Having problems with your Samsung SyncMaster 940MG 19" LCD Monitor ?

TV switches on, then instantly switches off.

\015 When the remote is pressed, the TV switches on (Green LED) and then instantly off without even a chance for the display to come up. There is a slight colour change in the screen when it switches. \015\012If I keep switching it on for perhaps 20 times, it then switches on with the green LED saying on, then two initial very loud audible cracks are heard through the speakers finally followed by the correct image display. I hope someone can help.\015\012\015\012Kindest Regards\015

I would take the batteries out of the remote and try turning the monitor on manually. Sometimes when the batteries get old it will do what you are describing.
