So my neighbor comes to me toting this massive 48" TV. I help him into the house and we set the behemoth on the floor.
He proceeds to tell me it wont turn on and that his son who "works on computers" looked at it and couldnt find the problem.
Being someone who works on computers professionally, model railroads in O scale, and does electronics work for fun, I dig into the tv.
First things checked was the cord, the wires going to the power board and then the fuses. The primary line fuse (8A) was solid, while the 5A going to the inversion circuit was reading open. Replaced the 5A fuse with a slow-blow glass so that I could witness the carnage. I put on my safety glasses and energize the circuitry.
For about a second, I hear the brief hum of a transformer and then its quiet. I look at the secondary fuse and it had warped from blowing.
The board is: EAY36781301
The caps on this board look quite stellar, but the heat shield has discolored dramatically.
