I just bought a magnavox 37" at wqal mart for a very cheap $ 598, because it was the display model. The picture is very fine, the only problem is that it takes 3 or 4 times of me pressing the on button before it decides to turn on. At first the green light just blinks and then it turns off so I try it until it works. This does not happen when the tv is already on and I turn it off and on, it only happens when the tv is off for a long time. What can I do about this problem and is there a cheap way to fix it? Any advise would help.
