we had a similar issue, the tv would come on then shut off and we had a red blinking light. we purchased our tv from costco a year and half ago and thought there was nothing they could do for us, but i called them anyway and they fixed the problem over the phone. what you need to do is if you have hd tv and are using a receiver unplug the hdmi cable from the back of your tv. then you need to unplug the tv only. hold down the power button on the side of your tv for one minute. now you want to take the batteries out of the remotes that control the tv. i had to take them out of both the phillips remote and the reciever remote. do one at a time. you need to hold power button on the receiver remote for at least 30 seconds(i have 2 power buttons on my receiver remote, one for the tv and one for the satellite, do both but not at the same time) then you need to do the phillips remote as well. this fixed my problem, i hope it will for you as well. apparently the tv needs the static removed and this is what will do that. good luck
