Hiya fellow PK950 owners! Anyone of you who tried the "pot tuning" tweaks talked about recently in the PZ950 thread?

If you have, please share your experience in the new thread devoted to this: http://www.avsforum.com/avs-vb/showthread.php?t=1372479

Unfortunately, with LG often it happens, it's good to check their panels. On my PV350 already have 6 "problematic" pixels. Fortunately not see them during normal viewing of 1.8 meters. Maybe as it will end with a warranty, I will give it to the service panel may exchange or give newer model ^^.

I don't think stuck pixels are limited to LG panels.

I'm not too concerned since it is not visible during normal viewing.

Hi, I have a Harmony xxx and was wondering if there is no way at all to enable direct input for my LG 50PK950 tv?

Just to be clear with direct input I mean being able to switch to HDMI2 with the touch of a (one) button.

I have a Harmony One and all of my inputs switch directly, both through my activities, and in Device mode, where each input is on a soft button.

Hello, I received my 60PK950 in February of 2011, so it's about 22 months old. I have absolutely LOVED this set until recently.

I've noticed a severe buzz that started about a month ago. Didn't think much of it at first as it went away, but the buzz has been happening more frequently and it has stayed buzzing for a longer time.

I know buzzing is inherent to the plasma technology. I actually returned a Samsung plasma because of it and got the LG instead.

I'm looking for insight into the issue and how to fix it. Any help is appreciated. Thanks! -Gordon.

I also have occasional buzzing. Especially at cold starts, but sometimes even then when it is already warmed up and the picture has lots of whites in it, which often happens for me as I'm using my desktop PC with it. If both conditions exist, the displayed taskbar might flicker as well.

I'm not sure if there is a solution to it. Let me know if you find out anything that could help, but my assumption is that more energy the TV needs, the greater the chance that it would start the buzz. rolleyes.gif

Try to change the settings of brightness/contrast/temperature/etc just to see if it is the case.

Hey everyone. I have tried to google for this, but I cannot find a clear answer.

I have a LG 60PK950 and am wondering if the HDMI > TV > Optical Out pass through is just 2 channel audio or does it pass through 5.1 audio?

I don't have a home theater for it. Currently just use the tv speakers. I want to buy a Samsung HW-E450 sound bar (only one optical in) for it and am wondering if the optical out will just spit out 2 channel audio only, as my bro's old DLP only spits out only 2 channel audio on its optical out from a source that is plugged into the TV from HDMI.

I mainly watch my HD cable box and apple TV on this tv. these two are plugged in via HDMI to the tv.

Any help would be great.

Thanks.

All my HDMI inputs suddenly not working. It says no signals but components inputs are working. Any idea what went wrong and what can I replace to get it work again?

I just came here to post the exact same issue. I originally thought it was the output on my receiver that was fried, but then plugged both my Wii U and my HTPC directly into the TV (in different ports), and none of them are working -- I just get the spinning cube w/ the "No Signal". Awesome.

I'm hoping, tingshen, you found an easy, inexpensive solution. Really don't want to pay hundreds of dollars to fix something that may just break again, nor am I ready to buy a new TV.

Hello - My 60PK950 is having the same problem - none of the HDMI ports will connect anymore. It just displays "no signal." The HDMI ports are sensing the devices connected. They will grey out when the cable is disconnected. Did any of you find a solution for this? Thanks for your help.

Unfortunately, it required replacing the TV's main board. The good news is it was a quick fix -- the technician was in and out of the house in under an hour.

The bad news is that it set me back a little over $300.

Thanks for the reply. Was it the board that contains the HDMI ports? I think I could do it myself if I can find the part.

Yeah, you probably could do it yourself (I would have, had I know how easy it was). But it's the main board that pretty much has all connections coming into it. I think that piece alone is $150-$200.

Same problem here. I bypassed the issue by running video in via RGB. Picture looks every bit as good, so I'll leave it as is.

Hi everyone,

I have had my 60PK950 since they released and it's now that suddenly I get a loud unnormal buzzing from the set, mostly from the left upper back when facing the set from the front. I noticed that sometimes now it gets louder when a screen is bright or is majority white, but it chills when it's dark or mostly black. Sometimes I hear nothing unless I go behind it and focus on it, which is normal from my experience. When I put my hand over the left back or turn the tv slightly left and right and back to center the loud buzzing seems to go to normal.

Anyhow, does anyone have an idea what is actually going on or how I can address it? I find this odd and I fear that my tv might be close to suddenly becoming a loud buzzing annoyance or crap out on me. Normally I wouldn't be so bothered because it would just mean upgrade time, but money isn't falling off trees of late.

Thank you in advance to any and all who chime in.

May be the power supply or one of the panel drive boards- best thing to do is pop off the back and try to see if you can isolate the sound to a particular board and if so, replace that board.
