I have a Sylvania Plasma TV it is 11 years old. Out of nowhere, went to turn tv on and it flashed from green to red. Sometimes if you keep pushing on it will come on. Other times you can keep trying to turn it on it will stay on red. Then we unplug the tv for about 10/15 minutes then plug it back up and try again. You can hear a clicking sound like it is trying to cut on but it doesn't. TV has an awesome picture never by problem until this. Also, we have always used remote control to turn it off and on. Any info at all on what I might could do to save the tv or is it useless. Thank you, Marilyn
