Hi. Is there any hope of finding a chart/list of the remote codes emitted in infrared that control a TV ?
I can read the emission codes from the remote with an oscilloscope, but how to find out if they are correct for the TV to respond properly ?
How rare would it be for the codes to corrupt/alter ?
TV is a Vizio M470SV not responding to its confirmed emitting remote.

 

Was the remote supplied with that TV?
There is a lot of information on the web about remote controller codes.

Have you tried replacing the battery in the remote controller?

There are, but you need to find them and for your model, e.g., http://www.remotecentral.com/cgi-bin/forums/viewpost.cgi?925066

There are also know problems/solutions with Visio IR receivers, e.g., https://www.shopjimmy.com/vizio-3632-0172-0189-ir-sensor.htm https://www.youtube.com/watch?v=orIrNKzryDo

I would suggest another step first. Read your remote code with an Arduino and an IR receiver and see if it is clean. You can even clean up the received signal and rebroadcast it to test the Visio, e.g.,

There is lots of info and code out there on this subject., e.g., https://github.com/z3t0/Arduino-IRremote

 

Thanks.
Yes, original remote, confirmed it is emitting IR as seen with a camera.
Any site suggestion to find what is its corresponding power on/off code ?

Not beyond the ones I posted, you will have to search. But, there are many common codes...don't expect all unique codes for each model - many Vizio will be the same across a number of models.

I know those seem pretty basic, but they are worth the few seconds it takes. Also, I would hold hte remote right up to the sensor.
