Any TV repair guys here???
We have a Panasonic Viera TV.
Got it in 2010.
Problem is every once in a while, the voice is garbled.
It sounds muffled, with an echo.
Last around 10 to 15 minutes, and will go back to normal.
If we turn off the TV, and turn it back on again, it will go back to normal.
This is and older model, so no self diagnostic feature.
We just had to change to digital with Rectum cable.
Was fine before.
We had the cable guy come and check it.
He repaired a cable, but said it's probably the TV, because it only happens to one of the TV's we have.
Other than that, it works fine.
I would think a TV would last longer than 8 years.
One we had before it lasted over 15 years.
