In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

My tv won't turn on. it powers up then shuts off


Fault to the main power supply regulator section. 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. 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.

Why does my 32 in. Vizio make a loud noise and then turn off?


There is something shorting inside, possibly due to moisture collection. First, change input device to some other and see, if it works fine, the problem is with the input device. If you notice same problem, this may need attention by a qualified service technician.

Vizio makes loud static noise, picture goes fuzzy.


You should check your home wiring and grounding. Also be aware of anything that has recently been turned on when this happens. Anyone using a microvwave, cell phone, or other appliance that might be causing the interference.

Vizio TV issue


this is an indication that the power supply is working. The clicking noise shows that the power supply is booting up. If you still does not have power, it may be the main board that is not working.

Vizio Speaker Making a Buzzing Noise


My 32" vizio I bought a week ago does the same things.

Buy an external sound system for the tv. Turn the speakers off in the TV menu. Hook the sound system up to the out speaker hookups on the tv.

You will not only have better found, you will fix the speaker buzz problem.
