The last 2 days have been technically a fantastic year. It started with 2 Harris Butt Sets and ended with a fixed Vizio 47" TV. I had recently failed a cap replacement on an Insteon device, so my electronics repair road was on a bad path. It felt good to relive my roots.
The TV a Vizio SV470XVT1A was an interesting one, it intermittently displayed video, the back lights always worked. Lots of documented voltages finally lead to a voltage regulator U10 on the daughter board, 0101-4072-0044 which showed a pin hanging at .4 mv when the set failed, and came up to 1.1 mv when it worked. What a deal, the daughter board is near the cheapest one in the unit. Amazon had a seller with a used one for $8.
