my toshiba flat screen tv is stuck in ant/cab mode and sounds like it's turning on and off. the green power light stays on, but the white toshiba display on the center front bottom flashes on and off with each click sound. i can't access menu and it won't let me change anything on the imput screen. i tried pressing the power button for 5-10 seconds with no luck. is there anything else i can do to reset the tv?
