This is likely due to heat expansion (turned on) and contraction (turned off).

SOURCE: my vizio vx32l will not turn on. vizio logo will

The main board has failed. Replace the main board will fix the problem.

By the way, where did you buy the TV? If you have bought it from Costco then try to give them a call to see if it still under warranty.

Hope this will help.

SOURCE: Power is there, but TV won't turn on

stored voltages are high no touching these circuts becuase they hold charges and alot of screws.
fualty capacitors you say after a while it stays on theres a full charge in the unit theres some type of discharging effect on the set after its off for a while. voltage goes to low or unstable after it is off for a while. your better off getting the service docs for this set if you want to diy..other wise get a tv tech to check it for you. hope this helps

G'Day!

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.


I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.

SOURCE: loud buzzing noise on vizio tv

It sound like you may have sound processor problem which is part of the main board, I would also look at the 12vdc from power supply to make sure it is clean DC.
