Since there is no red light, did you check that power outlet and did you try another power cord as well as try to turn it on with the buttons on the TV?
Can someone help me answer this? My Samsung TV is just a little over 2 over yrs old and it just stopped working and does not turn on and even the the red light does not come on on the TV. Called Samsung and waiting for their service repair person to call me back as I do not have extended warranty. Did anyone have the same issue? Or know how to help me resolve it myself? Please help.
