Official LG "XXLH90" 240hz LED Owners Forum [NO PRICE TALK] - Page 48

Forgive any error of protocol I may make here, I have just joined the group. I have been following it for a while.

I purchased two 47LH90s a little over 2 1/2 weeks ago. They both had AUG 09 manufacture dates.

1. They both show some audio lag using HDMI cables from DISH 612 DVRs. When I first called LG tech support about this they didn't know anything about "The Problem". I switched to Component cables and this has eliminated the problem.

I assume that LG has figured out how to update the firmware and that they will send out a tech to do this?


2. Regarding the picture settings. All the posts here for recommended Picture settings have the Black Level set to "Low". I have found that this "crushes" the black levels. If you have it on High then blacks become too gray unless you have the Gamma at Medium or High. I have been using the Brightness Level THX picture test on the Ice Age DVD to fiddle with the Standard (User) and Expert 1 mode settings (not the THX mode which is too dark). The "THX" letters disappear into the background with the Black Level set to "Low" unless you have the Gamma at "Medium" or "High".

Thank you

Rick

Gamma @ Medium & BL @ Low seems to be what is suggested. I just double checked the settings I posted a couple of pages back & notice I had Gamma @ Low, which was a mistake. I have adjusted my settings & put Gamma @ Medium..

Thanks for the feedback Rick & welcome to the club

I just got off the phone with LG customer service. I could barely understand the guy, which probably explained why I was on the phone with him so long. Anyway, I couldn't access my service menu either. I was able to access the firmware version though:

Bring up the menu using the remote, then highlight the "options" button (don't go into it), then type in 1111111 (seven ones). This will bring up a small window with the version number and update number, or at least it did on mine. 3.13.0-now I have to dig through here and find glangford's post with his updated firmware number.

EDIT: Crap! 3.13 is what glangford had his updated to & it fixed his issues. I have lip sync via the cable box HDMI and also via the component on my DVD. I rarely watch TV just using the TV's speakers, but I'd still like to know I have a 100% functioning display. Oh well, I still have a 3 week return window to think about it.

I still cannot get the THX letters in the THX test signals on the DVD to show up with the BL set to Low no matter what the Gamma is set to unless I totally whack the Brightness, Backlight, and Contrast settings. I am using a 7-year old Sony DVD player which is only 480p/480i and no HDMI out.

Rick

I just checked my firmware and it is 3.13 also. My two 47LH90s have AUG 09 manufacture dates.

Rick

I just checked my 1 week old 55LH90 (August 09 manufacturing date) and it has FW 3.13 along with the dreaded lip sync issues. The lip sync issues are not on all channels. TNT HD is bad where Showtime HD is perfect. I have Time Warner cable. Cable box is connected via HDMI to TV. I think this TV is going back.

Great find!

I guess mine shipped with 3.13 as well from Sept. 09. The thing about the lip sync for me is that it's not very perceptible - makes me think i might be nuts/paranoid, but i also think that the TruMotion 240 is kinda weird and will try the tv for a few days with it off.

Don't judge picture quality from these shots, naturally... also, forgive the dangling wires... I had to order some new cables long enough to fit in the wall as the 6's weren't gonna do it.

Thank you very much. This forum is great for researching problems. I also have the v3.13 firmware with a manufacturing date of Sept. 09. I guess this version helps non cable users....

I just found a outlet samsung LN55A950 (LED) on a sears close to home about the same price of the LG... this sammy can beat the LG performance overall???

Yes the Samsung is a better TV than the LG. Get a smuch information as you can on that 950 IE:

Has long it's been on the showroom floor
Is it a returned unit
If possible make them attach a BR Player & put a BD In see if you see anything weird

I noticed yesterday that I had lip sync issues on TNT HD. That is the only channel I've noticed it on since the update. TNT is known to have some problems in that area. Everything else is dead on. Watching baseball on TBS, the crack of the bat and the hit were in perfect timing. I've watched Numbers on TNT HD a couple of times and sometimes its right on, yesterday it was miserably off, yet the commercial would be right on. Very strange, and I attribute the problem to TNT not the TV as sometimes its good sometimes not. Everything else seems right on.

That's a shame, I guess some TV's are still having lip sync issues.....hope mine won't! I can tell you on my Sony XBR 960 TNT will sometimes have lip sync issues too, but never on any other channel or source. Maybe TNT is just weird?

Light a candle & count yourself lucky. Mine is very obvious on all of my HD channels. What bugs me more is that the DVD is also out of whack. My biggest problem is that if I return it, what the hell do I get as a replacement? Not the ultra reflective Toshiba, and I don't think anything (Samsung 8500) is worth 2x the price.

Yes your DVD Player & connection are why your seeing the results your seeing.

Look at the sammy 6000 0r vizio 551xvt.

Am I correct to assume that the Lip Sync issues are only if you are listening to the sound via the TV's speakers or does it also happen when using an AVR?

I don't have an XXLH90 yet but was considering the 47" or 55" model.
I have both a 37" and also the 42LB5D from LG.

I do not use it for watching TV, I would have it hooked up to a HTPC via HDMI and sound comes out over my Pioneer 7.1 AVR.
I'm assuming then that I would not experience the lip sync. issues?

While on the topic of lip sync. issues.
In our living room we have an 8 year old 46" Sony DLP TV.
It NEVER had any issues with lip sync. however... as of early this week it started and is quite noticeable on many stations.
Nothing was changed with the setup or hardware, just happened out of nowhere.
We live in South Florida and are using Comcast via their HD Cable Box connected via Component.

It depends on how you have it hooked up to the AVR. If you have HDMI into the TV and audio optical out to the AVR you still experience the problem. If you have optical audio out from the cable box to the AVR you do not have a problem. Also, switching the HDMI setting on the cable box from auto to L-PCM fixes the issue so you can use the first set up I mentioned.

I called on Wednesday night, and got a call back just now from a tech to discuss the issue.

As I've said in another post, I think that my problems were with TruMotion 240 enabled, and watching some glitchy channels/content (like TNT as other posters suggest). So, I told him I was happy sitting on my 3.13 firmware with TruMotion off for a bit to make sure it was / wasn't resolved.

He indicated that Comcast and/or HDMI passthru devices (receivers) are common sources of the problem, aside from old firmware.

I like the form factor of the Sammy UN series, but not all of the problems associated with them.

I switched back to the HDMI connection for the DISH 612 after trying both the HDMI and component connections and comparing these to 1080i cable TV (the cable system here has analog SD, digital SD, and 18 free digital HD channels without needing a converter box) this morning using the local CBS, FOX, and NBC morning talk shows. We are using the 47LH90's internal speakers on both sets.

1. There are audio and video level difference between the HDMI and component connections. The audio level is higher using the component connection. I had to set the BL to Low (as everyone else has recommended) and the Gamma to Medium or High to get acceptable black levels using the HDMI.

2. There are some audio Lip Sync issues using HDMI but I see this on some channels using the component connections as well. I even saw this with my old DISH 625 SD dual channel DVR and a Sony Vega CRT TV.

3. There has always been a few seconds difference in the audio/video signal between the cable signal and the same channel via satellite (DISH, DirecTV, and C-band). I discovered this in 1992 when I got my first C-band satellite system.

Now the big question is how many of you would have noticed the Lip Sync issue if you hadn't known about it before hand? It is most noticeable on talk/news shows during close-ups. My wife doesn't even notice it on her 47LH90, she sits about ~13 feet away. I sit ~12 feet away from mine. I'll bet it is less noticeable on the 47" compared to the 55".

It's a kludge tho. If you want to be able to use the TV as a "central" distro point for audio from all your HDMI devices (STB, DVD, etc), by changing to L-PCM, you loose your 5.1 audio.

That's the point. Since your TV Speakers cannot do 5.1 audio, your best option is to have the devices output in 2 channel audio.

This allows you to get the BEST Audio option from your TV.

I see the Lip Sync using the HDMI connection from the DISH 612 with TruMotion off and on.

Rick

My point tho was that it's much easier to use the TV as an audio "aggregator".

All your devices go to you TV via HDMI. All support 5.1 audio.

Then you need only one optical audio cable to go into your AVR; which coincidentally, (in many cases) only has one digital audio input anyhow.

If you change to PCM, then you have to run 3 extra cables from each device to your AVR, in order to still get 5.1 audio. As an added plus, if your AVR does not have multiple digital audio inputs (many don't), then you have to buy some type of "switcher" to handle the multiple audio paths, or else you must switch cables around manually every time you want to watch a particular device and enjoy 5.1.

I have not read any problem on the sammy 6000. Can you explain more? Please PM me if this is too off topic

Gotcha... In that case you are 100% correct

Ha, that TOSLINK switching sucks, I have a switcher for it now but it's not too big of a deal. You guys are making me worry with the lip syncing again, it sounded like the fix was a done deal!

I have the direct tv dvr and hd to a sammy 32 and sony 46 all HDMI with lipsync problems, tech told me to do a hard shutdown with the power on the dt receivers. when they rebooted my lip-sync problem was gone. Never had a problem with my mitsy.

bfj, for you, is better this lg or toshiba sv670???
