My tv won't power up. No red led power light,sound, nothing. I replaced the resistor talked about on other posts about two years ago. I just replaced the flyback transformer on a recomendation from an on line tech (Waste of 20 bucks). There is a chirping noise coming from somewhere on the board, but I can't tell where. Please help! The wife and kids are driving me nuts without their tv set! Thanks, Jon
