The TV is a year and a half old and suddenly has no sound. Picture is find but zero audio. We can get closed captions to show up, and that's it. Any ideas of how to reset to default settings or if it's a mechanical failure?

From your description of the problem it sounds like you may have the "closed caption" turned on in text mode.
Look on your remote control for a button labeled CC or CAPTION and press it repeatedly until it says OFF.
Otherwise you may find it in your tv`s menu under "closed caption" .
You just need to turn it off.
Sound/volume problems seem to plague this model TV. Check the electrolytic capacitors in the audio amplifier section - if the tops are puffed up, they're blown, and that's why you have no audio. FIX; replace blown caps WORKAROUND: turn on closed captioning, or turn up audio on a nearby functioning TV tuned to the same channel. CAUTION: turn the sound down below 60 - these audio circuits have a reputation for intermittently coming back to life.
Display distortion can be caused by close proximity of other electronic devices which interfere with broadcast signals. Try moving other electronics farther away. More details and tips can be found in the owner's manual.
Thanks for using FixYa. Due
to two things that will cause the No Signal message to come up are – no data
available for closed captioning and a weak signal input. Your TV is in the
Closed Captioning Mode. To turn off simply bring up the on screen menu and
scroll down to the part that says closed captioning and turn this function off!
With the closed captioning block displayed and the program being viewed is not
sending out closed captioning signals the TV will display, No Signal!
If this doesn’t resolve your
issue then the problem may be with the processor failing and it is causing a
random read of the EPROM to display the No Signal message.
I’ll suggest you to run the HDMI
from the PVR (personal video recorder) directly to the TV (mute the TV), and
then run the optical audio from the PVR directly into the receiver's optical
in. The closed captioning is something that is addressed in analog broadcasts,
but not necessarily digital broadcasts.
Try using Component cables if
this doesn’t make a difference. After using components cables your issue will
Please do accept the solution if
the issue is resolved or else revert for further assistance.
This is a problem with closed-captioning. What you are seeing is a closed captioning box with no captioning in it. Usually this is being accidentally transmitted by the cable company "head end". Just make sure your closed captioning function is completely turned off. if you are seeing it randomly, it may well be coming from your cable company. Is it just on certain channels?
The closed captioning has to be sent in another language, and your set will follow it. Call the TV station to find out where they are getting the captioning from, or maybe they can get you directly in touch with the captioning people.
The closed captioning is sent as one of the many information packets during the vertical blanking interval. In the NTSC system, it is sent on line 21 in both the even and odd fields. There are usualy 2 closed captioning selections for text. These are the CC1 and CC2. They are decoded according to their address code.
