I have a 7 year old WS 65819 which was running perfectly now suddenly the TV won't power on, the green light will blink when I plug the TV in. Then when I power on, the green light will come and then after 40-50 seconds it will power off. But if I unplug the TV for around an hour and then plug the tv back in and then power on, the tv will come on where I can see the picture for 40-50 seconds and then it will power off by itself.
Any help on this would be really appreciated. I think the fuse should be OK as I checked them and since the picture comes on sometimes.
