Sound stopped working on my vizio M42osv will not work with head phone jack sound bar , optical or hdmi
You have to check the audio settings of your tv. There would be n option which allow you to choose the option between internal speakers or external speaker. You have to choose it as external speakers of amplifier.

My 37" vizio I bought in Dec 2007 did this (green screen at start-up on all inputs). At first it went away by itself after you left the unit on for 15 minutes, but then 2 days later the whole thing DIED. Luckily Costco has a 90 day return policy on TVs.
Vizio tech support suggested this (before it died that is):
Please
try to reset
all setting
and then to see if the problem is solved.
1.
Press the Menu on your Remote Control;
2.
choose Set up on the OSD;
3.
then choose Reset All settings;
4.
Press the Exit on your Remote Control to remove the OSD.

I had the same problem. I could get an analog audio signal but no digitial signal. My problem was with the cable box setting. I have Cox Cable. With the Cable remote I went to settings/settings/Audio out and selected HDMI. Worked like a charm

You should verify if the remote has failed. Contact the support for Vizio, or ask your dealer where you can buy original replacement accessories.

Most of the time, we've seen the remote fail. Sometimes we are able to service the remote. Sometimes, the IR LED and or the crystal fails in the remotes. If it is more than this, it is impossible to have internal service parts for most remotes. It takes service experience to be able to change these parts.
On rare occasions the IR remote sensor and remote processor area in the set can have a failure. It is best to try another remote to verify this before sending the set for service.
The most common causes of failure of a remote controller is dropping, rough handling, getting food and drink inside, or putting the batteries in backwards.

If the TV goes in standby, then it is in protection mode.
Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.
1The
internal circuits are jammed because of electrostatic
charges accumulating on capacitors, or because of a wrong voltage read
by the main chip on your monitor controller board. this started the
protection circuit.
2 The protection circuit detected a wrong
voltage or abroken contact, identified an internal fault and kicked in
, starting the flashing light.
If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay
particular attention at inverter and power board, power board can be
inspected looking for bulged or leaking capacitors, then tested with a
multimeter. The inverter is more difficult to test , there is need to
read voltages, should be done by a tech. Also the LCD controller board can cause same problem

Hi, I had the same problem. My vizio remote for my 42 inch 2 month old vizio also seemed to stop working. Here's what I did: My vizio remote (like most remote's nowadays) was designed for multiple components (tv, dvd, vcr, etc). All you need to do to make the remote work again is set it back to tv. Now, the confusing thing about vizio remotes is that they actually have TWO places where you can switch the remote to the appliance you want to control. One is on top of the remote, the other is on the BOTTOM. Switch it back to TV using the BOTTOM. My remote had stopped working because I had inadvently switched it to another component on the BOTTOM component switch.
