I have a Samsung 40inch 750 series, ive never had problems with this TV before... out of nowhere i went to turn it on today and it doesnt work.. the tv keeps turning on and off on and off when its plugged in.. i have to unplug it to stop it from turning on and off... it just shows a blank screen for about 1min then turns back off then on again on its own... does anybody know how to fix this or has ever heard something like this before??? please help
