Audio is great and under control for the most part however in the past several weeks it will either go to Max volume & then shut offr or more
commonly the volume will fall rapidly to zero. We can bring it back by tinkering with the MENUE Audio controls but we are never sure what will correct the problem. Some times shutting off and then restarting will fix it. Any suggestions how to fix?

There are to components to be suspected. Its speaker, and audio output IC. If speaker has any internal disconnection occurs, to its voice coil connection braid wire, the said fault can occur intermittently. If the audio output IC's contact between its heat sink has a screw loose, it will overheat after some time, and will shut down. It will work, after some time the set has been switched OFF. If there is any loose solder terminals to the audio output IC, this fault can occur. Just check these.
Press and hold the POWER button on the control panel for 10 seconds to perform System Reset. TheTv`s "Listen to:"setting may be set to SAP (analog program from the ANT input).Plug an unused video Plug into the INPUT3 Y/VIDEO jack to activate Auto Input Sensing and make the audio device selectable in the Activity menu;InputMode may be selecting unrecognized AV audio input ; Wrong NetCommand settings SEE OnLine Owners Guide
that hapened because your remonte contral has the + button pressed just release the volum + at your remonte and all will be ok
or try to hide your remonte control and get down sound from front panel of your tv
if you know anything about the tv, take off the back and remove the power supply board. Reflow or resolder the solder points, takes like 2 hours, but is well worth it as my tv works fine now. make sure to use rosin core solder and good luck
Good Day, corilyn;
Several things that you may try:
1. Unplug TV and Cable/Sat box for 3-4 minutes, plug all back in, that's resetting the devices.
2. Some boxes have volume controls, make sure 'box' volume are turned to max.
3. Go into TV's customer menu, go to audio section, make sure speakers are turned on/ set to internal speakers.
You have one of two possibilites going on here. Lets do the hard one first. (1) you may have a defective audio Amp IC. part # 264589 (2) The most popular cause of no audio on this unit is "the wife was cleaning the unit and hit the speaker int/ext switch on the back of the unit" This switch is a little hard to find. Its very close to the Video/Audio inputs. Its a sliding switch.
