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...
ANSWERS:
