Vizio or Visio television are substandard sets. I'm sorry to hear that you pruchased from Wal-mart or Target.

You might as well chauk this up to learning experience and get yourself a real set from a real dealer.

No repairs are possible within an economical prince range with your unit.

Sorry to break the bad news.

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

that can be caused by either the IR sensor board or the main board. The IR sensor board would be suspected first. You can get the IR board or the main board from www.tvrepairworld.com

My tv [vizio vf550m] won't respond to a remote.


Vizio is famous for having main board issues. If you have replaced the IR board the only two other items it could be is a broken wire from the IR to main or the main board has an issue. Nothing else can stop the remote from working provided the remote is working properly.

Vizio m470sv remote stopped working, bought a vizio replacement remote...still no good????


What you are dealing with is not a bad remote controller, the problem is from your IR Sensor. You will need to replace this IR Sensor. You Vizio TV has a common defect with the IR Sensor. Make sure you order the revised version so you don't encounter this problem again. You can find the IR Sensor here: 3637 0022 0189 0171 1671 0892 Vizio IR Sensor

How to replace olevia lt37hvs ir receiver replacement


You may find this is impossible to do---the receiver if the set has buttons on front will be located there--if on same tiny circuit board as buttons you will have to TRY to find a replacement board--Good luck as this brand often NO parts are available.

While all IR receivers are similar they have different values and mountings.

I will presume you had the remote itself TESTED which will rule it in or out.

Ir receivers sometimes show no function unless remote is right up very close are bad---they also of course can fail where there is not any responses shown.

Flat Screen 42 inch Vizio does not respond to the remote, called Vizio tech told me to take out batteries and push every button, replace batteries and try. Worked for 3 minutes then stopped again,Replaced...


You can use your phone camera to test the remote. Place the remote to the camera and push to see the IR on the camera. If this works for more than 3 minutes then the IR detector or the processor circuit in the main board is faulty.
This means you need to remove the main panel and use a multimeter to test when the remote is used, trace and see if the fault leads further to the processor.

Vizio 37" no longer turn on


It depnds, if the board is labled with voltages at the DC output connectors or not, if not, you will have to trace out the connection to find out which one is 5vdc standby, switched 5vdc, 12vdc, and 24vdc (I have to do that all the time when I work on circuits without diagram).
