This monitor has stopped turning on after being turned off for a day. The speakers just start clicking and don't stop for about 6-8 seconds after you turn it off and the light flashes green. If you turn it back on within a second or two of the light going off it turns green, flashes a "No Input Signal" screen, goes black, and starts clicking again. After doing this about 30 times it will turn on completely and stay on. Does anyone know what the problem is?
