TV purchased from Wal-mart about 3 years ago. About a month ago, trying to turn the tv on required that we press the ON button and hold it for almost 2 minutes. Now when the green on light finally came on, NO PICTURE. It would indicate on the screen "no signal". If you try to turn it off, it wouldn't turn off. Had to unplug the TV from the wall. Paid about $800.oo for this piece of crap. I have a Motorola TV from 1985 that works so much better than this!!! read full review »
