Hello, so the sound on my Panasonic Vista Tv becomes distorted after about an hour or so of watching it. Ive tried hooking it up to a Soundbar, but that also becomes distorted after an hour or so of watching it.
Is this a good question?

Hi @odinist,
Just a follow up thought, I was looking to see if there was a firmware update for your model, just in case it was a known issue and came across this (scroll down a bit and click on the support link to the right of specifications)
Check what the software version is in your TV. Go to Menu > Setup > about (I think)
If you have an earlier version firmware installed and you go to update the firmware from this link, verify that it is your exact model TV that I have linked, as installing the wrong firmware can brick the TV.

@odinist since the sound distorts on the sound bar as well my prime suspect is a failed/failing amplifier IC It is on your main board so see if you can identify it’s location etc. If you do not have the tools to replace an IC consider replacing the board. Since we do not know the exact model of your TV we can be of no assistance with that.

Hi @odinist ,
Can you try connecting another signal source to the TV e.g. dvd player and check if the audio also becomes distorted or not?
Just trying to conclusively prove whether it is the TV or not.

I've tried everything. The only time it does not become distorted is when I have a gaming console plugged into the audio and video area. The yellow/red/White. And ive tried 3 different HDMI cords. A soundbar with the optical audio cord and it becomes distorted. It does it after about an hour or so. I usually have to turn my TV off and back on and it fixes it for awhile.
