My Vizio 47inch TV made a loud pop and shut off. Pulled back off and inspected for anything bad. Located a tiny resistor looked like it was burnt or something can it be fixed?


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; [Exclude the model number], in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

My vizio tv will not turn on


I have repaired many of these over the years. Vizio s have regulators on the main board that have been failing causing this problem. You can verify that the power supply is working by the Vizio em-bloom lighting up on the front of the set. Hope this helps. :)

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
