Official LG "XXLH90" 240hz LED Owners Forum [NO PRICE TALK] - Page 156

Some of you may remember me posting about a year ago that LG had failed to repair or remedy the digital pass-thru over optical issue in my 55LH90. Some may remember that LG offered to replace the set with a 2011 model as soon as they arrived on the market. I was told this would take 1-3 months.

Today, eleven and one half (11.5) months later, I called to ask what was taking so long. They told me some sob story about a customer service executive on leave for a death in the family, and my case being "accidentally" closed. They told me they would re-review my case and call back in a bit before the end of the day.

In 40 minutes, I received a call back from "Stan" stating that they would offer me the 55LW6500 as a replacement TV set. I countered with the statement that the LW6500 line does not offer local dimming, and has been reviewed as having washed out and uneven black levels across the screen - one of the main reasons behind my purcjase of the LH90. He said this was a take it or leave it. The only other option they proposed was to refund me my money and I return the set.

I researched this set for months before buying it. It has the best black levels of any LCD I've seen. It has the most even blacks on a completely black screen. I purchased components to talk on the "Simpilink" network to make use of a single remote. Returning it is not an option.

So there you have it folks! They strung me along for more than a year (I bought the set in March of 2010) and now they have offered me a set not even comparable to replace their design flaw. They orignially offered me $400 to compensate me for my trouble. By my figuring, they owe me $800 now, plus damages.

So my parting line to you all? Stay away from LG. They aren't making high quality sets anymore. Their customer service rates a 1 out of 10. They arent' afraid to make advertising claims that are completely untrue, and they offer no real recourse.

If I were you, I would have demanded the same model and not even consider a 2011 replacement. If at that time they said no LH90 was available because it was discontinued, I would have requested a refund and bought that model or the 47 LH90 from some online source.

No, the issue is with the whole LH90 series. They used a faulty algorithm to process audio that resulted in lip sync issues. they resolved the issue with lip sync by disabling the pass-thru option and forcing the TV to downmix to stereo PCM.

They told me they couldn't resolve it, and the 2010 models used the same algorithm. Hence, different model.

At that point, I would have requested a refund and bought some other brand.

I have searched and searched before i wanted to post this question. I have a 55LH90 attached to a MediaCenter computer, the computer will be running XBMC.

The problem is Windows recognizes the Monitor as a "Default" monitor and not an LG, are there any drivers out there to install so I can get a compatible selection of Resolutions and refreash rates for this monitor?

If your video drivers are current and you're plugging the display in via HDMI you shouldn't need any drivers. The PC should detect 1920x1080 and the refresh rate is irrelevant but should be 60Hz (okay, 59.9something). Make sure you set the TV's aspect ratio to "just scan."

If you have a display that you consider to have very good video quality why not spend $3 - $400 on an inexpensive receiver and a pair of speakers and be done with it? You'll get better sound anyway. Would you go to a theater that plopped a table radio in front of the screen for their sound?

Yes, LG has lousy tech support. So does everyone else other than Visio; they have none. If you've ever dealt with HP you'd know this isn't even in the same league. Seagate shipped server drives with a failure rate over 90% and they claim "it's just firmware."

Just because that's the way they used to come why do people still insist on having sound come out of their video output device? Do you stare at your speakers waiting for a picture?

The laws of physics dictate that an enclosure that small (and made of plastic) can't sound good anyway and no amount of electronic manipulation can change that (despite what Bose may tell you). Speakers are motors that move air. If there isn't enough surface area to move a sufficient amount of air then there is no way to produce good sound.

My PC recognizes my 55lh90 just fine. You should get a new video card!

I have the option of getting a used 55LH90 or a new 55LW6500 for roughly the same price ... What would users here recommend?

I would suggest the 55LW6500. I have the 55LH90 and LOVE it, but the 6500's 3D capability trumps it if compared at equal price points.

Bought a 55LH90 for 1349 Nov 11th 2010.....

Fast forward to today.......and during dark scenes I get a pulsing backlight effect.... a flicker..... from dark to BRIGHT to dark and back. If I pause a dark scene it doesn't have the problem.

Of course it has a 1 year warranty.

I'm going to go through this thread and search but does anyone have any advice about getting this fixed? Does it on multiple channels, hooked up to a windows media center pc via HDMI, directly plugged into the video card.

Local dimming on or off, doesn't change the problem.

Is tru motion set to off? If not, turn tru motion to off.

Well my backlight is completely gone in my 47LH90. Tried plugging in several different sources, hit the menu button, everything, the screen is totally black. Has anyone attempted a repair on this? Is there a servicable inverter or power supply for the LED backlighting? I'm pretty handy with a soldering iron.

Hi: I've had my 55LH90 for almost two years and I'm not sure if what's happening is getting slowly worse or even has been there all along because it's a bit subtle and I can't remember so well. I tried to take photos (attached) to show the issue with some success.
When I am watching with all the lights off, the screen is washed out somewhat (as in not black) in the framing areas above and below the image. When black areas of the image are up against the top or bottom it runs together basically showing that ALL the black areas are washed out. Is this normal?

Thanks

Sounds like the gamma may not be set correctly. Usually, it's set to medium. Try setting it to high and see if that reduces the washed out effect. Setting it to high may not be desirable in that different shades of near black won't be distinguishable. But, try it and see.

After several years of trying to calibrate first a couple of 55LH90s, then later a couple of 55LHXs, found LG gives you, out of whack White Balances that aren't even near their own specs! Have now purchased the Service Remote and calibrate the Service Menu White Balance Cool, Medium and Warm - then calibrate the IRE's. Once these are done, the CMS values fall right into place and they can be left at Zero.
The 55LHXs are now amazing to look at - will now take this new calibration system to my daughter's, and see how well it now brings out the PQ of the 55LH90 I sold her. Imagine there will be definite improvement.

How much do you charge?

It's family, you're expected to do it for Free!

Hope you post your results!

Daughter's Birthday in March - will be going there at that time for the calibration.
May also get a chance to calibrate my other sold 55LH90 sometime in the future.

Woke up this morning and turned on my 3 year old 47lh90 and the blue power light came on but the screen stayed off and no sound. Does that sound like bad caps?

Remove the Power Plug from the set overnight - re-try the next morning. You may want to also unplug any Video Plugins before re-starting.
If the set comes on, then turn off TV and re-install one plugin and retry. Do this for each input.
If this doesn't work - LG Repair Depot next.

You dont need a service remote if you have a harmony remote or a one for all.
I can access anything the service remote has.

Just for reference if anyone else experiences this problem....I opened up the tv and all the caps on the power supply board looked perfect however I did find the soldered on ceramic fuse for the high voltage side on the board was blown. I ordered a replacement fuse and soldered it in but the new one blew as soon as I flipped the switch so that told me that some other component on the power supply had apparently gone bad causing a dead short. I found a onlone store that sold the power supply board for this tv (for less than a tv repairman would have charged to even look at my tv) and ordered it. Got it about 6 days later, installed it and the tv has been working fine since. Glad it was something I could figure out this time...we don't have the money to replace this tv right now.

I have the 42ld550, and I use it mostly for playing movies from my computer, using TwonkyMedia. I'm seeing lots of lip syncing issues. I've been reading about others having this issue but not related to this. Any suggestions?

Sorry for the long wait to my reply, but:

compcond, I don't think you read my original posts. (I understand. There are a lot of pages here) At the time of this post, I had a reliable Denon receiver and (to my mind) incredible Pinnacle speakers that were built before the latest-greatest HDMI was being drafted. The reciever only had TOSLink or COAX digital inputs. LG provided a mechanism to forward audio that it recieved on its HDMI ports out along an optical cable. This mechanism was intentionally reduced in functionality by software designers at LG to mitigate a lip-sync issue (that was itself caused by using sub-standard algorithms to decode audio and video within a reasonable time in reference to eachother) with the result that instead of Dolby Digital 5.1 or DTS being passed untouched or even re-encoded, it was down-mixed to 2-channel PCM. LG Pledged to repair this problem.
They told me they would:
A) Let me return the TV for full MSRP refund ($2899 IIRC)
B) Let me keep the TV and they would send me $400 in compensation, with no repair.
C) Offer me a replacement from their flagship line of TVs from the 2011 model line-up when it came out, which was supposed to be 12-2011

You see, they knew the problem was a hardware-centered one, and the same hardware was present in the 2010 TV sets. I would thusly need to wait until 2011 sets were released to receive effective replacement.

Months (5+) later, they hadn't called me back, so I called and was told that Choice "A" was still an option, but at the lowest discount price available on the market at that time, instead of MSRP. Choice "C" was reduced to the 55LW6500, which can hardly be considered a flagship television like the LH90 or the LX90 was. Mentioning choice "B" earned me a, "You're kidding, right?!?"

That is why I posted what I posted.

I would never complain about audio quality coming from built-in speakers on a TV. If I thought somebody else did, I would probably have responded as you did.

Know this: As of right now, if I call LG for a different problem with my TV, my serial number has been entered into their system and I get forwarded right back to the same guy that was obviously advanced in his organization for his ability to say "No" to customers, event those that have made deals in writing with his company. He tells me he cannot help me any longer, as my "offer expired" 24-hours after we hung up that day.

My post was designed to let others know what a promise from LG means, not to complain about awful sound froma 15w speaker in a plastic partial enclosure.

I guess I'm lucky - both my former 55LH90s still going for their new owners.

Please note the following: after having my older 32" LG quit at the mother-in-laws. Wife bought her a new one. Disassembled the old one to find: #1 - Most TV Manufacturer's are only using 10V Capacitors, instead of 16V. Found 4 popped caps - $60 to have board repaired and now back up and running in our guest bedroom.
You could also purchase the Pixel Protector Blu-ray, and try the overnight Pixel Washes. This really cleans up our panels. Note: Pixel Wash one, 6 hours, second wash 2 hours, and the last, for 1 hour.

Guys i am having a strange issue with my 55LH90 . The remote control signal doesnt work properly. The TV doesnt change channels and adjusts volume sometimes. Now its getting worse day by day. I tried with LG remote and other universal remotes. Its not the remote control that is the problem. Its the TV. How do i go about fixing this issue ?

Looks like the remote sensor is gone. Older LG TV's had the same problem. But cleaning up the Remote-in Jack solved the problem. But the LH90 series doesnt have a remote-in jack. Just the sensor in the front. I tried to open up the sensor. But its kind of tight. I didnt wanted to break it. Hence left it there. Any ideas ?

Any progress?
