Is the sound coming back when you switch off/on your Philips TV?

Well, I honestly can't tell, cause I have always assumed the problem is the DM800se itself.
So I've actually never switched only the TV on/off (as I can remember...). But surely that would be a good idea to start eliminating the source of the problem...

Today the sound suddenly disappeared while watching (Not from standby).
I turned the TV off and on again and the sound was back.
I have yeat not changed the HDMI cable, but will continue using the old one while investigating further...
So atm. I can't tell if it's the DM800se the TV or the HDMI cable causing this...

Yes, the box is an original DM800se.
As to the sound disappearing while switching channels or satellites, I don't mean the sound disappearing in the exact moment i switch.
But more like some time after (5-20 min.) I can't tell for sure if it happens more frequently then (maybe it just seems like it..),
but at least it can happen at any time while the box is in use. And also as you describe when switching on from standy.

Haven't really thought about changing the HDMI cable ,
but I will definitively give it a try and see if that resolves the problem.

This seems to be the exact same problem as I'm having with my DM800se.

Suddenly the sound simply disappears... In my case the sound also starts cracking up sometimes before it goes away.
Sometimes all it takes is a restart to get the sound back, but sometimes the problem still persists.
And as you you describe, disconnecting and reconnecting the HDMI cable resolves the issue.

I can't either seem to figure out what's causing this,
but it seems to happen more often when switching beteen different satellites, possibly also HD channels, but there's no clear pattern.
I actually have thought it to be a problem with my LCD-TV (Philips), but after reading your post, I'm starting to think this might be related to the DM800se.
I have had this problem using the image from LT-team, but the problem also happened after i newly switched to latest PLI-image.
So it seems to not be related to this specific image. Maybe it's a hardware issue or some common driver(s) causing this...
I really don't know...

But at least after reading your post I think I'm not the only one having this problem.
