My vizio m421nv TV has no sound when I turn it on. Have to turn it on and off a few times before it has sound.


Fault with the main power supply regulator 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. Surf the site with patience. 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.

Video board failure vizio M470NV


Vizio M470NV is an economy class LED TV made by Sharp for Vizio.

The main board in it suffers from a few problems that are actually common for the Vizio LED TVs made by Sharp and based on the same design and built with the same pool of components.

It took time to TV repair shops, but now repair services and possibly even exchange boards are starting to become available.

See here for more details:
