Question about Televison & Video
3 blinks indicate that the power source is in protected mode because one of the components of the tv has failed and now acts as a short. The only way to know for sure which is the failed part is to open the tv and measure the voltages on the output lines from the power source - the one that is going to be close to 0 will point to the failed board.
Most likely it's the power board itself - one (or more) filtering capacitor has failed, a common problem in tv's of that age. But it might also be the Y-sus board - Emerson uses old Sony parts and they were notorious in that regard.
