I have a Vizio 60" plasma it won't turn on, when I press the power botton I hear a single click and no picture or sound but the front Vizio logo light is on. Then I pressed the power button again and this time no click sound but the front logo is is still on. I unplugged it and replugged it in and pressed the power button the single click sound again, pressed it a second time and no click sound. I opened the back to check the fuses they look OK.
