When the loud static noise started at the beginning of all of this, i hooked up a soundbar to audio out and the sound came through there as well.

@jorricha any chance you can take a couple of good images of your boards and post those with your question? Use this guide Adicionar imagens a uma pergunta já existente for that. It'll allow us to see what you see.

@oldturkey03 Hope that helps, looking @ it again the tops of the 2 on the main board "2n 470 25a" seem to be protruding a little. The tops of all the caps on the power supply are flat.
