no audio or video?

For 3-4 days, I couldn't get TV to turn on. The power light would turn from red to blue, about 3 seconds later, the blue light would blink again..and nothing..black screen. After 6:30 PM, it would work fine. Now I can't get it to come on at all. The manual buttons or remote control don't work on it after I turn it on. I have to unplug it to get back to the red power lite. I have unhooked it from cable box, checked batteries, unplugged it overnight, changed plug-ins. Nothing works now. Any suggestions? Seems like there is a timer or something and when I did have picture the last time, it was great. I tried all the settings and couldn't fine a timer setting.
