Hello,
i am new to Philips TVs and own this one since Saturday.

Unfortunately i experience problems since then.
TV is on Internet over LAN Cable and Firmware is up-to-date.

Watching TV on cable analog or digital is ok.

Connected are
Denon 1911, PS3, Sony BDP-S350 and XboX 360.

Video is always OK, connected directly on the TV or with Passthrough via the Denon.

But sometimes (about30-40% of tries) there is a serious sound issue when switching between the input devices or between internal or external sound.
It does not matter if the devices are connected through the Denon or directly on HDMi1,2 or 3.
The issue is that the internal speaker does no sound at all, or
the internal speaker is totally blurred (like scratching on a white board).

This failure even persists after switching from the input with the failure to other input devices OR the internal TV cable receiver.

The failure is gone after turning the the TV off-on.

All devices were working on a Sony 40" LCD display and all cables were changed.

I think this is software problem, please help.

Thank you,
Robert

This does not help.
The failure is not constant. It just comes sometimes when switivhing between Input channels.
One Moment there is sound on internal speakers while watching BD (directly connected), then i switch to another HDMi input and back, voila, sound is gone (50/50 chance)

Hi,

does this happen if you disable EasyLink?

Yes, disabling Easy Link does not help.
However i have the feeling that i happens not so much with it disabled.

Hi,

Is there a firmware update coming ?
T-Series already had one ...

Thx,

I have had this effect on my 42PFL7606K02 about 2 or 3 times, too.

Same issue on my TV. In my setup I have disabled the audio throughput on my Mediaplayer, so when watching a movie the TV remains silent.
Almost 80% chance that when I switch back to another input device afterwards, the audio is broken on the TV.

This failure still exists after update to newest firmware from October (14.76.)
