I have the same tv same problem. This is what I did . I removed the main board. Preheat your oven to 385. Place the main board on top of a piece of cardboard. Then on top of a baking sheet. Bake it for 10 mins. Open the oven and let it cool for 20 mins. Re install. This worked for me. Tv turned on and works. The problem seems to be the solder under the processor chip overheats and cracks overtime. When you bake it, it re solders the chip and makes connection. Hope it helps you. Btw. I had to bake mine twice, the second time I turned the oven up to 400. Temps differ from every oven.
Smart tv's have their own built in computer and as with any computer they can get confused and don't know what to do.a simple thing to try is unplug your tv completely from power source including a power strip. hold the power button down for at least 60 seconds plug it back in see what happens. don't cost anything to try this.
SOURCE: red blinking light three times pause then three
Make sure that lamp door is fixed securely and pressing lamp door switch as 3 times blinks shows lamp door switch is not On.
SOURCE: red light blinking 7 times on Sony Triniton Wega TV
This means one of three things, either the lamp is bad on your tv, the ballast that powers the lamp is bad or the safety switch for the lamp door is not depressed or it has come un-plugged. It could also mean the power supply or fuse on the power board is blown. I am assuming this is a DLP tv, and if so, it is fairly easy to fix it or find parts for it online. If you are slightly mechanically inclined, want to save money and dont mind paying attention to detail then you can fix it yourself. If you need help dont hesitate to ask.
