Nathan :

Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.

Sorry to hear you’re having trouble.

Nathan :

What type of speaker/sound system are you using?

Nathan :

When you say it happens mostly on films, do you mean things you've recorded OTA, or bluray discs?

Hi Nathan

JACUSTOMER-qkiukt9w- :

I have connected two entirely different video monitor/sound systems via HDMI lead with the same effect.

Nathan :

What specific things does this happen with?
What sound systems are you using? Tv speakers or a surround system?

JACUSTOMER-qkiukt9w- :

This effect occurs on broadcast transmissions and is present on recordings I make on the set top box

Nathan :

Can you go into the setup menu on the box and set the output format to pcm/stereo, rather than dolby/digital, and see if that helps?

JACUSTOMER-qkiukt9w- :

I have connected an LG monitor with internal speakers and also a

Nathan :

If that setting doesn't help, you can try a quick reboot by unplugging power at the mains for 60+ seconds as well

and if still no change then attempting to update the firmware on the panasonic would be the next step

JACUSTOMER-qkiukt9w- :

Samsung monitor with external speakers.

JACUSTOMER-qkiukt9w- :

I have rebooted and have the latest firmware installed.

Nathan :

Try the analog outputs (red/white) and see if sound is any better that way. If it is, it indicates a hdmi issue with the box.

JACUSTOMER-qkiukt9w- :

I have not tried that. I will try it and get back to you. Thanks Rick

JACUSTOMER-qkiukt9w- :

Hi I'm back. There is no analogue output on this box only HDMI and optical.

JACUSTOMER-qkiukt9w- :

I should say that the majority of the time the sound is perfect.

Nathan :

Do you have anything you can test the other (optical) output with, such as a soundbar or theatre system?

Nathan :

It's hard to say also with only broadcast content if it is an issue with the channel/broadcast show, or if it is the panasonic. Do you have any issues with dvd playback?
If you check those same shows using the tuner built into the tv instead of the panasonic, how do those sound?
