Hi, I just got an LG 55LH90 from BestBuy a few days ago and I've noticed, what I think, are a couple of unusual hardware issues.


1) Looking at the back top of the tv, just about an inch to the outside of the 3 center screws it looks like there are slight indents on the frame....this are also seen in the front top of the tv frame. You really have to look for them to spot them. They are so properly placed, I'm wondering if this is normal or if this is damaged?


2) Does the screen sit completely flush inside the frame,tightly all around? Say, how a laptop screen sits inside the bezel frame? My screen (the actual lcd part) looks to have a little give or wiggle slightly on the top part of the tv. Is this normal or again, some type of defect? For example, if I hold the frame and wiggle the tv slightly, the actual screen will shift a little. I checked the 5 screws behind the top part of the frame and they are very tight.


I hope I'm explaing these issues correctly and really hoping this is normal and I'm just paranoid...


Thanks

Go to a store and check out the display model and see if you see the same things. If so, it's probably just how the tv is made. If not, return it for another one.

you could call LG and ask them. after all, they make the tv's, i'm sure they would know if that is normal.

Does the tv work ok and are either of these anomalies noticeable when watching tv? If the tv performs great are you willing to take a chance taking it back for another (oops, they're out of them) that does have performance problems?

Couldn't say if there are performance problems as of yet...only been 3 days. I just know that it bothers me knowing that the LCD is not sitting correctly inside of the frame. When I open the stand doors or turn the TV on the swivel it makes the screen rattle...really don't think this is normal.


The indents on the frame leads me to believe this had a problem during shipping and that maybe there could be other issues that just haven't materialized yet.


Spoke to a Geeksquad guy at different BB and has the TV in stock and they are sending me it next week and taking this one swapped. He also said their floor model does not have blemishes on the frame and there's no play in the screen.


It's possible there will be issues with the swapped TV too, and if that's the case, I'll return and try a different model alltogether. Perhaps there is a bad epidemic of damaged LG TVs in NJ....it's possible. Nothing is perfect, but for $2K, I'd like something that is above average.

Sorry, I misunderstood. If the panel actually rattles in the frame definitely not normal and should be returned. Hope the replacement's ok, these are reputedly fantastic tvs.

There is wiggle room with all of them. It has been reported in the owner's thread though we don't know exactly why.

i was in a BB in northern NJ and the floor model did not wiggle as much as mine.....you had to force it to get any sort of movement.... it didn't shake back and forth to the point that you can see rather large gap....


we'll see when my replacement comes this week...maybe there are diff levels of space and this is indeed intentional....


but again, those indents on top of the tv might have something to do with it.

Are you comparing both TV's on or off or after running for a while? Some of the thought behind it is that the wiggle has to do with expansion with heat after being on a while. A TV at Best Buy would most likely have been running for longer than your own set when you test it. Keep us posted.

got my replacement tv and there is still wiggle but much much less.... the spacing from the top had much too wide a gap compared to this one....yes, with tv running for about an hour...


did some googling and the floating type screen is because of some magnets that are placed inside the frame which is related to the whole invisible speaker set up...


they think some of the magnets were missaligned or perhaps damaged, missing, etc...


i'm not really sure what the true issue is, but am happy i got the swap done.

I just got my LG 55LH90 a few days ago and noticed the exact same issue and have the same problem that they are now out of stock in the store. I have LG home service coming by this week. The lower portion of my screen feels somewhat fixed but the sides and the top wiggle which makes the screen rattle under vibration.


I asked about this issue in the User thread. Let you know what they find when service arrives.

Does anyone know if this is related to the "invisible speaker" design? The product information seems to indicate that the speakers are inside the frame and sound exits from edges of the LCD panel and the frame. Tried to get the information from LG support but they were zero help.

talks about how the invisible speaker works and there is some sort of magnet set up inside the frame all around...


basically what the guys (geeksquad) at BB said...those magnets may have been damaged or defective... perhaps yours is ok but they said mine had too wide a gap when compared to the floor model...


doesn't hurt to just have them come and look and see.

Service technician said that the LCD screen is defective. He said the LCD screen has a small metal frame that mounts it to the main frame. On my set, the LCD screen delaminated from the metal mounting frame. Not a good start for my first LG product.

same prognosis on mine then.... but guys who looked at mine did say that whatever was disconnected wasn't going to move any further and that the only thing i'd notice is the shake if i clean the screen or move the pedestal...should have no affect on picture quality....


then again, who knows a few years down the line....



glad you are getting it taken care of...my replacement was much more 'solid' feeling...

i never heard of a TV manufacturer intentionally putting a wiggle feature in a screen before. So to answer your question, no, the lcd screen is not suppose to wiggle.

there is supposed to be an intentional 'floating' like effect to the screen because of the invisible speaker system....but of course, not to the point where you start seeing an inch gap around the frame...

Normal for LCD panel glass itself to move within the LCD frame. Had to to allow for thermal expansion and least mechanical stress (this causes clouding and flashlighting) distortions.


Cheers, Wizard
