I'm having this weird problem which I hope isn't too serious. I've got a PS3 and WD HD Media Player where both are connected to my Philips 42" PFL5403 thrugh HDMI. It's been working fine but recently I've found that I'm getting mono sound in my TV. This I wouldn't have bothered unless I was using my TV sound out to source my AVR, which doesn't support HDMI sound.

Now my question is what am I doing wrong to get mono sound? Isn't HDMI by default carry stereo sound, providing that the source is stereo. I've checked the sources, which are PS3 games and DVD movies, which I know for a fact have at least stereo sound.

I really need someone to shed some light in this issue.

Thanks everyone.

Did you check the TV settings?
Could be accidentally turn the TV sound setting to mono?
