The problem I am having is when commercials come on or the camera switches, etc, the audio cut sout for 5-10 seconds. it's almost like sit's having to handshake again with the TV (even though it's optical, so there is no handshake like with HDMI). Any settings I can change?
Thanks

Receivers typically have some sort of lag when they switch modes.. ie 2.0 to 5.1 and I would imagine that a sound bar would experience the same issue. This would only happen when you change channels or a TV program goes to commercial. This shouldn't happen when they switch camera angles.

On your setup.. I don't understand.. do you have the devices connected to the TV via HDMI and then you are passing the sound thorugh the TV's optical? Usually the TV would only output 2.0 PCM sound anyway, not DD 5.1, which I believe is restricted in the HDMI spec. The only other thing I can think of is the handshake is happening between the TV and the source device and that handshake delay would also "mute" your soundbar until the TV handshake is complete.

Another problem with my PK550 - I have green "noise" on the screen - Any way to fix?

All PK550's having dancing green pixels due to the dithering algorithm the TV uses.. It was designed this way. You shouldn't be seeing the pixels from a normal seating distance though. Move back if they bother you.

Thanks! I really appreciate the help. The sound bar issue is a problem with... the sound bar! cool.gif Some googling determined an issue with the PCM handshake on input 1. Changing to input 2 has solved the issue. I will have LG replace the sound bar, as they are replacing it due to the issue for users I have read about on other forums.

Thanks for the info on the dancing pixels! I wish I had asked earlier, I have replaced the HDMI several times to no avail, and was beginning to think the TV was at fault. "Glad" to hear it's a normal issue.

Thanks again.

Hey guys!

I had a question pertaining to the blue plastic trim on the bottom of the LG PK540 I own. After moving it several times it has come loose. There seems to be a screw in the middle that releases the middle section of this frame, but has anyone successfully taken this little piece of trim that runs along the bottom off? It's a real hand cutter when wall mounting it or moving the TV. Stupid decision on LG's part IMO.

Nobody responded to my initial post so I will try again cool.gif

Does anybody know of a way to do a Master/Hard Reset on this TV? confused.gif

Thank You

I've had my 50PK550 since November 2010 and it's been a good TV until yesterday when it developed a thin horizontal black line.

It doesn't even need an input for it to show -- it's clearly visible when there's no signal, when it's connecting, etc.

I guess it's time to find my "proof of purchase" and give LG a call. This should not have happened after only 21 months or so of ownership. My 2007 Panasonic plasma doesn't have any issues.

^ Unfortunately I'm experiencing a similar issue on 50PK550, it's got a thin green vertical line going down it. Very disappointed that this soon I'm having issues with what's otherwise been a great TV.

rant on/

I have a green vertical line 2 pixels wide direct center on the screen. Thanks for the 2 years and 6 months LG. Will cost as much as a new TV to fix. Going back to Panasonic. Should have known better than to buy a cheap ( $1700 ) TV. Never again LG.

Buyer Beware!mad.gif

Happy Thanksgiving!smile.gif

Yep, panel is covered but not labor which could be $$$$ and you only get a 90-day warranty. Back to Panasonic for me too. My 50" 720p Panasonic from 2007 is still going strong. Panasonic 55ST50 is looking good...

This set has turned out to be a huge disappointment for me as well. I have 4:3 burn in now, with brightness being always set down and the limited content we actually watch in 4:3 I can't believe it actually happened. The video tearing issue that's been reported a few times for me is still happening regardless of how many parts the techs that came out replaced. I really received a lemon of a TV, but hey..there's always taxmas. This time I"ll be going with a Panasonic or possibly trying my luck with an LED LCD. This one will probably be retired as a second TV or I could sell it cheap to someone who doesn't mine a little burn in, lol.

Sorry about our luck you guys!

Hey, I had a line just like that (but vertical) show up after 1 year from the date of purchase. I complained to LG a lot and they ended up sending a guy to my place with a brand new panel, he opened up the TV and switched the Panel. I got a brand new panel but I have a feeling it will happen again at some point :/

Apparently the the Panel has longer warranty (2 years?) than the rest of the TV.
