Mono/stereo flashes in upper left tv

This is the third tv this has happened on, all different brands. In the upper left corner the words mono and stereo sometimes alternate sometimes together with a /. I have a seperate sound system hooked up and sometimes when both words are on, I get a loud crackling sound. Usually it stops when the words go away,but once I had to turn off the sound system. Anyone know how to get rid of this? Thank you. I saw something similar on this website, but the only answer post was someone whose "solution" was to take it back to WalMart. airmac19

The mono/stereo is an indicator of the audio signal that the TV is outputing. Like most car radios, they have an indicator that tells you when a station in coming in clear, which may be just an LED or a light. When the signal is weak or when your on a non-stereo station the indicator will not be on. What signal are you providing to the TV? Cable, OTA, STB output??? low RF signal level could be the cause for this.

My philips tv stays on mono, no sound when i connected to auto or the antenna model no 27ps55s121

You might have to enter its service mode option to make it stereo. Visit the site named 'Electro-help' for more details. Click this link. View it in 'Flip card' option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy. Some times, the ads attached with each posts, both at the right and bottom, might help you to find the availability of spare parts. There are more than 850 posts to different brand TVs now.

How do you stop the word "stereo" from flashing in

You have either a bad cable or weak signal causing the stereo to go in and out. either try a new cable from the outlet (if you have a splitter, disconnect all but the tv and try it). or switch to MONO in the config setup.

Mono to stereo

You can't convert mono to stereo since the TV only has a single input, and not the separate right and left channel circuits needed for stereo. If you are connecting a stereo source like a DVD player, what you can do is combine the right and left channels into one and connect that to the mono input. You need an audio Y-adapter with two RCA jacks going into a single RCA plug. These are available from Radio Shack. If you are outside the US, there should be local sources such as a stereo shop where you can find the adapter. This won't give you stereo, obviously, but you will have all the sound.

QUESTION!!!

It may be a setting on the TV some stations only broadcast in Mono. But most likely check your tv settings and make sure it is in stereo mode.

I just bought a Sharp Aquos LC-32D64U and a Box in the upper right hand corner keeps popping up "Air Analog Ch. 3 Audio Mono/Stereo." The audio keeps flashes either mono or stereo and it does...

The following pretains to most TV models:

Check to see if there is a key on the remote that is called "Display". This is normaly used to display the TV's operation status. Press it and see if you can work your way through different modes of the display content for the screen.

If you cannot make the statis dissapear, it is possible that there is a fault in the incoming signal and the TV is indicating this error, or it is possible that there is an actual defect in the set. At this point, I would contact the dealer. If you don't get a satisfactory answer, then you should contact Sharp service directly.

With retail dealers in many states and countries if you are dissatisfied with the set, you should be able to exchange the TV set in a specific period of time depending on the local laws that deal with consumer sales.

Volumne on Akai LCT3285TA

Often a signal might experience a super-quick "drop" in signal strength, and the display is automatically adjusting the now weaker audio signal to "mono" (temporary, as for best quality). But the dropout is usually so brief you will then see the "stronger" signal restored [full strength], and now the audio is "stereo".

It's like a "bump" or "disturbance" that occasionally affects the cable/satellite/OTA (antennae) signal being fed into the TV, and your display's attempts to compensate for the weaker signal [going to mono, then back to stereo once back to full strength].
Connecting it to your cable directly (bypassing the box) or an antenna would give you a true over-the-air signal, which would be proper MTS and would not give you any more pop ups.

Stereo/mono on iLo 42 screen tv

I have encountered the same problem. I have looked through the menu at least a hundred times to find an answer, but the only thing that I have been able to come up with is to push the MTS button on the remote.
