    Magnavox 19MF338B voltage from PS but no pic or sound? :{

    Hey All,
    I am working on Magnavox 19MF338B this week. I plugged it in, press the power button it gets the green light on the power button, but I dont hear any relay, i have no picture, no backlight and no sound. I tried to hook up a source and click through inputs with the volume up, but nothing. I opened it up and check voltage from the power supply, seems my 5v and 12v voltages are good so I dont know what is up here. Also another note. when you hit the power button and green light comes on for the set, no matter what you do on the power button or the remote, you cannot get it to go off, the light wont turn off at all unless you unplug. Any help would be great, thanks!
